The Role of Phytoplankton in Migration of Radionuclides in Water Bodies Differing in the Level of Radioactive Contamination

It has been found that after the accident at the Chernobyl Nuclear Power Station phytoplankton plays a leading part in migration of strontium-90 and cesium-137 between abiotic and biotic components of aquatic ecosystems in continental water bodies of Ukraine differing in the level of radioactive contamination.
Quantitative characteristics of migration of radionuclides in the system "water-phytoplankton" are determined by intensity of the processes of production in algal communities.
