On this day in 1986 the world’s worst nuclear power plant accident occured at the Chernobyl plant in the Soviet Union. An explosion blew the lid off a reactor vessel and fifty tons of radioactive material billowed into the atmosphere, thirty-two people died within days, thousands more in the long run and millions of acres of forest and farmland were contaminated. Chernobyl is located in the Ukraine. There have been two nuclear accidents that rated a 7 on the International Nuclear Event Scale- the other 7 was in 2011 at the Fukushima Daiichi disaster. The city of Pripyat had to be abandoned. It is a ghost town today.
