Jun 13, 2013 · On 26 April 1986, the Number Four reactor at the Chornobyl Nuclear Power Plant in what then was the Soviet Union during improper testing at low-power, resulted in loss of control that led to an explosion and fire that demolished the reactor building and released large amounts of radiation into the atmosphere.

There were over 100 radioactive elements released into the atmosphere when Chernobyl’s fourth reactor exploded. Most of these were short lived and decayed (reduced in radioactivity) very quickly. Iodine, strontium and caesium were the most dangerous of the elements released, and have half-lives of 8 days, 29 years, and 30 years respectively.

The post-Chernobyl outlook for nuclear power A view on responses to the accident from an international perspective by Dr Hans Blix In 1979, the Three Mile Island (TMI) accident had a heavy impact on nuclear power. It made many people sceptical of— and some even hateful — toward it. There is no doubt that the accident slowed down growth in
