Estimates are presented of the radiation doses due to plutonium received by people living in the areas of Russia contaminated as a result of the accident at the Chernobyl nuclear power station.
This is based on model representations of the migration of the nuclides in the « soil-man » system.
The effective dose (E) has been examined for the whole population and for the critical group of inhabitants (agricultural machine operators) in relation to the inhalation of resuspended radionuclides.
The calculated irradiation doses were supplemented by values obtained from the determination of the concentration of plutonium isotopes in the main organs and tissues of people living in contaminated areas of the Bryansk repion.
An analysis of autopsy data gives an unambiguous indication of the existence of « Chernobyl additions » to the plutonium concentration burden of the inhabitants.
It was established that the effective dose values vary within fairly wide limits in different population groups.
