Radioactivity was an excellent discovery. Radioactivity is useful..but there is a saying called there are two sides of a coin.. I know everybody should be aware of Chernobyl. Chernobyl is one of worst nuclear power plant accident in History.
Well, in 1984, an accident at Chernobyl nuclear power plant. One of the reactor exploded and further explosions sent fumes into the atmosphere. It was a highly reactive fallout and spread over an extensive area. The effect was more than 40 times as of that of Hiroshima. The fumes distributed over parts of Western Soviet Union, Western and Eastern Europe and Eastern North America. Russia was badly contaminated with radioactive rays. There was evacuation and resettlement of more than 300,000 people.
This accident raised great concerns about the safety of Soviet nuclear power industry. Now-indepedent countries like Russia, Ukraine and also Belarus have been affected with continuing, rapid and substantial decontamination. Infact, it is quite difficult to estimate the number deaths caused. It was indeed difficult to track down victims. Soviet Authorities had to forbade doctors to mention "radiation", on death certificates. However, the effect can still be felt in areas around the reactor.
