В работе приводятся результаты исследования содержания радионуклида 137Cs в организме мышевидных грызунов (тушканчиков Allactaga major Kerr, Allactaga saltator Eversmann и сусликов Citellus erythrogenus Brandt), обитающих в местах испытания ядерного оружия Семипалатинского испытательного полигона и параметры перехода радионуклида 137Cs в организм исследуемых животных. Показано, что относительно повышенные значения удельных активностей радионуклида 137Cs в организме тушканчиков и сусликов отмечаются при условии их непосредственного проживания на локальных участках загрязнения. При удалении от участков загрязнения на расстояние, превышающее радиус активности животных, высоких значений удельной активности радионуклидов в животных не фиксируется. Несмотря на то, что животные обитают на участках с высокой удельной активностью радионуклидов в компонентах природной среды, экстремально высокого содержания радионуклидов в организме этих животных не отмечается.

Средние значения (AM±SD) CRmuscl радионуклида 137Cs для мышечной ткани тушканчиков прыгунов (Allactaga saltator Eversmann) составили (2.1±1.3)×10−3 (n-11), для мышечной ткани большого тушканчика (Allactaga major Kerr) – (4.7±2.7)×10−3 (n-9), для мышечной ткани суслика краснощекого (Citellus erythrogenus Brandt) – (7.0±5.6)×10−3 (n-6).

The paper presents the results of researching 137Cs radionuclide concentration in the organisms of mouse-like rodents (organisms of jerboa (Allactaga major Kerr and Allactaga saltator Eversmann) and marmots (Citellus erythrogenus Brandt)) living in the field of nuclear-weapon testing at the Semipalatinsk test site and the parameters of 137Cs radionuclide transition to organisms of studied animals. It is revealed that relatively elevated magnitudes of 137Cs activity concentration in organisms of jerboa and marmots are observed on the assumption of their residence in local contamination sites. With venturing from contamination sites at the distance exceeding the radius of animal activity, high values of radionuclides’ activity concentration are not reported. Despite the fact that animals live in the environment which components display high activity concentration of radionuclides, the extremely high concentration of radionuclide in these animals’ organisms has not identified.

The midpoint measures (AM±SD) of CRmuscl of 137Cs radionuclide for the muscle tissue of Allactaga saltator Eversmann amounted (2.1±1.3)×10−3 (n-11), for muscle tissue of Allactaga major Kerr – (4.7±2.7)×10−3 (n-9), for the muscle tissue of Citellus Erythrogenus Brandt – (7.0±5.6)×10−3 (n-6).
