Abstract
As part of a co-operative research project between the China Institute for Radiation Protection (CIRP) and the Japan Atomic Energy Research Institute (JAERI) on safety assessment method for shallow land disposal of low level radioactive wastes, an in-situ test investigating the migration of radio-nuclides {sup 60}Co, {sup 85}Sr and {sup 134}Cs in unsaturated Chinese loess under natural rainfall and artificial rainfall conditions was carried out. {sup 3}H was used for obtaining the migration velocity of moisture water in the tested zone. The result of the 2-year in-situ test indicates that the positions of peak concentration of {sup 134}Cs and {sup 60}Co in both the natural and the artificial rainfall conditions remained within 1 cm from their origins, due to the strong sorption of these two nuclides to the loess medium, while the position of the peak concentration of {sup 85}Sr in the artificial rainfall condition moved down to a depth of about 12 to 18 cm. In natural rainfall condition, there was a triple peak concentration distribution for {sup 85}Sr that might be caused by the downward and upward movements of moisture water in different seasons.
