explain chernobyl

Chernobyl was a nuclear power plant located in the Ukrainian SSR of the Soviet Union. On April 26, 1986, one of the reactors experienced a catastrophic explosion during a routine safety test. The explosion released a large amount of radioactive material into the atmosphere, causing widespread contamination of air, water, and soil.

The disaster resulted in the evacuation and relocation of over 130,000 people from the surrounding areas, as well as an increased risk of cancer and other health issues for those who were exposed to the radiation. The disaster was the worst nuclear power plant accident in history, and it had a significant impact on nuclear safety regulations and policies around the world.
