| Abstract: | There is investigated a radionuclide composition of the soil samples, selected in various parts of former Semipalatinsk Nuclear
Test Site (SNTS). The gamma-spectrometric method was used for determination of137Cs and241Am. For determination of90Sr and isotopes of plutonium a radiochemical separation was used. The results of determinations show a distinction in distribution
of radionuclides on depth for various investigated areas and for various size fractions of surface layers. The study of the
size fractions has shown an enrichment of a magnetic faction by241Am. |
