One of the most polluted body of water was cooling (WC) accident. The nature of radioactive contamination of WC is rather complicated, due to "spotting" Fallout, finding different forms of radionuclides ("hot" particles with different chemical composition, shape and structure, solid and liquid aerosol), and additional radionuclides, caused by carrying out decontamination work, spring floods and wind pyloperenesennyam. On the example of WC was found significant increase of Cs-137 in water, which begins in May and reaches its peak in August and September. Then there is a decrease in the content of this radionuclide. It is believed that it caused remobilizatsiyeyu Cs-137 in water from the sediment caused by the activity of microorganisms, which largely depends on water temperature and intensified in the summer. Depending on supplies of fish to different environmental groups, the highest content of Cs-137 in fish muscle Chernobyl cooling pond recorded in the period from early spring until autumn. During the reporting period continued study of the dynamics of radionuclides of Chernobyl origin in different sites of forest ecosystems in the grounds of the Chernobyl exclusion zone and a "southern trail". Radionuclides, which contributes up to 100 percent in total activity of the investigated components of forest biocenoses (fruiting bodies hrybivmakromitsetiv) is a long existing radionuclide Cs - Cs-137. During the reporting period the content of Cs-137 in mushrooms in the grounds of the Kyiv region and the exclusion zone virtually unchanged.
