In summer 2009, the level of pathology of erythrocytes was assessed in the peripheral blood of roach (Rutilus rutilus L.) from the reservoirs for water-storage of low level radioactive waste of PA "Mayak". Roach from the Shershny reservoir and the Buffer reservoir (Chelyabinsk region) was used as a control. Radionuclide maintenance in water, sediment, and roach was determined and dose rates for the roach were calculated using the software package ERICA Assessment Tool 1.0 May 2009. It is revealed that chronic radiation exposure with the dose rates in the range from 0.8 up to 19 mGy/d leads to a twofold increase in the frequency of erythrocytes with micronuclei in peripheral blood, dose-dependent increase in the frequency of red blood cells with the nuclear pyknosis and causes no significant increase in the level oferythrocyte amitosis. It is suggested that the frequency rate of apoptosis in peripheral blood erythrocytes of the fish could be used in the biological monitoring of contaminated aquatic ecosystems.
