Abstract

Radiation doses to the population and the biota components in the area of the former uranium mining company LPO “Almaz” are estimated. Maximally exposed is soil mesofauna and aquatic organisms. The contribution of internal exposure to the total dose burden for natural objects is greater than 90 %. Scenarios were developed to assess exposure doses to the population varying in the ways of dose formation. As a result, the calculations revealed that there is a likelihood of exceeding the permissible level of exposure. The main dose-forming radionuclides are 210Po, 210Pb, 226Ra and 230Th.

Key words
Natural radionuclides, galleries, biota, radiation exposure, external and internal exposure.
