The paper reports on the study of artificial radionuclide accumulation in agricultural crops grown at the territory with high concentration of radionuclides, and first of all - with high concentration of transuranium elements. As a result of this work, peculiarities of accumulation and distribution of artificial radionuclides in the vegetative and generative organs of the studied plants have been revealed. Basic accumulation factors have been found for (137)Cs, (90)Sr, (239+240)Pu, and (241)Am in agricultural products. Accumulation factor dependence on type of planting was found for the investigated types of plants. It has been found that the vegetative organs accumulate radionuclides most of all.
该论文报道了对生长在放射性核素浓度高的地区，尤其是超铀元素浓度高的地区的农作物中人工放射性核素积累情况的研究。这项工作的结果揭示了人工放射性核素在被研究植物的营养器官和生殖器官中的积累及分布特性。已发现了农产品中（137）铯、（90）锶、（239+240）钚和（241）镅的基本积累系数。对于所研究的植物类型，发现积累系数与种植类型有关。已发现营养器官积累放射性核素最多。
