The work provides results of complex research of the levels and character of the distribution of radionuclide contamination in the system of "bottom sediments - water - plants" of technogenic water bodies at the Semipalatinsk Test Site (STS). The objects of research were craters formed as a result of nuclear tests, filled with water, located at the test sites "Experimental Field", "Balapan", "Telkem" and "Sary-Uzen". Samples of sediments, soils, waters, aquatic, semiaquatic and waterside plants were taken for determination of 241Am, 137Cs, 90Sr, 239+240Pu concentration for this research. As the result of experiments distribution coefficient (Kd) for sediments and water and concentration ratio (FV) for aquatic and semiaquatic plants and sediments, waterside plants and soils were calculated. Based on the obtained results comparative analysis of the redistribution of radionuclide contamination in technogenic water bodies at the STS was done.
