On April 26 in 1986, the world’s worst nuclear accident to date occurs near Kiev in Ukraine. The full toll from this disaster is still being tallied, but experts believe that thousands of people died and as many as 70,000 suffered severe poisoning. In addition, a large area of land may not be livable for as much as 150 years. The 18-mile radius around the plant was home to almost 150,000 people who had to be permanently relocated. - This Day in History
