May 8, 1986: Workers finish draining about 20,000 tons of radioactive water from the basement under the core. Over a hurried construction period of 206 days, crews erected a steel and cement sarcophagus to entomb the damaged reactor.
It is thought that the reactor site will not become habitable again for at least 20,000 years, according to a 2016 report.
About 200,000 people ('liquidators') from all over the Soviet Union were involved in the recovery and clean-up during 1986 and 1987. They received high doses of radiation, averaging around 100 millisieverts (mSv).
The initial emergency response, together with later decontamination of the environment, involved more than 500,000 personnel and cost an estimated 18 billion roubles—roughly US $68 billion in 2019, adjusted for inflation.
The loss of the four reactors amounts to perhaps $4 billion in capital costs. It is possible, however, that in time reactors 1 and 2 could be returned to service, depending on the levels of radiation in the immediate area and estimates of cleanup costs relative to new construction.
How long can you stay in the Chernobyl Exclusion Zone? There are two exclusion zones in Chernobyl; a 10km inner and 30km outer Exclusion Zone. It is safe to stay in the outer Exclusion Zone overnight.
Alexander Yuvchenko was on duty at Chernobyl's reactor number 4 the night it exploded on 26 April 1986. He is one of the few working there that night to have survived. He suffered serious burns and went through many operations to save his life, and he is still ill from the radiation.
The three men would live longer than a few weeks and none would succumb to ARS, as modern myth would have you believe. As of 2015, it was reported that two of the men were still alive and still working within the industry. The third man, Boris Baranov, passed away in 2005 of a heart attack.
Key points: At age 32, Jaan Krinal was forced to go to Chernobyl and clean the roof of the reactor. He says men were initially enthusiastic to help eliminate the radiation. One-third of the men of his town he served with in Chernobyl have died.
Yablokov, Vassily B. Nesterenko, and Alexey V. Nesterenko, Chernobyl: Consequences of the Catastrophe for People and the Environment, published by the New York Academy of Sciences, concludes that “a more realistic figure is 212,000 to 245,000 [cancer] deaths in Europe and 19,000 in the rest of the world” (p. 161).
1. Fukushima Daini Nuclear Power Plant, Japan is one of the world's most radioactive places. Fukushima is still highly radioactive today.
The official death toll directly attributed to Chernobyl that is recognized by the international community is just 31 people with the UN saying it could be 50. However, hundreds of thousands of “liquidators” were sent in to put out the fire at the nuclear power plant and clean up the Chernobyl site afterwards.
Together with Nikolai Fomin and Viktor Bryukhanov, Dyatlov was criminally charged for failure to follow safety regulations. The trial began on 6 July 1987 at the Palace of Culture in the town of Chernobyl. Only people invited by the state were allowed to witness the proceedings.
Pravyk and the firefighters who were just meters from ground zero of the worst man-made disaster in human history were so irradiated, they had to be buried in coffins made of lead and welded shut to prevent their corpses from contaminating the area for the next 26,000 years.
Underneath his portrait, the text reads: “Valery Khodemchuk's body was never recovered. He is permanently entombed under Reactor 4.” Officially, the death toll for the incident is only 31, although it is believed thousands more people have died as a result of long term radiation exposure in the years since.
Valery Alekseyevich Legasov (Russian: Валерий Алексеевич Легасов; 1 September 1936 – 27 April 1988) was a Soviet inorganic chemist and a member of the Academy of Sciences of the Soviet Union. He is primarily known for his efforts to contain the 1986 Chernobyl disaster.
Russia paid out £2.3billion to victims between 1992 and 1998 – around £4.5billion if you generously account for inflation. However, many victims of the disaster fell through the cracks without compensation, because they could not prove their health issues were related to Chernobyl.
Chernobyl had a higher death toll than Fukushima
While evaluating the human cost of a nuclear disaster is a difficult task, the scientific consensus is that Chernobyl outranks its counterparts as the most damaging nuclear accident the world has ever seen.
Today, just over 100 people remain. Once these remaining returnees pass away, no one else will be allowed to move into the exclusion zone due to the dangerous levels of radiation that still exist. Although the areas in the exclusion zone are still deemed inhabitable, many areas bordering the zone are safe to live in.
There is consensus that a total of approximately 30 people died from immediate blast trauma and acute radiation syndrome (ARS) in the seconds to months after the disaster, respectively, with 60 in total in the decades since, inclusive of later radiation induced cancer.
How large an area was affected by the radioactive fallout? Some 150,000 square kilometres in Belarus, Russia and Ukraine are contaminated and stretch northward of the plant site as far as 500 kilometres. An area spanning 30 kilometres around the plant is considered the “exclusion zone” and is essentially uninhabited.
Chernobyl animals are mutants ...
Scientists have noted significant genetic changes in organisms affected by the disaster: According to a 2011 study in Biological Conservation, Chernobyl-caused genetic mutations in plants and animals increased by a factor of 20.
Nearly 40 years later, hundreds of stray dogs roam inside the Chernobyl Exclusion Zone (CEZ), an area encompassing some 1,000 square miles around the power plant where access is restricted due to radioactive and chemical fallout from the disaster.
Valery Ilyich Khodemchuk (Ukrainian: Валерій Ілліч Ходемчук; Russian: Валерий Ильич Ходемчук; 24 March 1951 – 26 April 1986) was a Soviet engineer who was the night shift circulating pump operator at the Chernobyl power plant and was the first victim of the Chernobyl disaster.
