Abstract
To establish a safety evaluation methodology for shallow land disposal of low level radioactive waste, cooperative research had been undertaken between Japan Atomic Energy Research Institute(JAERI) and China Institute for Radiation Protection(CIRP). Field tests on migration of {sup 3}H, {sup 60}Co, {sup 134}Cs and {sup 85}Sr were conducted during under both artificial and natural rain conditions, and laboratory experiments and site characteristics investigations were conducted to obtain information on migration parameters for evaluation of the radionuclide migration. Migration behavior of the radionuclides under the artificial rain condition, in which behavior of infiltrating water was kept at a constant, agreed well with that estimated by migration parameters obtained in the laboratory experiments. Under artificial rain condition, the peak position of {sup 85}Sr distribution moved to 10 cm downward from the start tracing position, while the almost part of {sup 60}Co and {sup 134}Cs did not move. Under the natural rain condition, all the peak positions of three radionuclides did not move. These results suggested that the migration of {sup 60}Co, {sup 134}Cs and {sup 85}Sr was significantly retarded by the loess medium. The {sup 85}Sr migration under artificial rain condition was well described by the equilibrium sorption model using distribution coefficient.
