Investigations of Soil Radionuclide Activities

该项目的目标是确定与放射性核素在土壤中的迁移和/或保留有关的重要土壤风化过程的特征，确定各种土壤成分在提供放射性核素聚集地方面的作用，并编制辐射潜力图，以加强现有的土壤和地质图。这项工作将分两个阶段完成：将土壤性质与放射性水平联系起来的实地研究，以及模拟属于具有代表性的放射性水平组的土壤材料风化的实验室淋滤实验。

The objectives of this project are to characterize the important soil weathering processes associated with the transport and/or retention of radionuclides in soils, to determine the role of various soil constituents in providing sites for radionuclide accumulation, and to develop radiation potential maps which augment existing soil and geological maps. The work will be accomplished in two phases: a field study relating soil properties to radioactivity levels, and a laboratory leaching experiment which simulates weathering of soil materials belonging to a representative range of radioactivity-level groups.
