A reactor at the Chernobyl power station exploded in April 1986, sending a radioactive plume across the Europe and leaving nearly 50,000 square kilometers of land contaminated. At least 31 people were killed immediately afterwards and more than 600,000 were reportedly exposed to high radiation levels. /VCG Photo
