Notes from a discussion among Soviet military leaders concerning the risk of contamination during the Totskoye nuclear exercise.

Petrov details efforts to limit contamination from the Totskoye nuclear exercise in 1954.

References, apparently from an index, to different Soviet reports: the first from 1950, on atomic attacks, and the second from 1980, on the Solidarity movement in Poland.

The Soviet Minister of Power and Electrification reports on an explosion and fire at the Chernobyl Atomic Power Station in Ukraine. The Soviet Ministry of Heath has determined that "it is not required to take special measures, including the evacuation of the population from the city."

Yuri Andropov, then Chairman of the KGB, reports concerns about the Chernobyl nuclear plant. Serious flaws in the construction "might lead to failures and accidents."
