The sorption characteristics of {sup 137}Cs and {sup 90}Sr on soil matrix have been studied by the batch technique. The sorption coefficients (K{sub d}) and retardation factor (R{sub f}) have been determined for these radionuclides on soil matrices collected from a number of locations in and around the proposed site for shallow land disposal of low-level radioactive wastes at the Atomic Energy Research Establishment (AERE) campus, Savar. The K{sub d} values varied from 1,278 to 2,156 ml/g for {sup 137}Cs and from 350 to 640 ml/g for {sup 90}Sr. The retardation factors varied from 1,709 to 3,072 for {sup 137}Cs and from 409 to 903 for {sub 90}Sr. The results obtained indicated that the AERE soils have good sorption capacity for {sup 137}Cs and {sup 90}Sr radionuclides. These data could be used in radionuclides transport and safety assessment models.
