Amounts of particulate radionuclides and their reaction constants in radionuclide migration test using undisturbed samples of aerated sandy soil layers

Technical Report:

Abstract

The amounts and the reaction constants of particulate {sup 60}Co and {sup 137}Cs were estimated from the results of radionuclide migration tests for undisturbed samples of an aerated sandy soil layer by using inverse analysis. It was found that the amount of each particulate radionuclide was less than a few percents of the total amount of the introduced radionuclide and independent of water flow velocity. In the case of {sup 60}Co, the reaction constant of adsorption was 10{sup -4}-10{sup -3} (ml/g{center_dot}min) and that of desorption was 10{sup -5}-10{sup -4} (1/min). These values are corresponding to the distribution coefficient of several 10`s (ml/g), when the adsorption-desorption reaction was reached to equilibrium. In the case of {sup 137}Cs, the reaction constant of capture was 10{sup -4}-10{sup -3} (ml/g{center_dot}min) and nearly the same as that of the adsorption of {sup 60}Co. The dependence of the reaction constant on water flow velocity was found clearly in each radionuclide and the reaction constant of desorption of {sup 60}Co depended upon the flow velocity strongly.
