FORMS OF PLUTONIUM EXISTENCE AND MIGRATION IN SOILS
The investigation objects are the plutonium, soils, grasses and hot particles. The aim is to study the special geochemical features of the plutonium behaviour in the soils of the Russia's steppe and partially-wooded steppe zones in the regions of arranging enterprises of the nuclear-fuel cycle. The regularities of the plutonium behaviour in the different type soils have been determined; the geochemical barriers of accumulating plutonium within the limits of the soil profile have been revealed. The forms of the plutonium existence in the soils depending on the sources of its reception have been determined; the hypothesis about mechanisms of its transfer in the soils has been stated. The radiochemical methods for detection of the plutonium in the soil-vegetable cover have been developed. The investigation results on the existence forms and behaviour regularities of plutonium in the land ecosystems can be used at development of the measures on the rehabilitation of the contaminated territories. The radiochemical methods for detection of the plutonium in the environment samples have been introduced. The methods have been introduced at the scientific organizations occupying with the solution of the ecological problemsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
