Kravets' O. Radioecological aspects of formation of radionuclide flows into "Soil-Plant" system "

Dissertation is devoted to the investigation of the effects of soil-plant relationship and their influence on the intensity's radionuclide absorption by plant being a beginning link of food chains and estimation of consequences of use of the agrocenosеs polluted with 137Cs and 90Sr. It was shown that root excretion of higher plant increase the rate of destruction of insoluble forms of radionuclides It was demonstrated that this ability of alive organisms was connected with genetic property as well as functional state. Physiological nature of plant attractive ability and "capacity" of radionuclides accumulation had been investigated. The three-module ecological model of assessment of radiological consequences (EMARC) of use of polluted agrocenoses had been developed. Estimations were conducted for agrocenosese of Northern Ukraine with six soil types.
