    Geochemical features of Cs, Sr, U, Pu behaviour in the zone of their hypergenesis are presented in the article. Necessary conditions for these elements filtration on the natural geochemical barriers are shown. Data of radionuclide composition of water for five years of observation in << Ryzhiy Les >> and dissolved forms of radionuclides are described. Geologic and hydrogeologic conditions of the Chernobyl NPP site are shortly characterized. Radionuclide composition in the ground water of contaminated water pools is analyzed. It is proposed to cover by the law all {alpha}-elements (Pu, Am, Np) and not only plutonium as it currently takes place.
