Chernobyl Nuclear Accident, 1986
The disastrous meltdown in the 4th reactor of the Chernobyl (Chornobyl) Atomic Electrical Station occurred on April 26th, 1986. This collection contains Ukrainian and national KGB reports, Communist Party directives, and Ukrainian Academy of Science measurements which discuss technical issues with the plant, details of the accident, and emergency responses across the republic. It shows that updates from the construction site and first few years of plant operation were dire as early as the 1970s. The collection also demonstrates that the government failed to inform the public of the true scope of radiation damage for years after the accident. Adam Higgonbotham, author of Midnight in Chernobyl, introduces parts of the collection in an essay for Sources & Methods. See also the Digital Archive collection on Ukrainian Nuclear History.
