Abstract
The main results of chemical and radiochemical characterization and fractionation of depleted uranium in soils contaminated during the Balkan conflict in 1999 are presented in the paper. Alpha-spectrometric analysis of used depleted uranium material has shown the presence of man-made radioisotopes 236U, 237Np, and 239, 240Pu traces. The fractionation in different soil types was examined by the application of a modified Tessier's five-step sequential chemical extraction procedure, specifically selective to certain physical/chemical associations. After ion-exchange-based radiochemical separation of uranium, depleted uranium is distinguished from naturally occurring uranium in extracts on the basis of the isotopic activity ratios 234U/238U and 235U/238U and particular substrates for recently present uranium material in soils are indicated.
