The total dose from Chernobyl is estimated at 80,000 man-sieverts, or roughly 1/6 as much. [1] However, some individuals, particularly in areas adjacent the reactor, received massively higher doses. Chernobyl's radiation was detectable across Western Europe. Average doses received ranged from 0.02 mrem to 38 mrem (portions of Germany). [1]
Initially, the Soviet Union's toll of deaths directly caused by the Chernobyl disaster included only the two Chernobyl Nuclear Power Plant workers killed in the immediate aftermath of the explosion of the plant's reactor. However, by late 1986, Soviet officials updated the official count to 30, reflecting the deaths of 28 additional plant ...
Studying the populations that were exposed to radiation after the Chernobyl accident has provided data linking exposure to radiation and the future development of cancer. Cases of pediatric thyroid cancer, likely caused by absorption of Iodine-131 into the thyroid gland, increased in Ukraine and Belarus 3 to 4 years after the accident.
Radiation-induced mutations may not be the reason for the genetic differences between dog populations living near the Chernobyl nuclear power plant, according to a new study.
These scientists manually collected cold fuel rods, but great heat was still emanating from the core. Rates of radiation in different parts of the building were monitored by drilling holes into the reactor and inserting long metal detector tubes. The scientists were exposed to high levels of radiation. [54]
The Chernobyl disaster was a catastrophic nuclear disaster that occurred in the early hours of 26 April 1986, at the Chernobyl Nuclear Power Plant in Soviet Ukraine.The accident occurred when Reactor Number 4 exploded and destroyed most of the reactor building, spreading debris and radioactive material across the surrounding area, and over the following days and weeks, most of mainland Europe ...

They opposed the construction as it took place on environmental grounds, and feared that radiation could spread even more. [10] Finally on 23 May 1989, a decision was made to discontinue the construction of both reactors, writing off 500 million rubles. At the time, reactor 5 was approximately 70% completed, while reactor 6 was only 20% completed.
