[Functional-ecological and age-specific regularities in radionuclide concentration in freshwater molluscs from the Chernobyl Atomic Energy Station exclusion zone].

The results of the studies on 90Sr and 137Cs content in the tissues of bivalve and gastropod mollusks of water basins in the exclusion zone of the Chernobyl NPP have been analyzed. The dependence of radionuclide accumulation factors on the peculiarities of morphological structure, functional ecology and nutrition type was found. The age dynamics of 137Cs content in some species of Gastropoda was studied.
