About: Individual involvement in the Chernobyl disaster

The Chernobyl disaster was a catastrophic nuclear disaster that occurred in the early hours of 26 April 1986, at the Chernobyl Nuclear Power Plant in Soviet Ukraine. The accident occurred when Reactor Number 4 exploded and destroyed most of the reactor building, spreading debris and radioactive material across the surrounding area, and over the following days and weeks, most of mainland Europe was contaminated with radionuclides that emitted dangerous amounts of ionising radiation. On the night of April 25th and the early hours of April 26th, there had been 160 personnel on duty across the facility, while 300 more workers were on site at the building site of reactors 5 and 6.
