| 内容記述 | The soil-soil solution distribution coefficient (Kd) is one of the most important parameters required by the models used for radioactive waste disposal environmental impact assessment. The models are generally based on the assumption that Kd is independent of the element concentration in soil solution. However, at high soil solution concentrations, this assumption is not valid. Since the sorption of most radionuclides in soil is influenced by their stable isotope concentrations, it is necessary to consider if the range in the naturally occurring stable isotope concentrations in the soil solution is within the range over which Kd is valid. The objective of this study was to determine if the Kd for nickel (Ni) can be assumed to be constant over the ranges of stable Ni concentration in five main Japanese agricultural soil types.To obtain Ni sorption isotherms for five Japanese soils, two types of batch sorption tests were carried out using radioactive 63Ni as a tracer. | |||||
