Age Peculiarities of the Accumulation of ¹³⁷Cs by Freshwater Bivalvia in the Cooling Pond of the Chernobyl NPS and in the Pripyat River

ABSTRACT

The age peculiarities of the accumulation of ¹³⁷Cs in soft tissues of Bivalvia belonging to various dimensional groups registered in water bodies of the exclusion zone of the Chernobyl NPS, including the cooling pond of the Chernobyl NPS and the Pripyat river, were studied. It has been found that the content of ¹³⁷Cs decreases in proportion to the increase in the linear dimensions of specimens. This relationship may be described by the equation A = aL^-1.54±0.20. It is believed that the distinctions in the ration of mollusks, and also various intensities of the processes of metabolism in specimens differing in their dimensions, are responsible for this phenomenon.
