Description
As a result of investigations carried out in 1986-1993 quantitative and qualitative composition of radionuclides in the components of hydroecosystem of lake Drukshiai and their distribution in this lake are presented. Technogenic radionuclides 90Sr, 134Cs, and 137Cs and radionuclides of corrosive origin 54Mn, 60Co, 59Fe, 95Zr, 95Nb, which are characteristic products of NPP action, have been investigated. The interaction of radionuclides, hydrophytes and anthropogenic factors, the sources of radionuclides entering into lake Drukshiai from Ignalina NPP and critical zones of pollution have been established. The intensity of radionuclides accumulation levels in hydrophytes as well as in bottom sediments have been investigated. It has been determined that transformation of radionuclides chemical forms, which take place in lake Drukshiai as a result of the action of various chemical matters, changes physical and chemical properties of radioisotopes and increases their mobility in hydroecosystem.(author). 8 figs., 4 tabs., 6 refs
