Belyayev V. Accumulation and elimination of Cesium-137 from the organism of the hydrobionts

The peculiarities of accumulation of radionuclides of hydrobionts of aquatic ecosystems of Zhytomyr and Rivno region and Chernobyl exclusion zone were analyzed. Method of determination parameter of elimination of gamma- radionuclides from a live fish was worked. The peculiarities of accumulation and elimination of 137Cs in carp from the cooling pond of the Chernobyl NPP were analyzed. The peculiarities of elimination of 137Cs in carp and goldfish, after receiving an acute contamination, were analyzed. 137Cs excretion following K+ addition in the diet to carp are researched. Increasing of K+ content in the first injection relative contribution of the shortest component increases. The change of 137Cs content in organs and tissues of fish, after receiving an acute contamination, was studied.
