By Richard Stone, May. 5, 2021 , Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world’s worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. “It’s like the embers in a barbecue pit,” says Neil Hyatt, a nuclear materials chemist at the University of Sheffield. Now, Ukrainian scientists are scrambling to determine whether the reactions will wink out on their own—or require extraordinary interventions to avert another accident.
Sensors are tracking a rising number of neutrons, a signal of fission, streaming from one inaccessible room, Anatolii Doroshenko of the Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv, Ukraine, reported last week during discussions about dismantling the reactor. “There are many uncertainties,” says ISPNPP’s Maxim Saveliev. “But we can’t rule out the possibility of [an] accident.”
The neutron counts are rising slowly, Saveliev says, suggesting managers still have a few years to figure out how to stifle the threat. Any remedy he and his colleagues come up with will be of keen interest to Japan, which is coping with the aftermath of its own nuclear disaster 10 years ago at Fukushima, Hyatt notes. “It’s a similar magnitude of hazard.”
The specter of self-sustaining fission, or criticality, in the nuclear ruins has long haunted Chernobyl. When part of the Unit Four reactor’s core melted down on 26 April 1986, uranium fuel rods, their zirconium cladding, graphite control rods, and sand dumped on the core to try to extinguish the fire melted together into a lava. It flowed into the reactor hall’s basement rooms and hardened into formations called fuel-containing materials (FCMs), which are laden with about 170 tons of irradiated uranium—95% of the original fuel.
The concrete-and-steel sarcophagus called the Shelter, erected 1 year after the accident to house Unit Four’s remains, allowed rainwater to seep in. Because water slows, or moderates, neutrons and thus enhances their odds of striking and splitting uranium nuclei, heavy rains would sometimes send neutron counts soaring. After a downpour in June 1990, a “stalker”—a scientist at Chernobyl who risks radiation exposure to venture into the damaged reactor hall—dashed in and sprayed gadolinium nitrate solution, which absorbs neutrons, on an FCM that he and his colleagues feared might go critical. Several years later, the plant installed gadolinium nitrate sprinklers in the Shelter’s roof. But the spray can’t effectively penetrate some basement rooms.
Chernobyl officials presumed any criticality risk would fade when the massive New Safe Confinement (NSC) was slid over the Shelter in November 2016. The €1.5 billion structure was meant to seal off the Shelter so it could be stabilized and eventually dismantled. The NSC also keeps out the rain, and ever since its emplacement, neutron counts in most areas in the Shelter have been stable or are declining.
But they began to edge up in a few spots, nearly doubling over 4 years in room 305/2, which contains tons of FCMs buried under debris. ISPNPP modeling suggests the drying of the fuel is somehow making neutrons ricocheting through it more, rather than less, effective at splitting uranium nuclei. “It’s believable and plausible data,” Hyatt says. “It’s just not clear what the mechanism might be.”
The threat can’t be ignored. As water continues to recede, the fear is that “the fission reaction accelerates exponentially,” Hyatt says, leading to “an uncontrolled release of nuclear energy.” There’s no chance of a repeat of 1986, when the explosion and fire sent a radioactive cloud over Europe. A runaway fission reaction in an FCM could sputter out after heat from fission boils off the remaining water. Still, Saveliev notes, although any explosive reaction would be contained, it could threaten to bring down unstable parts of the rickety Shelter, filling the NSC with radioactive dust.
Addressing the newly unmasked threat is a daunting challenge. Radiation levels in 305/2 preclude getting close enough to install sensors. And spraying gadolinium nitrate on the nuclear debris there is not an option, as it’s entombed under concrete. One idea is to develop a robot that can withstand the intense radiation for long enough to drill holes in the FCMs and insert boron cylinders, which would function like control rods and sop up neutrons. In the meantime, ISPNPP intends to step up monitoring of two other areas where FCMs have the potential to go critical.
The resurgent fission reactions are not the only challenge facing Chernobyl’s keepers. Besieged by intense radiation and high humidity, the FCMs are disintegrating—spawning even more radioactive dust that complicates plans to dismantle the Shelter. Early on, an FCM formation called the Elephant’s Foot was so hard scientists had to use a Kalashnikov rifle to shear off a chunk for analysis. “Now it more or less has the consistency of sand,” Saveliev says.
Ukraine has long intended to remove the FCMs and store them in a geological repository. By September, with help from European Bank for Reconstruction and Development, it aims to have a comprehensive plan for doing so. But with life still flickering within the Shelter, it may be harder than ever to bury the reactor’s restless remains.
Fact check: 5 myths about the Chernobyl nuclear disaster
Monday marks the 35th anniversary of the Chernobyl nuclear disaster. What happened in the former Soviet Union on April 26, 1986, is no longer a secret. DW,
Is Chernobyl the biggest-ever nuclear disaster?
The 1986 nuclear disaster at the Chernobyl nuclear power plant near the city of Pripyat in northern Ukraine is often described as the worst nuclear accident in history. However, rarely is this sensational depiction clarified in more detail.
The International Nuclear and Radiological Event Scale (INES) does classify nuclear events on a scale of zero to seven, breaking them down into accidents, incidents and anomalies. It was introduced in 1990 after being developed by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organization for Economic Cooperation and Development (NEA/OECD). Level seven denotes a “major accident,” which means “major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures.”
Both the Chernobyl and 2011 Fukushima disaster have been categorized as such. But INES does not allow for nuclear events to be classified within a level.
If the term nuclear disaster is not only used to describe events, or accidents, in nuclear reactors but also radioactive emissions caused by humans then there are many occasions when human-caused nuclear contamination has been greater than that of the Chernobyl disaster, explained Kate Brown, professor of science, technology and society at the Massachusetts Institute of Technology.
“Let’s take the production of plutonium,” she told DW, referring to the American and Soviet plants that produced plutonium at the center of a nuclear bomb. “Those plants each issued as part of the normal working everyday order at least 350 million curies [a unit of radioactivity — Editor’s note] into the surrounding environment. And that was not an accident.
“Let’s look at, even more dire, the issuance of radioactive fallout in the detonation of nuclear bombs during the periods of nuclear testing ground, which were located throughout the world, ” she continued. “Those just take one isotope, one radioactive iodine, which is harmful to human health because it’s taken up by the human thyroid, causing thyroid cancer or thyroid disease.
“Chernobyl issued 45 million curies of radioactive iodine just in two years of testing, in 1961 and 1962. The Soviets and the Americans issued not 45 million curies, but 20 billion curies of radioactive iodine,” she said. And these tests, she added, were by design — not due to an accident or human error.
Are there mutants in the exclusion zone?
………….. “The influence of ionizing radiation may cause some restructuring in the body, but mostly it simply reduces an organism’s viability,” he explained, giving the example of high embryo fatalities in rodents due to genomic defects that prevented the organism from functioning. Those animals that survive the womb sometimes have disabilities that prevent them from staying alive in the wild. Vishnevsky and his colleagues have conducted research into thousands of animals in the exclusion zone, but have not found any unusual morphological alterations.
“Why? Because we were always dealing with animals that had survived and had won the fight for survival,” he said. He added that it was difficult to compare these animals with creatures that scientists had deliberately exposed to radiation in laboratories.
“That’s a very seductive idea, that human messed up nature and all they have to do is step away and nature rewrites itself,” she said. In reality, however, biologists say that there are fewer species of insects, birds and mammals than before the disaster. The fact that some endangered species can be found in the exclusion zone is not evidence of the area’s health and vitality.
Has nature reclaimed the site of the disaster?
Reports entitled “Life Flourishing Around Chernobyl” and photo series suggesting that the exclusion zone has become a “natural paradise” might give the impression that nature has recovered from the nuclear disaster. But Brown, who has been researching Chernobyl for 25 years, is adamant that this is “not true.”
“That’s a very seductive idea, that human messed up nature and all they have to do is step away and nature rewrites itself,” she said. In reality, however, biologists say that there are fewer species of insects, birds and mammals than before the disaster. The fact that some endangered species can be found in the exclusion zone is not evidence of the area’s health and vitality.
On the contrary: there has been a significant increase in the mortality rate and a lowered life expectancy in the animal population, with more tumors and immune defects, disorders of the blood and circulatory system and early ageing.
Scientists have attributed the apparent natural diversity to species migration and the vastness of the area. “The exclusion zone comprises 2,600 square kilometers [about 1,000 square miles]. And to the north are another 2,000 square kilometers to the north is Belarus’ exclusion zone,” said Vishnevsky. “There are also areas to the east and west where the human population density is extremely low. We have a huge potential for preserving local wild fauna.” That includes lynxes, bears and wolves which need a great deal of space.
But even 35 years after the disaster the land is still contaminated by radiation, a third of it by transuranium elements with a half-life of more than 24,000 years.
Is it safe for tourists to visit Chernobyl?
The exclusion zone was already a magnet for disaster tourists, but in 2019 annual numbers doubled to 124,000 after the success of the HBO miniseries Chernobyl. The State Agency of Ukraine on Exclusion Zone Management has set up a number of routes so tourists can visit the region by land, water or air. It has also drawn up a number of regulations to protect visitors, stipulating that people must be covered from head to toe. They shouldn’t eat any food or drink outside, and they should always follow official paths. It’s estimated that the radiation dose received over a one-day visit does not exceed 0.1 millisievert (mSv) — roughly the same dose that a passenger would be exposed to on a long-distance flight from Germany to Japan, according to Germany’s Federal Office for Radiation
Are there people living in the area?
Today, Pripyat, the closed city built to serve the nuclear plant and house its employees, is often described as a ghost town, as is the nearby city of Chernobyl.
However, neither has been entirely empty since 1986. Thousands of people, usually men, have stayed there, often working two-week shifts and ensuring that the crucial infrastructure in both cities continues to function. After the explosion in reactor No. 4, reactors 1, 2 and 3 continued to operate, closing down only in 1991, 1996 and 2000. Special units of the Ukrainian Interior Ministry police the zone. There are also stores and at least two hotels in Chernobyl, which are mainly for business visitors.
There are also a number of unofficial inhabitants, including people who used to live in the area and have chosen to return. They have settled in villages that were evacuated after the disaster. The exact number of people is unknown: when DW asked the State Agency of Ukraine on Exclusion Zone Management how many people lived in Chernobyl, the official answer was “nobody.”
In 2016, about 180 people were thought to be living in the entire exclusion zone. Because they tended to be older, this number may well have fallen. Even though these locals are officially only tolerated, the state does support them in their everyday lives. Their pensions are delivered once a month, and every two to three months they are supplied with food by a mobile store. https://www.dw.com/en/fact-check-5-myths-about-the-chernobyl-nuclear-disaster/a-57314231
Below – a video from past years tells the earlier story of the chernobyl disaster
DOES CHERNOBYL STILL MATTER?https://www.publicbooks.org/does-chernobyl-still-matter/ 11.22.2019 BYGABRIELLE HECHTSince it first announced electricity “too cheap to meter,” in the 1950s, the nuclear industry has promised bountiful futures powered by a peaceful—and safe—atom. Design principles, the industry claims, limit the chances of core damage to one incident every 50,000 reactor-years of operation. History, however, has delivered a different verdict: together, Three Mile Island, Chernobyl, and the three Fukushima reactors represent five meltdowns in only 100 reactor-years. What lessons do these accidents hold for the future of nuclear power?
Each meltdown has impelled design, operational, and regulatory changes, increasing the cost of nuclear power. Today, says the industry, the technology is safer and more vital than ever. No other source of electricity can offer so much baseload power with so few carbon emissions. But who can make money when a single US Nuclear Regulatory Commission (NRC) inspection costs $360,000?
For the current US administration, the remedy for waning profits lies in cutting inspection hours. In a July 2019 proposal, which drew heavily on nuclear industry recommendations, the NRC also suggested crediting utility self-assessments as “inspections” and discontinuing press releases about problems of “low to moderate safety or security significance.” Translation: fewer inspections, less transparency, and weaker environmental and health oversight at the nation’s nuclear power plants.
The cause, costs, and consequences of the 1986 Chernobyl accident loom large in these battles. Was Chernobyl a fluke, the result of faulty technology and a corrupt political system? Or did it signal a fundamentally flawed technological system, one that would never live up to expectations?
Even simple questions are subject to debate. How long did the disaster last? Who were the victims, and how many were there? What did they experience? Which branches of science help us understand the damage? Whom should we trust? Such questions are tackled, with markedly different results, in Serhii Plokhy’s Chernobyl, Adam Higginbotham’s Midnight in Chernobyl, Kate Brown’s Manual for Survival, and HBO’s Chernobyl (created by Craig Mazin).
Serhii Plokhy’s book and Craig Mazin’s miniseries, both entitled Chernobyl, focus primarily on the accident and its immediate aftermath. Both build on the standard plotline embraced by nuclear advocates.
In this narrative, Soviet love of monumental grandeur—or “gigantomania”—led to the selection and construction of Chernobyl’s RBMK1 design: an enormous 1000-megawatt reactor, powered by low-enriched uranium fuel, moderated by graphite, and cooled by water. The utterly unique RBMK had fundamental design flaws, hidden by corrupt state apparatchiks obsessed with secrecy, prestige, and productivism. Operators made inexcusable errors. The accident was inevitable. But the inevitability, Plokhy and Mazin affirm, was purely Soviet.
Plokhy gives more backstory. The enormous scale of Soviet industrialization put huge strains on supply chains, resulting in shoddy construction. Some of the men in charge had no nuclear background. The pressure to meet production quotas—and the dire consequences of failure—led bureaucrats and engineers to cut corners.
For both Plokhy and Mazin, these conditions at Chernobyl came to a head during a long-delayed safety test. When the moment to launch the test finally arrived, shortly before midnight on April 25, 1986, there was confusion about how to proceed. The plant’s deputy chief engineer, Anatolii Diatlov, who did have extensive nuclear experience, believed he knew better than the woefully incomplete manuals. He pushed operators to violate the poorly written test protocol. (Disappointingly, Mazin’s miniseries portrays Diatlov more as a deranged bully than as someone with meaningful operational knowledge.)
The reactor did not cooperate: its power plummeted, then shot back up. Operators tried to reinsert the control rods. The manual didn’t mention that the RBMK could behave counterintuitively: in other reactor models, inserting control rods would slow down the fission reaction, but in the RBMK—especially under that night’s operating conditions—inserting the rods actually increased the reactivity. Steam pressure and temperature skyrocketed. The reactor exploded, shearing off its 2000-ton lid. Uranium, graphite, and a suite of radionuclides flew out of the core and splattered around the site. The remaining graphite in the core caught fire.
At first, plant managers didn’t believe that the core had actually exploded. In the USSR—as elsewhere—the impossibility of a reactor explosion underwrote visions of atomic bounty. Nor did managers believe the initial radiation readings, which exceeded their dosimeters’ detection limits. Their disbelief exacerbated and prolonged the harm, exposing many more people to much more radiation than they might have otherwise received. Firefighters lacked protection against radiation; the evacuation of the neighboring town of Pripyat was dangerously delayed; May Day parades proceeded as planned. Anxious to blame human operators—instead of faulty technology or (Lenin forbid!) a broken political system—the state put the plant’s three top managers on trial, in June 1987, their guilt predetermined.
Mazin’s miniseries follows a few central characters. Most really existed, though the script takes considerable liberties. The actions of the one made-up character, a Belarusian nuclear physicist, completely defy credibility. But hey, it’s TV. Dramatic convention dictates that viewers must care about the characters to care about the story. Familiar Cold War tropes are on full display: defective design, craven bureaucrats, and a corrupt, secrecy-obsessed political system. A few anonymous heroes also appear: firefighters, divers, miners, and others who risked their lives to limit the damage.
Nuclear advocates—many of whom believe that Chernobyl was a fluke, one whose lessons actually improved the industry’s long-term viability—object to the unrealistically gory hospital scenes portraying acute radiation sickness. But these advocates should feel appeased by the closing frames, which ignore the long-term damage caused by the accident.
Instead, the miniseries skates over post-1987 events in a few quick captions. The managers went to prison, a scientist committed suicide, people were evacuated. Yes, controversy persists over the number of casualties (31? That was the official Soviet number. How about 4,000? That’s the number issued by the Chernobyl Forum, an entity that includes representatives from the World Health Organization, the International Atomic Energy Agency, and other international organizations. As for the 41,000 cancers suggested by a study published in the International Journal of Cancer—that number isn’t even mentioned). But all is under control now, thanks to the new confinement structure that will keep the area “safe” for a hundred years. Mazin himself insists that the show isn’t antinuclear.

But all is under control now, thanks to the new confinement structure that will keep the area “safe” for a hundred years. Mazin himself insists that the show isn’t antinuclear.
Plokhy also addresses the accident’s role in the breakup of the USSR. In 2006, Mikhail Gorbachev famously speculated that “the nuclear meltdown at Chernobyl, even more than my launch of perestroika, was perhaps the real cause of the collapse of the Soviet Union.” Plokhy delivers details. Ukrainian dissidents trained their writerly gaze on Chernobyl, vividly describing the damage. Street demonstrations depicted the accident and its coverup as “embodiments of Moscow’s eco-imperialism.” This vision spread and morphed, animating protests in Belarus—also severely contaminated by the accident—and elsewhere. Chernobyl served as Exhibit A for why the republics should shed the Soviet yoke.
If you’re hoping for clear technical explanations, however, you’ll be disappointed. A stunning error mars the first few pages: Plokhy declares that each RBMK produced 1 million megawatts of electricity. This is off by a factor of 1,000. Typo? No, because he doubles down in the next sentence, affirming that the station produced 29 billion megawatts of electricity in 1985. He gets the orders of magnitude right later on, but these early missteps undermine reader confidence. Muddled technical descriptions and uninformative diagrams add to the confusion.
Readers seeking to understand the technology should turn instead to journalist Adam Higginbotham’s Midnight in Chernobyl. He uses global nuclear history to illuminate Soviet efforts to manage the Chernobyl crisis. By comparing the crisis to reactor accidents elsewhere, Higginbotham shows that deep vulnerabilities are widespread. Plokhy’s engineers and managers seem bumbling, verging on incompetent. Higginbotham’s more nuanced portrayal reflects how complex engineering projects of all types necessitate informed improvisation. The three-dimensional world doesn’t faithfully obey manuals. Adjustments are always required.
Higginbotham and Plokhy differ most starkly in their treatment of Soviet reactor choice. In the1960s, technocrats weighed the RBMK design against the VVER,2 the Soviet version of a pressurized light water reactor similar to those sold by Westinghouse and used in the United States. For Plokhy, it’s simple. The VVER was “safe.” The RBMK was not, but its size and cost appealed to Soviet productivism.
Higginbotham, however, wisely relies on Sonja Schmid’s pathbreaking Producing Power: The Pre-Chernobyl History of the Soviet Nuclear Industry (2015) to show that reactor safety isn’t a yes-no proposition. Plutonium-producing reactors similar to the Soviet RBMK (albeit half its size) existed in North America and Western Europe. Like nine of its French cousins, the RBMK could be refueled while continuing to operate. This presented significant advantages: light water reactors had to shut down for refueling, which entailed several weeks of outage. Even the risks presented by RBMK design vulnerabilities seemed manageable. “Nuclear experts elsewhere considered the RBMK design neither technologically novel nor particularly worrisome,” Schmid writes, noting that “what we consider good and safe always depends on context.” In the Soviet context, “selecting the RBMK made very good sense.”
Neither Schmid nor Higginbotham absolves the Soviet technopolitical system. The specific circumstances that led to Chernobyl’s explosions might not recur. But, as sociologist Charles Perrow has been arguing since his 1983 book Normal Accidents, highly complex technological systems create unpredictable situations, which inevitably lead to system failures. The question is not whether an accident of Chernobyl’s gravity can happen elsewhere, but how to prepare for the consequences when it does.
That’s one of the questions Kate Brown considers in Manual for Survival. Offering a wealth of new information and analysis, Brown speeds past the reactor explosion. Instead, she focuses on dozens of previously untold stories about how people coped with their newly radioactive lives.
Brown’s protagonists include women who worked at a wool factory fed by contaminated sheep and butchers ordered to grade meat according to radioactivity. Ukraine, we learn, kept serving as the Soviet breadbasket, despite food radiation levels that exceeded norms. The concentrations of radionuclides were biomagnified by receptive organisms and ecologies, such as mushrooms, wild boar, and the Pripyat Marshes. Defying expectations, some foods, over time, have even become more contaminated.
Brown’s descriptions add historical flesh to arguments first developed by Olga Kuchinskaya, in her 2014 book on Belarus’s Chernobyl experience, The Politics of Invisibility: Public Knowledge about Radiation Health Effects after Chernobyl.
Since the first studies of bomb survivors in Hiroshima and Nagasaki, science on the biological effects of radiation exposure has been subject to controversy. Like all scientific work, these early survivor studies had limitations. Exposure estimates were unreliable.
The largest study began data collection five years after the Hiroshima and Nagasaki blasts, so it didn’t include people who died or moved between 1945 and 1950. Another problem lies in the applicability of these studies. Bomb exposures, such as those in Japan, mostly consist of high, external doses from one big blast. Yet postwar exposures have mainly consisted of low doses, delivered steadily over a long period. They often involve internal exposures—such as inhalation of radioactive particles or consumption of irradiated food—which can be deadlier.
Irrespective of their limitations, however, the findings of these survivor studies have served as the basis for establishing regulatory limits for all types of radiation exposures. Critics argue that extrapolating from the Japan data underestimates low-dose effects: If you’ve already decided that the only possible health effects are the ones you’ve already found, surely you’re missing something? Among other limitations, studies of external gamma radiation exposures cannot illuminate the long-term health effects of inhaling radioactive alpha particles.
Brown injects the work of Dr. Angelina Gus’kova into this story. Gus’kova started treating radiation-induced illnesses in the 1950s, while working at the top-secret Mayak plutonium plant (where the radioactive spills from a 1957 accident continue to contaminate people, land, and water). A neurologist, Gus’kova made observations that extended beyond the narrow cancer focus of most Western practitioners who studied the health effects of radiation exposure. Her patients displayed a wide range of symptoms, which Gus’kova and her colleagues dubbed “chronic radiation syndrome.” Not that they neglected cancer: a 40-year study of 1.5 million people who lived near Mayak found significantly higher cancer and death rates than those reported in Hiroshima and Nagasaki.
The Soviet rubric of “chronic radiation syndrome” did not exist in the West. Yet Gus’kova’s findings did align with those of dissident scientists in the US and the UK. Thomas Mancuso, for example, was pushed out of the US Atomic Energy Commission because he refused to give the Hanford plutonium plant a clean bill of health after finding that workers there sustained high rates of cardiovascular disease, immune system damage, and other illnesses.
Alice Stewart, meanwhile, was shunned by the British establishment after her 1956 research showed that x-raying pregnant women increased the risk of cancer and leukemia in their children by 50 percent. Over the years, these and other scientists whose data challenged the findings of American and European nuclear establishments found themselves sidelined and defunded.
In tandem with perestroika, Chernobyl opened communication between Soviet and Western nuclear experts, engendering what Brown calls an “unholy alliance.” In 1990, the International Atomic Energy Agency (IAEA) sent a mission to Belarus and Ukraine to assess radiation damage. Belarusian scientists reported rising rates of many diseases in contaminated areas. Nevertheless, the IAEA team rejected radiation as a possible cause. Such correlations didn’t appear in Western data.
Instead, the IAEA teams used dose estimates provided by distant Moscow colleagues and ignored local Belarusian and Ukrainian descriptions of people’s actual consumption habits, which included significant amounts of contaminated food and milk. The IAEA assessments neglected the internal exposures resulting from this consumption. Yet these assessments now serve as international reference points. “Underestimating Chernobyl damage,” Brown warns, “has left humans unprepared for the next disaster.”
For some, hope springs eternal. In 2017, Chernobyl’s “New Safe Confinement” finally became operational, after two decades of design and construction. This $1.7 billion structure aims to contain the spread of radioactive rubble while workers inside dismantle the reactor and its crumbling sarcophagus. Ownership was transferred from the builders of the structure to the Ukrainian government in July 2019.
At the transfer ceremony, newly elected Ukrainian President Volodymyr Zelensky announced a tourism development plan for the radioactive exclusion zone, including a “green corridor” through which tourists could travel to gawk at the remains of Soviet hubris. “Until now, Chernobyl was a negative part of Ukraine’s brand,” declared Zelensky, who was nine years old when the reactor exploded. “It’s time to change.” (Zelensky further demonstrated his dedication to “branding” two weeks after this ceremony, when he emphasized his recent stay in a Trump hotel during his now-infamous phone conversation with the US president.)
Change also seems possible to Plokhy, who optimistically predicts that new reactor designs will be “cheaper, safer, and ecologically cleaner.” But Allison Macfarlane, who chaired the US Nuclear Regulatory Commission under Obama, recently noted that these “new” options are actually “repackaged designs from 70 years ago.” They still produce significant quantities of highly radioactive, long-lived waste.
Meanwhile, regulators in France—the world’s most nuclear nation—are taking the opposite approach from the United States’ NRC. Rather than rolling back oversight, France is intensifying inspections of their aging reactor fleet. After four decades of operation, many French reactors have begun to leak and crack. Keeping them operational will cost at least $61 billion. Despite the phenomenal cost, there are many who believe such an investment in the nuclear future is worthwhile.
Brown is far less sanguine about our nuclear future. Predictably, she has been denounced for believing marginal scientists and relying too heavily on anecdotal evidence. She does occasionally go overboard in suggesting conspiracy. Cover-ups clearly occurred on many occasions, but sometimes people were just sticking to their beliefs, trapped by their institutional and disciplinary lenses. Brown’s absence of nuance on this point matters, because the banality of ignorance—its complicity in all forms of knowledge production—can be more dangerous than deliberate lies: more systemic, harder to detect and combat.
Overall, though, Brown is on the right track. Many modes of scientific inquiry aren’t equipped to address our most urgent questions. Clear causal chains are a laboratory ideal. The real world brims with confounding variables. Some scientists studying Chernobyl’s “exclusion zone”—the region officially declared uninhabitable due to contamination—are trying new techniques to grapple with this reality. Tim Mousseau and Anders Møller, for example, collect data on the zone in its ecological entirety, rather than focusing on single organisms. Their findings belie romantic tales of wildlife resurgence (such as the one offered up by a 2011 PBS special on the radioactive wolves of Chernobyl). They too have met resistance.
How, then, can we harness the immense power of scientific analysis while also acknowledging its limitations? The nuclear establishment is quick to lump its opponents together with climate change deniers and anti-vaxxers. Some may deserve that. But much dissident science is well executed. So how do we, the lay public, tell the difference? How can dissent and uncertainty serve, not as a block to action, but as a call?
One way: we can refuse to see Chernobyl and its kin as discrete events of limited duration. Brown, for example, treats Chernobyl as an acceleration of planetary-scale contamination that began with the atomic arms race.
Let’s be clear: the contamination continues. After the triple meltdown at Fukushima, scientists found highly radioactive, cesium-rich microparticles in Tokyo, 150 miles south of the accident site. When inhaled, such particles remain in human lungs, where their decay continues to release radioactivity for decades. Contaminants from future accidents will, in turn, accrete on the radioactive residues of their predecessors.
And, we might add, on the ocean floor. The Russian state-run firm Rosatom recently announced the inauguration of its first floating reactor, towed across the melting Arctic to serve a community in Siberia: yet another manifestation of how climate change favors nuclear development. Rosatom is currently negotiating contracts for reactors (floating and otherwise) in some 30 countries, from Belarus to Bangladesh, Egypt to South Africa.
Threatened, the US nuclear industry sees Russian expansion as “another reason that the United States should maintain global leadership in nuclear technology exports.” And so we hurtle forward: rolling back oversight, acceleration unchecked.
Kevin Barry in Chernobyl: ‘Misha is an example of what happens when a country is on its knees’ Irish Examiner, August 05, 2019
In 2000 the Irish Examiner sent Kevin Barry, now longlisted for the Booker Prize for his novel Night Boat to Tangier, to Chernobyl. Here we reproduce what he reported
Misha photographed by Eugene Kolzov at the No 1 orphanage in Minsk.Misha, aged seven, [on original] is the victim of not one but many sicknesses. His physical disorders, as can be plainly seen, are many and various.
But Misha is the victim of another ailment too, a kind of compassion deficiency.
Chernobyl isn’t fashionable these days, it’s been around so long now. April 26, 1986 seems a long time in the way-distant past. After the initial blurt of paranoia and charitable outreach, the fickle gaze of public interest quickly flicked from the incident at Reactor No 4 to fresher horrors.
Misha, then, has been shuffled way back in the compassion pack. He has fallen behind the other ravaged children who sombrely people the planet’s trouble spots, in places like Mozambique and Ethiopia.
He’s competing with Rwanda and Chechnya. And it’s beginning to tell Misha’s illness is a direct consequence of the Chernobyl explosion.
The radioactive danger in Belarus is not so much in the air now as in the food chain. Professor Yuri Bandashevsky, a dissident scientist, told the Irish Examiner this week that the mutations caused by radiation in children like Misha have by now entered the gene pool and thus the effects of the ‘86 explosion can stretch to infinity.
After criticising the state’s alleged misspending of research money for Chernobyl, Professor Bandashevsky recently found himself banged up in jail for five months, bound at the feet.
Which isn’t the sort of thing that bodes well for the likes of Misha. Some aid continues to filter through. This week, a convoy run by the Chernobyl Children’s Project has been on a drive through Belarus, dispensing almost £2 million in food and medicines.
One of the institutions the orphanage supports is Novinki, a children’s asylum on the outskirts of Minsk. Such is its Dickensian squalor, its actual existence was long denied by the state. This is where you’ll find little Misha.
Project leader Adi Roche says she has known the child since he was a baby, but has been stunned at his deterioration since she last visited in December.
After finding him emaciated and dying this week, the project has placed a Dublin nurse and a local Chernobyl nurse on 24-hour care alert with Misha, an attempt to make whatever is left of his life as painless as possible
“We don’t know how long Misha will live, or if he will live, but we are morally obliged to do everything in our power to attempt saving his life,” said Ms Roche last night.
“‘He is not the only child in Belarus suffering as horrifically as this. he’s just one of many.” she added. “‘These children are the victims of 14 years of neglect by the international community.”’
Many children in Belarus consigned to mental asylums have no mentaI handicap. “All orphaned children with any kind of disability are put into mental asylums if they live beyond the age of four,” she said.
Meanwhile, staffed by1,000 workers, the Chernobyl plant continues operate a couple of kilometres inside the Ukraine border.
The authorities say it will close this year. The concrete sarcophagus built to contain contamination from the reactor has 200 holes and counting.
Orphans of the nuclear age
Kevin Barry, in Chernobyl, finds a land and its people scarred by a disaster from which they may never recover.
Chernobyl at this time of year is beautiful, the borderlands of the Ukraine and Belarus a pastoral and idyllic place. Vast swardes of rich woodland are full of babbling brooks and twittering songbirds, every way you turn, there’s a postcard vista to please even the most jaded eyes.
The locals, however, are edgy. The President of Belarus, Alaksandr Lukashenko — aka ‘Batska’ (‘The Father’) — has decreed that the farmlands here–abouts are now safe to plant and he’s threatening to fly overhead and make sure the workers are toiling.
If not, he says, there will be trouble. Big trouble.
The notion of Batska in an airplane is enough to prompt sleepless nights for those who remain in the Purple Zone, the area most contaminated by the accident in 1986 at Smelter No 4 of the nuclear plant that lies inside the Ukranian border.
In a tragedy of happenstance, because there was a stiff northerly gusting that day, Belarus took the brunt of the damage and because radioactivity is most lethal when it attacks developing human systems, children have borne most of the pain.
But for these children, the most serious ailment is not the thyroid cancer or the leukaemia or the heart trouble or the kidney failure or the various disorders of colon and spleen prompted by Chernobyl.
The greatest danger is the compassion-fatigue. 1986 seems a long time ago now and the incident at Smelter No 4 is no longer swaddled in the necessary event-glamour or crisis-chatter.
When the evening news is an atrocity exhibition, when daily there are hellish dispatches from Mozambique, Ethiopia and Chechnya, the Belarussians fall ever further back in the line.
The foreign correspondents have long since moved on elsewhere. The story of a child developing thyroid cancer over a period of years doesn’t conform neatly with the sound-byte culture.
By this stage, the Belarussians have had enough. A condition of mass denial exists in the country and a native of the village Solchechy in the Purple Zone says that up to around 1993, everybody fretted and freaked out but then they decided, well, to hell with it.
“The mess got to be too much,” she says.
We don’t think about it now. Life is life and we try to get on with it.
This is easier said than done in Belarus. The country’s economy is shot — agriculture was its mainstay and since Chernobyl, the income from farming has been negligible. Almost 30% of the country’s annual turnover goes to the clean-up operation.
Belarus remains the most Soviet of states. There are thickly-piled layers bureaucracy and this tangle of demented protocol regulations and petty restrictions is amorphic, constantly shape-shifting.
a contentious report published by members of the Russian Academy of Sciences indicates that there could have been as many as 830,000 people in the Chernobyl clean-up teams. They estimated that between 112,000 and 125,000 of these – around 15% – had died by 2005. Many of the figures in the report, however, were disputed by scientists in the West, who questioned their scientific validity.
The Ukrainian authorities, however, kept a registry of their own citizens affected by the Chernobyl accident…… In Ukraine, death rates among these brave individuals has soared, rising from 3.5 to 17.5 deaths per 1,000 people between 1988 and 2012. Disability among the liquidators has also soared. …… In Belarus, 40,049 liquidators were registered to have cancers by 2008 along with a further 2,833 from Russia.
Viktor Sushko, deputy director general of the National Research Centre for Radiation Medicine (NRCRM) based in Kiev, Ukraine, describes the Chernobyl disaster as the “largest anthropogenic disaster in the history of humankind”. The NRCRM estimate around five million citizens of the former USSR, including three million in Ukraine, have suffered as a result of Chernobyl, while in Belarus around 800,000 people were registered as being affected by radiation following the disaster.
Springtime was always the busiest time of year for the women working at the wool processing plant in Chernihiv, northern Ukraine. More than 21,000 tons of wool passed through the factory from farms all across the country during the annual sheep shearing period. The April and May of 1986 were no exception.
The workers pulled 12-hour shifts as they sorted the piles of raw fleece by hand before they were washed and baled. But then the women started getting sick.
Fifty miles away was the Chernobyl nuclear power plant. On 26 April 1986 reactor number four at the power plant suffered a catastrophic explosion that exposed the core and threw clouds of radioactive material over the surrounding area as a fire burned uncontrollably. But Chernihiv was regarded to be well outside the exclusion zone that was hastily thrown up around the stricken plant and readings elsewhere in the town had shown it to have comparatively low levels of radiation.
“The area was yellow on the radiation maps which means thetown didn’t get hit very hard,” says Kate Brown, a science historian at the Massachusetts Institute of Technology (MIT). “Yet there were 298 women in this factory who were given liquidator status, which was normally reserved for those who had documented exposures during the early days of the clean-up after the accident.”
Brown uncovered the story of the Chernihiv wool workers as part of her research into the impact of the Chernobyl disaster. Her determination to unravel the true cost of the disaster has seen her travel to many parts of Ukraine, Belarus and Russia, to interview survivors, trawl through official archives and search old hospital reports.
Brown’s research, however, suggests Chernobyl has cast a far longer shadow.“When I visited the wool factory in Chernihiv, I met some of the women who were working at the time,” she says. “There were just 10 of these women still there. They told me that they were picking up bales of wool and sorting them on tables. In May 1986, the factory was getting wool that had radiation readings of up to 30Sv/hr. The bales of wool the women were carrying were like hugging an X-ray machine while it was turned on over and over again.”
Thousands of animals were slaughtered in the area around Chernobyl as it was being evacuated. Brown believes fleeces from some of these animals appear to have found their way to the factory in Chernihiv along with other contaminated wool from farms enveloped in the clouds of radioactive material that spread out across northern Ukraine.
When Brown spoke to the 10 “liquidators” at the wool factory, their stories gave a grim picture of what appears to have happened all across the region as ordinary people who had nothing to do with the clean-up of the disaster were exposed to radioactive material.
“They pointed to different parts of their bodies that had aged more than the rest and where they had health problems,” says Brown. “They knew all about which radioactive isotopes had lodged in their organs.” The other 288 women, they told her, had either died or had taken pensions for ill health.
In the weeks and months that followed the Chernobyl disaster, hundreds of thousands of firefighters, engineers, military troops, police, miners, cleaners and medical personnel were sent into the area immediately around the destroyed power plant in an effort to control the fire and core meltdown, and prevent radioactive material from spreading further into the environment.
These people – who became known as “liquidators” due to the official Soviet definition of “participant in liquidation of the Chernobyl nuclear power plant accident consequences” – were given a special status that meant they would receive benefits such as extra healthcare and payments. Official registries indicate that 600,000 people were granted liquidator status.
But a contentious report published by members of the Russian Academy of Sciences indicates that there could have been as many as 830,000 people in the Chernobyl clean-up teams. They estimated that between 112,000 and 125,000 of these – around 15% – had died by 2005. Many of the figures in the report, however, were disputed by scientists in the West, who questioned their scientific validity.
The Ukrainian authorities, however, kept a registry of their own citizens affected by the Chernobyl accident. In 2015 there were 318,988 Ukrainian clean-up workers on the database, although according to a recent report by the National Research Centre for Radiation Medicine in Ukraine, 651,453 clean-up workers were examined for radiation exposure between 2003 and 2007. A similar register in Belarus recorded 99,693 clean-up workers, while another registry including included 157,086 Russian liquidators.
In Ukraine, death rates among these brave individuals has soared, rising from 3.5 to 17.5 deaths per 1,000 people between 1988 and 2012. Disability among the liquidators has also soared. In 1988 68% of them were regarded healthy, while 26 years later just 5.5% were still healthy. Most – 63% – were reported to be suffering from cardiovascular and circulatory diseases while 13% had problems with their nervous systems. In Belarus, 40,049 liquidators were registered to have cancers by 2008 along with a further 2,833 from Russia.
The International Atomic Energy Agency, however, says that health studies on liquidators have “failed to show any direct correlation between their radiation exposure” and cancer or other disease.
Another group who bore the brunt of the radiation exposures in the hours and days after the explosion were those living in the nearby town of Pripyat and the surrounding area. It took a day and a half before the evacuation began and led to 49,614 people being evacuated. Later a further 41,986 people were evacuated from another 80 settlements in a 30km (18.7 mile) zone around the power plant, but ultimately some 200,000 people are thought to have been relocated as a result of the accident.
Some of those living closest to the power plant received internal radiation doses in their thyroid glands of up to 3.9Gy – roughly 37,000 times the dose of a chest x-ray – after breathing radioactive material and eating contaminated food. Doctors who have been studying the evacuees report that mortality among the evacuees has gradually increased, reaching a peak in 2008-2012 with 18 deaths per 1,000 people.
But this still represents a small proportion of the people affected by Chernobyl.
Brown has found evidence hidden in hospital records from around the time of the accident that show just how widespread problems were.
“In hospitals throughout the region and as far away as Moscow, people were flooding in with acute symptoms,” she says. “The accounts I have indicate at least 40,000 people were hospitalised in the summer after the accident, many of them women and children.”
Political pressure is widely thought to have led to the true picture of the problem to be suppressed by the Soviet authorities, who were keen not to lose face on the international stage. But following the collapse of the USSR and as people living in the areas that were exposed to radiation begin to present with a wide range of health problems, a far clearer picture of the toll taken by the disaster is emerging.
Viktor Sushko, deputy director general of the National Research Centre for Radiation Medicine (NRCRM) based in Kiev, Ukraine, describes the Chernobyl disaster as the “largest anthropogenic disaster in the history of humankind”. The NRCRM estimate around five million citizens of the former USSR, including three million in Ukraine, have suffered as a result of Chernobyl, while in Belarus around 800,000 people were registered as being affected by radiation following the disaster.
As of January 2018, 1.8 million people in Ukraine, including 377,589 children, had the status of victims of the disaster, according to Sushko and his colleagues. There has been a rapid increase in the number of people with disabilities among this population, rising from 40,106 in 1995 to 107,115 in 2018.
Interestingly, Sushko and his team also report that the number of Chernobyl victims in Ukraine has decreased by 657,988 since 2007 – a fall of 26%. Although they don’t explain why, this is likely to be partly due to migration as victims have left the country, reclassification of victim status and, inevitably, some deaths.
In total some 150,000sq km (57,915 sq miles) of Belarus, Russia and Ukraine are considered to be contaminated and the 4,000sq km (1,544 sq miles) exclusion zone – an area more than twice the size of London – remains virtually uninhabited. But radioactive fallout, carried by winds, scattered over much of the Northern Hemisphere. Within two days of the explosion, high levels of radiation were picked up in Sweden while contamination of plants and grasslands in Britain led to strict restrictions on the sale of lamb and other sheep products for years.
In areas of Western Europe hit by Chernobyl fallout there have also been indications that the rates of neoplasms – abnormal tissue growths that include cancers – have been higher than in areas that escaped contamination.
But Brown believes some of the actions of those attempting to deal with the aftermath of the disaster also led to contamination spreading far further than it otherwise would. In an archive in Moscow she found records that indicated that meat, milk and other produce from contaminated plants and animals were sent all over the country.
“They came up with manuals for the meat, wool and milk industries to classify produce as high, medium and low in terms of radiation,” she says. “Meat with high levels, for example, was shoved into a freezer so they could wait until it fell. Medium and low-level meat was supposed to be mixed with clean meat and turned into sausage. It was labelled as normal and sent all over the country, although they were told not to send it to Moscow.”
Brown, who has written a book about her findings called Manual for Survival: A Chernobyl Guide to the Future, also discovered similar stories of blueberries that were over the accepted radiation limit being mixed with cleaner berries so the whole batch would fall under the regulatory limit.
It meant people outside Ukraine would “wake up to a breakfast of Chernobyl blueberries” without even knowing it, she says.
Establishing the links between radiation exposure and long-term health effects, however, is a difficult task. It can take years, even decades before cancers appear and attributing them to a particular cause can be difficult.
“Genome instability represents a significant risk of cancer,” says Aleksandra Fučić, a genotoxicologist at the Institute for Medical Research and Occupational Health in Zagreb, Croatia. The daughter of a Ukrainian woman herself, she has been working with Russian scientists to study the effects of Chernobyl’s radiation on children from the region. “In Chernobyl cases, time is not healing. Time is a latency period for cancer development.”
Putting a figure on exactly how many deaths around the world may result from the Chernobyl disaster is almost impossible. But despite the grim picture much of the research paints, there are some stories of hope too.
Three engineers who volunteered to drain millions of gallons of water from tanks beneath the burning reactor in the days immediately after the explosion waded through highly radioactive water and debris to reach the release valves. Their heroics are one of the most dramatic moments in HBO’s recent dramatisation of the disaster.
Astonishingly, two of the three men are still alivedespite having minimal protection from the radiation during their mission. The third man, Borys Baranov, survived until 2005.
The Real Chernobyl: Q&A With a Radiation Exposure Expert, UCSF,
Ed note: This article considers only external radiation emitters – fails to consider internal emitters
By Nicoletta Lanese 17 July 19, The Emmy-nominated HBO mini-series “Chernobyl,” which is a dramatized account of the 1986 nuclear power plant disaster, has rekindled conversation about the accident, its subsequent cleanup and the long-term impacts on people living near the power plant.
UC San Francisco’s Lydia Zablotska, MD, PhD, grew up in Ukraine, trained as physician in Belarus, and has studied the long-term health impacts of radiation exposure on the Chernobyl cleanup workers, local children and others in the region. Her research helped uncover the connection between radiation exposure, thyroid conditions and leukemia, and remains relevant to global health today.
We talked with her about the real-life health impacts from the disaster portrayed in the HBO miniseries. The following answers have been edited for length and clarity.
What kind of radiation were people exposed to at Chernobyl?
The first responders, including firefighters and nuclear workers who tried to put out the multiple fires and prevent the explosion of other reactors at the nuclear power plant, were exposed to large doses of gamma radiation. Gamma radiation originates during the decay of radioactive isotopes of uranium or plutonium used as a nuclear fuel in nuclear power plants. As a result of decay, packets of electromagnetic radiation, which consist of high-energy photons, are emitted and could penetrate body tissues and cause damage to cells and their genetic material. Subsequently, DNA mutations could lead to the development of cancer.
The miniseries shows some workers dying instantly from acute radiation syndrome – what symptoms did they really experience?
The latest report from the United Nations Scientific Committee on the Effect of Atomic Radiation found 134 first responders who were diagnosed with acute radiation syndrome (ARS) after the Chernobyl accident. Of these, 28 died in the first four months, but not instantaneously. Then 19 more died over the next 20 years. But the majority of these survived and lived a long life after that. There were no cases of ARS among the general public living in cities and villages around the Chernobyl power plant.
Large doses of radiation could affect a number of systems in the body that are necessary for survival. Patients with ARS could develop a bone marrow syndrome, which suppresses their immunity, or a gastrointestinal syndrome, which could lead to damage to the lining of the intestines and associated infection, dehydration, and electrolyte imbalance. Then, a couple days later, the circulatory system collapses so people start having blood volume issues and so forth. The whole body is essentially collapsing.
Can those exposed to intense radiation exposure “pass on” their radioactivity to others, as the HBO show suggests?
There are types of radiation where human bodies could retain radioactive particles and remain radioactive over time, but this is not the type that was seen at Chernobyl. After gamma radiation has passed through the body, the person is no longer radioactive and can’t expose other people.
Based on what we know, at Chernobyl, there were also no effects on children who were exposed to radiation in utero.
How does radiation exposure relate to thyroid conditions?
We conducted two studies of thyroid conditions in children who lived at the time of the Chernobyl accident in affected areas in Ukraine and Belarus. We confirmed that the particular type of radiation in Chernobyl, radioactive iodine, could cause thyroid cancer. Unexpectedly, we also showed that radiation to the thyroid gland from ingesting radioactive iodine within two months after the Chernobyl accident by children and adolescents could lead to development of non-cancer thyroid diseases, such as thyroid follicular adenoma, thyroid benign nodules, and hypothyroidism.
We also showed that the youngest children were at the highest risk for developing these diseases. Children’s thyroid glands are very active and act as a sponge for iodine, because our body needs iodine. But our bodies cannot distinguish between dietary iodine, from salt or fish, and radioactive iodine. After the explosion of the nuclear reactor, parts of the core were dispersed in clouds and carried by the prevailing winds. This is how Belarus, which was in the path of winds in the first days after the accident, got really large doses. One of the most contaminated products was milk from pastured cows, mostly consumed by children.
What about leukemia?
We did a study of cleanup workers in Ukraine and confirmed that gamma radiation causes leukemia, as was found in atomic bomb survivors in Japan. Our truly unique finding was that radiation exposure can cause many types of leukemia, not just a select few. In particular, we showed that radiation doses of gamma radiation were associated with chronic lymphocytic leukemia, the most prevalent type of leukemia in adult, Caucasian men. CLL was not increased in the study of atomic bomb survivors, but as our group at UCSF reported in a later study, CLL is very rare in Japan, so this finding could have been missed. …… https://www.ucsf.edu/news/2019/07/414976/real-chernobyl-qa-radiation-exposure-expert
The grounds remain coated with plutonium, cesium, strontium and americium — radionuclides (atoms that emit radiation) that could pose potentially serious health risks to those who touch or ingest them. Some areas are more radioactive, and therefore more dangerous, than others.
“Even though the accident occurred over 33 years ago it remains one of the most radiologically contaminated places on earth.”
Chernobyl tourists should avoid plant life, and especially the depths of the forests.
Those areas were not cleaned in the aftermath of the disaster and remain highly contaminated by radiation. Research has showed that the fungus, moss and mushrooms growing there are radioactive. Eating or drinking from the area is not safe.
Those who stay on the paved pathways, which officials cleaned, are much less likely to absorb harmful toxins.
The tourists first started flocking to Chernobyl nearly 10 years ago, when fans of the video game S.T.A.L.K.E.R. wanted to see firsthand the nuclear wasteland they’d visited in virtual reality.
Next came those whose curiosity piqued when in 2016 the giant steel dome known as the New Safe Confinement was slid over the sarcophagus encasing nuclear reactor number four, which exploded in April 1986, spewed radiation across Europe and forced hundreds of thousands to flee from their homes.
Then in May, HBO’s “Chernobyl” miniseries aired, and tourism companies reported a 30 to 40 percent uptick in visitors to the Chernobyl Exclusion Zone, abandoned and eerily frozen in time.
Now the Ukrainian government — capitalizing on the macabre intrigue — has announced that Chernobyl will become an official tourist site, complete with routes, waterways, checkpoints and a “green corridor” that will place it on the map with other “dark tourism” destinations.
“We must give this territory of Ukraine a new life,” President Volodymyr Zelensky said during a visit to Chernobyl this week. “Until now, Chernobyl was a negative part of Ukraine’s brand. It’s time to change it.”
Zelensky, who was inaugurated in May, signed a decree July 10 to kickstart the Chernobyl Development Strategy, which the president hopes will bring order to the 19-mile Exclusion Zone that has become a hotbed for corruption, trespassing and theft. At the nuclear facility and in the nearby town of Pripyat, wildlife has returned and now roams freely. Flora and fauna grow up around decaying homes, playgrounds and an amusement park. Letters, dinner tables and baby dolls remain where their owners abandoned them 33 years ago.
Radioactive dust still coats it all.
“Chernobyl is a unique place on the planet where nature revives after a global man-made disaster, where there is a real ‘ghost town,’” Zelensky said during his visit. “We have to show this place to the world: scientists, ecologists, historians, tourists.”
Though exploiting a historical space like Chernobyl could infuse Ukraine’s economy with tourism dollars and motivate developers to revive the sleepy towns surrounding the “dead zone,” there are significant downsides, experts say.
[Thanks to HBO, more tourists are flocking to the eerie Chernobyl nuclear disaster site]
The grounds remain coated with plutonium, cesium, strontium and americium — radionuclides (atoms that emit radiation) that could pose potentially serious health risks to those who touch or ingest them. Some areas are more radioactive, and therefore more dangerous, than others.
“Chernobyl was the worst nuclear accident in human history,” said Jim Beasley, an associate professor at the University of Georgia who has been studying wildlife in the Exclusion Zone since 2012. “Even though the accident occurred over 33 years ago it remains one of the most radiologically contaminated places on earth.”
More than 30 people were killed in the immediate aftermath of the explosion, and officials are still debating the full extent of the longterm death toll in Ukraine and nearby countries where people grew sick with cancer and other illnesses.
The World Health Organization estimates total cancer deaths at 9,000, far less than a Belarusian study that put the death toll at 115,000, reported Reuters.
Today, radiation levels inside the Exclusion Zone vary widely from location to location, said Dr. T. Steen, who teaches microbiology and immunology at Georgetown’s School of Medicine and oversees radiation research in organisms at nuclear disaster sites. Because of that, she advises anyone visiting to be educated and cautious while inside the Exclusion Zone, and to limit time spent there.
“The longer you’re exposed, the more that future impact is,” she said.
She advises visitors to the Exclusion Zone to wear clothes and shoes they are comfortable throwing away. If they’re going to be touching or disturbing anything, she recommends a mask and gloves. Most importantly, Steen says, Chernobyl tourists should avoid plant life, and especially the depths of the forests.
Those areas were not cleaned in the aftermath of the disaster and remain highly contaminated by radiation. Research has showed that the fungus, moss and mushrooms growing there are radioactive. Eating or drinking from the area is not safe.
Those who stay on the paved pathways, which officials cleaned, are much less likely to absorb harmful toxins.
Generally speaking, Chernobyl can be safe, Steen said, “but it depends on how people behave.”
And so far, the accounts of tourists behaving badly are abundant.
Timothy Mousseau, a biologist and University of South Carolina professor, has been studying the ecological and evolutionary consequences of radioactive contaminants on wildlife and organisms at Chernobyl for 20 years. He just recently returned from his annual, month-long trip to the Exclusion Zone and said he was shocked to see 250 tourists in street clothes wandering Pripyat.
Some hopped in bumper cars at the abandoned amusement park there to take selfies.
“Part of the reason people don’t think twice about it is because there is this highly organized tourism operation,” Mousseau said. “A lot of people don’t give it a second thought.”
He is concerned that the government’s tourism campaign could only make that worse.
“The negative aspects that are being completely ignored are the health and safety issues of bringing this many people, exposing this many people to what is a small risk, albeit a significant risk, to this kind of contamination,” Mousseau said. “The more traffic there is, the most dust there is, and the dust here is contaminated.”
[We’re in the age of the overtourist. You can avoid being one of them.]
But Mousseau’s worries, and the anxieties of his colleagues, extend beyond health factors.
For decades, biologists, ecologists and medical researchers have been studying the mostly undisturbed expanse that is the Exclusion Zone. They’ve studied DNA mutations in plants and insects, birds and fish. As larger mammals, like moose, wolves and fox, have slowly re-occupied the surrounding forests, biologists have searched for clues about the ways short-term and long-term radiation exposure have altered their health.
Scientifically, there is no place on earth like Chernobyl. Beasley, who studies wolves there, calls it a “living laboratory.” An influx of humans — especially reckless ones — could destroy it.
“This is really the only accessible place on the planet where this kind of research can be conducted at a scale both spatial and temporal that allows for important scientific discovery,” Mousseau said. “Given increased use of radiation in technology and medicine, in going to Mars and space, we need to know more about radiation and its effects on biology and organisms.”
“And Chernobyl provides a unique laboratory to do this kind of research,” he said.
Tourism’s negative footprint in the Exclusion Zone is not theoretical, either.
They are leaving behind trash, rummaging through abandoned homes and buildings and, in Mousseau’s experience, stealing his research equipment. Cameras he has hidden in the depths of the most radioactive parts of the zone to capture the wildlife he studies have been vandalized or gone missing, he said.
It’s something that absolutely astounds me,” he said.
Theoretically, more government oversight at Chernobyl could help curb this kind of interference, especially if a financial investment in the zone will help preserve the ghost town there and bring in more guards and checkpoints to patrol who comes and goes.
None of that will prevent tourists from disturbing Chernobyl’s spirit.
“I think it is important to not lose sight of the fact that Chernobyl represents an area of tremendous human suffering,” Beasley said, “as hundreds of thousands of people were forever displaced from their homes or otherwise impacted by the accident.”
You’ve seen the TV series, now understand the Chernobyl catastrophe is far from over. https://www.smh.com.au/national/you-ve-seen-the-tv-series-now-understand-the-chernobyl-catastrophe-is-far-from-over-20190625-p5217u.htmlBy Helen Caldicott, 4 July 19 It is 33 years since the radioactive accident at Chernobyl. The HBO miniseries Chernobyl has re-awakened interest in this dreadful moment in history. But Chernobyl is by no means over. And with commentators once again flagging the idea of overturning Australia’s long-standing opposition to a home-grown nuclear industry – and even suggesting our own nuclear weapons – it is timely to revisit its consequences.
The Chernobyl death toll is highly contentious, from the absurdly low 31 following the initial blast trauma to 4000 (the conclusion of a joint consortium of the United Nations and the governments of Ukraine, Belarus, and Russia in 2005 and 2006) to 93,000 (Greenpeace’s prediction in 2006).
However, there is the study Chernobyl: Consequences of the Catastrophe for People and the Environment, published by the New York Academy of Sciences in 2009, which covers more than 5000 medical and epidemiological papers from the Ukraine, Russia, Europe and Britain. It was authored by three noted scientists: Russian biologist Dr Alexey Yablokov, former environmental adviser to the Russian president; Dr Alexey Nesterenko, a biologist and ecologist in Belarus; and Dr Vassili Nesterenko, a physicist and, at the time of the accident, director of the Institute of Nuclear Energy of the National Academy of Sciences of Belarus.
Their book – while the subject of both positive and negative reviews, and not peer-reviewed by Western standards – concludes some 985,000 people died prematurely, mainly of cancer, as a result of the Chernobyl accident. Despite its limitations, it “is a treasure trove of data that if taken as a whole is overwhelming”, according to the noted evolutionary biologist Tim Mousseau.
A large body of literature now records the medical impact. In Belarus and nearby regions, 90 per cent of children were once healthy, now only 20 per cent, says the Chernobyl study. A million children still live in highly radioactive areas.
The study reports ongoing abnormalities of the immune system led to increased cases of bacterial and fungal infections, chronic joint and bone pain, osteoporosis, periodontal disease and fractures. Strontium 90 and plutonium concentrate in bones and teeth.
Premature ageing with heart attacks, hypertension, strokes and type 2 diabetes and alopecia are recorded in children. Multiple endocrine abnormalities including diabetes, hypo and hyperthyroidism and Hashimoto’s disease, as well as menstrual disorders, have increased as cesium concentrates in endocrine organs and cardiac muscle.
Intellectual retardation was recorded in babies who were in utero at the time of the accident. A noted embryologist, Wladimir Werteleki, recorded high incidences of microcephaly and microphthalmia in babies and severe neural tube defects in the Polissia region of the Ukraine related to very high levels of cesium 137 and 134 in the food eaten by pregnant women. Increased incidence of congenital cataracts, retinal pathology and adult cataracts occur in many European countries.
The Chernobyl study indicated that thyroid carcinoma arose two to four years after the accident, in Belarus increasing to 7000 cases by 2000 and, despite surgery, 30 per cent were aggressive and had metastasised. Congenital thyroid cancer in newborns also was documented.
Increases in a wide range of cancers – including stomach, colon, bladder, pancreas, breast and leukemia – are still recorded in the Ukraine, Belarus, Russia, Germany, the UK, Greece, Rumania and Europe.
Many thousands of children have been born with severe teratogenic deformities and homes around the Chernobyl area house hundreds of these children.
The Chernobyl study also found that of the 830,000 mainly young men known as ‘‘liquidators’’ – who were recruited from all over the Soviet Union to help clean up the contaminated area and were exposed to massive doses of radiation –112,000 to 125,000 died within the first 19 years.
Tim Mousseau has also conducted surveys of wildlife and birds in the exclusion zones, revealing genetic and chromosomal abnormalities, sterility in male swallows, small brains, tumours, and other anatomical abnormalities.
A huge and ill-informed debate persists about how many people have died as a result of Chernobyl. Sadly, the World Health Organisation has supported the International Atomic Energy Agency, which promotes nuclear power, in the estimate of about 4000 deaths related to Chernobyl.
Much of the data is more than a decade old. There is an urgent need for further extensive epidemiological studies on the exposed populations in Russia, the Ukraine, Europe, England, Turkey and other countries, and for treatment and support to be instituted for the many thousands of victims now and in the future. Because the long-lived radiological contamination of the soil and subsequent bio-concentration of the radioactive isotopes in the food chain will continue to poison children and adults for hundreds if not thousands of years.

Secrets of Chernobyl spill out more than three decades after the nuclear disaster, By SERGEI L. LOIKOsergei.l.loiko@gmail.com, JUN 30, 2019| CHERNOBYL, UKRAINE[good photographs on original]
Seated in a jeep and clutching a screeching Geiger counter, Lt. Col. Viktor Chershnev led a convoy of 30 military trucks through the center of sleeping Kiev.
The measuring device was sounding off loudly on that night 33 years ago, not because of the convoy’s cargo — 30 antiaircraft missiles, three of them tipped with nuclear warheads — but because of where and when the post-midnight parade had kicked off: at the Chernobyl air defense missile base just three days after the explosion of a reactor at the adjacent Chernobyl nuclear power plant that had sent enough radioactivity spewing into the air that it at one point had the potential of poisoning much of Eastern Europe.
Chershnev knew that the missiles, the trucks and his crew were badly contaminated and that they should not have been ordered to drive through a city of more than 2 million people. But there was no bypass road at the time — and orders were orders. What Chershnev didn’t know in the early hours of the morning of April 30, 1986, was that a radioactive cloud had already caught up with them and blanketed the city on the eve of its annual May Day festivities.
The reaction to HBO’s recent “Chernobyl” miniseries has been almost as far-reaching as the initial tragedy and has spurred a daily line of buses packed with foreign tourists at the gate of the Chernobyl Exclusion Zone, which extends for 20 miles around the plant. But Chernobyl still boasts secrets more than three decades later, including the story of Chershnev and his charges — a saga of dysfunction and disregard for human life that lays bare conditions in the waning years of the Soviet Union.
When the red alert sounded, Chershnev, then the deputy commander and chief engineer of the Kiev Air Defense Brigade, was responsible for the readiness of weaponry and equipment at the Chernobyl antiaircraft battalion’s base in a massive in-ground bunker with 10-inch-thick, rusty metal doors.
These days, the site also features a 10-yard-long missile launcher’s towing trolley, half-buried in silver moss, the former walls of a second smaller bunker surrounded by dense pines and a vast carcass of barracks with missing floorboards, dilapidated walls and a mural of a Soviet soldier cheerfully calling upon comrades to defend the motherland.
Seventy officers and men — ill-informed, unprotected and exposed to deadly radiation — were housed at the site along with the missiles back in 1986, under orders to arduously protect and save the weapons and structures rather than themselves.
The site included the nuclear plant and the Chernobyl over-the-horizon early warning radar station, a 500-meter-long, 150-meter tall installation designed to detect strategic missiles launched from the United States. The now-rusty structure still towers over the area and is a major tourist attraction, a frightening monument to the Cold War that even the complex‘s normally fearless marauders have not attempted to cut into pieces to sell as scrap metal outside the zone, a routine business in these parts.
In the aftermath of the 1986 explosion — as the government evacuated more than 50,000 residents from the town of Pripyat, including the families of nuclear plant workers, plus more than 75,000 residents of nearby villages — the men of the Chernobyl air defense unit stayed put until they received fresh orders.
“Three days after the explosion, on April 29, I arrived at the base with 30 heavy trucks and we loaded on them 30 missiles from the storage hangars,” recalls Chershnev, who headed the evacuation effort. “Twenty-seven of them were conventional, but the other three were tactical rockets with nuclear warheads. We were to take them to a facility outside Boryspil, near Kiev.
“After that, we were ordered to go back and salvage the remaining equipment that could be dismantled.”
The men traveled — without protective gear — for 14 hours at speeds lower than 20 mph as radiation from the explosion leaked into the air.
Chershnev admits he knew the dangers but says he was a career officer and could not disobey orders………….
When Chershnev got back from that trip, he repeated the ritual of burning his uniform.
“No one in the world knows that we existed and what we went through,” he said. “And all for nothing. All so stupid and futile. We didn’t save anyone. We didn’t clean up anything.
“All those I personally know and have kept track of all these years are either badly sick like myself or dead by now. My driver who accompanied me on all the convoys was discharged and died at 28. My fellow deputy brigade commander, … who was also dealing with contaminated equipment, died [in 1995] of cancer. Warrant Officer Petro Pozyura went blind. And so on and so forth. I have a heart ailment and every year spend a couple of weeks in hospital.”
The cardiologist who has been treating Chershnev for the last few years once asked him to retrieve his Chernobyl-era medical records from the military. But Chershnev was told that the records no longer exist.
“Here I am on a pension with a monthly Chernobyl health compensation of about $11 a month,” he concluded bitterly. “It is not even enough to buy a bottle of decent vodka, let alone medicines.”
The official death toll related to the explosion is listed as 39, but out of the officially registered 3.2 million people who were exposed to radiation in Ukraine alone, 1.3 million have died in the last 33 years, said Vladimir Kobchik, a former Chernobyl cleanup worker who is now a leader of a group that aims to protect the rights of fellow survivors.
“For the last four years, the government of Ukraine has been allocating $70 million annually for the needs of the affected. That is $37 per person per year! Not a penny more! How many of those remaining 1.9 million people affected by Chernobyl are sick [and] we can’t even tell? The doctors will never tell you you are sick or dying because of radiation.”……… https://www.latimes.com/world/la-fg-ukraine-chernobyl-secrets-20190630-story.html
After the Chernobyl nuclear reactor melted down on April 26, 1986, some dogs and cats left behind survived and began to breed. More than 400 animals were spayed and neutered in the first year of the clinic’s operation at the former reactor, which ended earlier this month.
The laws governing the exclusion zone around Chernobyl strongly advise people to avoid feeding or touching the dogs, due to the risk of contamination. Not only is the dogs’ fur potentially loaded with radioactive particles, but their food and water is contaminated. The radioactive molecules they ingest may also linger in their bodies.
“We could find areas in their bones where radioisotopes had accumulated. We could survey the bones and we could see the radioactivity in them,” a Clean Futures Fund co-founder, Lucas Hixson, told Newsweek. The program funds medical treatment for locals in addition to running the spay and neuter program at the power plant and in the neighboring city.
“These dogs run through [contaminated areas] and it gets stuck on their coat and on the end of their noses and their feet.”
There are nearly 1,000 dogs in the area around the power plant. Only a few dozen cats live in the highly contaminated areas that the dogs frequent.
Hixson has been traveling to Chernobyl for about five years, initially as a radiation specialist. “I go over there expecting to do my work, and I step off the train at the power plant and there’s a dog in my face. Honestly, it was one of the last things I expected to see at Chernobyl,” he said.
To keep the veterinary hospital as free from radioactive contamination as possible, dogs that come to the facility are examined and washed down until their levels of radioactivity are deemed safe.
Despite the potential risk, Hixson said he’s continued to interact with the dogs. “There is a fair amount of handling that happens. This is a natural reaction between humans and dogs,” he said. “You can’t help yourself.”
“They’re not hazardous to your immediate health and wellbeing. But anytime you go pet the dogs, go wash your hands afterwards before you eat.”
Clean Futures Fund got approval from the Ukranian government for its operations. Other partners include SPCA International, Dogs Trust and two U.S. universities, including Worchester Polytechnic Institute and the University of South Carolina.
Hixson also noted the local workers have welcomed the team. “I remember there was a lot of skepticism when we showed up,” he said. “But after about two or three days of us catching dogs, processing them, releasing them, the attitude immediately changed,” he said. “I can’t thank them enough for everything they did.”
Even if every dog and cat in Chernobyl is sterilized and vaccinated, the wider stray dog issue in Ukraine means that more dogs could move into the contaminated area and Clean Futures Fund’s efforts could be somewhat for naught. Ultimately, Hixson would like to work with the Ukranian government on a wider rescue program to get the dogs out of the area and into homes.
He will be returning in November to measure the impact of the program, which is expected to run for five years. The next spay and neuter clinic will happen next summer.
