 note = {Soil-soil solution distribution coefficient (Kd) is an important parameter in radiation dose assessment models for the environmental transfer of radionuclides. Since Kd values vary with soil properties, development of their estimation method using some soil properties is useful. In this study, we estimated Kd values of radionickel using selected soil properties. We determined Kd values of Ni for 142 agricultural soil samples collected throughout Japan and measured such soil properties as pH, cation exchangeable capacity, exchangeable Ca, clay content, concentrations of major elements in soil, and concentrations of major elements in water soluble fractions. The relationship between Kd of Ni and each soil property was calculated using a Spearman's rank correlation test. Then, in order to estimate Kd values of Ni based on soil properties, we used the method which we developed in the previous study for strontium using multiple linear regression analysis. Our results showed that potassium concentration in soil and phosphorus concentration in water soluble fraction were the most important factors contributing to estimation of Kd values. Finally, a predictive expression including three selected variables was created to estimate Kd values of Ni. Predicted Kd values from the expression were in good agreement with observed Kd values.},
