Studies performed in the former Soviet Union were reviewed to provide interception and weathering values for radioactive particles. None of these studies were available in the English language literature before or were considered in the international reviews. The estimated mass interception fractions ranged 0.2-1.4 m kg may be explained by the size of the particles used in the research. The interrelationships among the interception fractions, plants biomass and size of radioactive particles were determined for different plants: spring and winter wheat, maize, rice, pasture and sown grass. A filtration model rather accurately approximated data for pasture grass and some other crops but does not reflect properly patterns of the interception fraction dependence on biomass for perennial sown grass. The values derived have been compared with some expected values reported by the IAEA's Handbook of parameter values for the prediction of radionuclide transfer in temperate environments (TRS 472) where possible. The information presented can be used in the current updating of parameters recommended for environmental impact assessments.
对前苏联进行的研究进行了审查，以提供放射性粒子的截留和老化值。这些研究之前均未出现在英文文献中，也未被纳入国际综述。估计的质量截留分数范围为0.2 - 1.4 m kg，这可能与研究中使用的粒子大小有关。针对不同植物（春小麦、冬小麦、玉米、水稻、牧场草和人工播种草）确定了截留分数、植物生物量和放射性粒子大小之间的相互关系。一个过滤模型相当准确地近似了牧场草和其他一些作物的数据，但没有正确反映多年生人工播种草的截留分数对生物量的依赖模式。在可能的情况下，已将得出的值与国际原子能机构《温带环境中放射性核素转移预测参数值手册》（TRS 472）报告的一些预期值进行了比较。所提供的信息可用于当前环境影响评估推荐参数的更新。
