The purpose of this work is to develop a migration-dosimetric model of the formation of the irradiation of grassy plants in meadow biogeocenoses under constant radioactive fallout. The model makes it possible to calculate the volumetric activity of radionuclides in the atmospheric surface layer and the intensity of their deposition on the earth surface, the dynamics of the activity of radionuclides in the elements of meadow biogeocenoses, and the absorbed irradiation dose rate for grassy plants. Test calculations were performed for constant fallout of 131 I and 137 Cs. It is shown that during the growing season the highest accumulation of radionuclides as a result of constant fallout occurs in plant litter. During prolonged radioactive fallout, radionuclides accumulate in the sod mat; this source of radiation determines the maximum absorbed dose rate for meadow plants.

恒定放射性沉降作用下草甸生物地质群落中草类植物辐照形成的迁移-剂量学模型

这项工作的目的是开发一个迁移剂量学模型，用于在恒定放射性沉降下草甸生物地球中心草甸植物的辐照形成。该模型可以计算大气表层放射性核素的体积活度及其在地球表面的沉积强度、草甸生物地球中心元素中放射性核素的活度动力学以及草地的吸收辐射剂量率。植物。对 131 I 和 137 Cs 的恒定余量进行了测试计算。结果表明，在生长季节，植物凋落物的放射性核素积累量最高，这是持续沉降的结果。在长时间的放射性沉降过程中，放射性核素会在草垫中积聚；
