Определены минимальные и максимальные значения удельной активности 137Cs, 90Sr, 241Am, 239+240Pu в исследуемых почвах, а также в минеральной и органической составляющей подстилки. Сформированы ряды  радионуклидов по их способности к накоплению в верхнем почвенном слое и компонентах лесной подстилки. Установлена зависимость между содержанием радионуклидов 137Cs, 90Sr, 241Am, 239+240Pu в компонентах лесной подстилки и ее мощностью.</p></abstract><trans-abstract xml:lang="en"><p>The paper provides results of research of concentration and distribution of artificial radionuclides in the components of forest litter and in the top soil layer of the pine forest of Priirtyshie long after nuclear tests at the territory of Semipalatinsk Test Site (the STS). Minimum and maximum values of specific activity were determined for 137Cs, 90Sr, 241Am, 239+240Pu in the soils researched as well as in mineral and organic components of litter. Series of radionuclides were formed depending on their ability to be accumulated in the top layer of soil and in the components of forest litter. Dependence between concentrations of 137Cs, 90Sr, 241Am, 239+240Pu in the litter and its thickness was determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиоэкология</kwd><kwd>Семипалатинский испытательный полигон (СИП)</kwd><kwd>искусственные радионуклиды (137Cs</kwd><kwd>90Sr</kwd><kwd>241Am</kwd><kwd>239+240Pu)</kwd><kwd>лесная экосистема</kwd><kwd>лесная подстилка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radioecology</kwd><kwd>Semipalatinsk Test Site (the STS)</kwd><kwd>artificial radionuclides (137Cs</kwd><kwd>90Sr</kwd><kwd>241Am</kwd><kwd>239+240Pu)</kwd><kwd>forest ecosystem</kwd><kwd>forest litter</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Krasnov V.P., Orlov A.A., Buzun V.O. et al.
