对从前塞米巴拉金斯克核试验场 (SNTS) 的各个部分选取的土壤样本的放射性核素成分进行了研究。采用γ能谱法测定137Cs和241Am。为了测定 90 Sr 和钚同位素，使用放射化学分离。测定结果表明，不同研究区域和表层不同尺寸部分的放射性核素在深度上的分布存在差异。对尺寸分数的研究表明，241Am 富集了磁性部分。
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.
