Radioecological monitoring of water systems of various regions of the Republic of Belarus affected by the accident at Chernobyl NPP

摘要

The work is aimed at studying radionuclide contamination of water system components in order to evaluate the consequences of the Chernobyl disaster for water resources of the Republic of Belarus. As a result of the studies there have been elicited peculiarities in the dynamics of the radioecological situation and roles of separate components in the overall balance of radioactive contamination of water systems in the Eastern-Belarusian province. The data on the radionuclide content in water and water vegetation allow an assessment of the danger of these components getting into human body directly, or indirectly through food chains. The established relationships in radionuclide distribution among components of the ecosystems studied can be applied to other systems of lentic and lotic types (lakes, big ponds, rivers) used for public needs.
