The Chernobyl disaster [ 1] was a nuclear disaster . It happened on April 26, 1986 at the Chernobyl nuclear power plant near the town of Pripyat, Ukraine . At that time, Ukraine was part of the Soviet Union . The station is 110 kilometres north of the nation's capital, Kyiv .
The event was one of the worst accidents in the history of nuclear power . It was rated level 7, the most severe level, on the International Nuclear Event Scale . The only other accident with a level 7 rating is Fukushima . The RBMK reactors that were used at the plant had no containment building to keep the radiation in. Radioactive fallout drifted over parts of the western Soviet Union , Eastern Europe , Scandinavia , the United Kingdom , and the eastern United States . Large areas of Ukraine , Belarus , and Russia were badly contaminated. About 60% of the radioactive fallout landed in Belarus.[ 2] [ 3] About 360,000 people needed to be moved to other places where they could live after the accident. Many people suffered from acute radiation poisoning and long-term illnesses such as thyroid cancer .[ 4] [ 5]
