In this case, β- and γ -irradiation of 137Cs and β-irradiation of 90Sr were determined in the water, bottom sediments, and higher aquatic plants. In addition, β-irradiation of the incorporated radionuclide was also determined. Fish embryos occurring on different substrata and at different temperatures were investigated. It has been found that the dose rate of fish embryos of the Kiev Reservoir accounts for 183−8000 nG/day. The principle of ecological standardization of radionuclide contamination of bottom sediments of fresh water bodies was put forward on the basis of the performed calculations. %8 2014-01-27
