SPECIATION OF TECHNOGENIC PLUTONIUM IN AEROSOLS, HOT PARTICLES, AND SOILS

Speciation of technogenic plutonium in various environmental objects i s examined. The plutonium distribution throughout diverse forms of its occurrence is controlled by its origin and the nature and physicochem ical characteristics of the sample. The speciation of plutonium correl ates with its distribution throughout the organic and mineral fraction s of test samples. The mechanisms of Pu attachment to the mineral frac tion and possible composition of compounds formed in it, and also the contribution of separate groups of compounds of nonisotopic carriers i n geochemical behavior of Pu in soils are discussed.
