Background and consequences

The Chernobyl liquidators were numbering between 200,000 and 800,000 according to various estimates, mobilized by Soviet authorities to contain and remediate the nuclear disaster at the Chernobyl Nuclear Power Plant following its reactor explosion on 26 April 1986.These workers, drawn primarily from military reservists, conscripts, power plant staff, and emergency teams across the USSR, undertook high-risk tasks such as extinguishing fires amid radioactive graphite, clearing contaminated debris from the reactor roof, constructing the initial concrete sarcophagus to enclose the damaged unit, decontaminating surrounding terrain, and burying radioactive materials.
