About :

The Chernobyl nuclear disaster occurred 37 years ago, on April 26, 1986 at 01:23, due to a failed safety test of reactor number 4 of the nuclear power plant in the municipality of Pripyat, in present-day Ukraine, about 100 km from Kiev. Chernobyl is the most serious nuclear accident in history, and the causes of this catastrophe are a design error of the reactor and human error. The explosion of the reactor of the Chernobyl plant caused between 200 thousand and 350 thousand displaced people, 64 deaths directly linked to the accident and thousands of cases of cancer patients in the months and years that followed, as reported in the Chernobyl Forum report drawn up by UN agencies.
