On Saturday, April 26, 1986, a catastrophic power increase occurred at the Chernobyl Nuclear Plant’s Reactor No. 4, resulting in several explosions within its core. The explosions released radioactive materials into the atmosphere, which has been widely regarded as the worst accident in the history of nuclear power. The entire town of Pripyat (population 49,360), three kilometers from the plant, was completely evacuated. In total, more than 200,000 evacuations are a result of the accident.
