Abstract

Column experiments have been completed on the migration of 85Sr, 134Cs and 60Co through a loess layer in order to examine the migration behavior of radionuclides in an aerated soil layer. Radionuclide concentration distributions between the effluent and the soil layer were measured after the solution containing the radionuclides was introduced into the column from the top of the soil layer and Fifty liters of the underground water were introduced at a constant flow. Results indicate most of the 85Sr, 134Cs and 60Co remained attached to the soil layer, and only a small amount of radionuclide was released from the soil layer. Within the soil layer, the migration depths of three radionuclides are 85Sr > l34Cs = 60Co.
