Technogenic plutonium states in aerosols, hot particles and soils

Data on technogenic plutonium states in various natural objects, showing their multiformity, are presented. The quantitative ratios between them are defined by the source, the type of contamination, nature of sample and its physico-chemical composition. Connection between the plutonium states and its distribution by separate components of organic and inorganic part of samples under investigation is revealed. Possible composition of compounds in samples and mechanisms of plutonium inclusion into them are considered. The role of separate groups of non-isotopic carrier compounds in the geochemical features of plutonium behaviour in soils is demonstrated
