He exposed himself to large doses of radiation, being the head of the government commission.
He died in 1990 at age 70, and it's not clear if he died of radiation or not, given that he ordered the construction of a new town in the highly contaminated area. In a secret 1988 decree that he helped form, Soviet doctors could not cite radiation as a cause of death or illness.
