Extract

It is important to quantify the diffusion of radionuclides into pores in rock and to understand the diffusion mechanism to evaluate the migration of radionuclides in deep geological formations. The diffusivity of ions into the rock matrix is usually estimated using a theory for the diffusion in porous material, in which a proportional relationship exists between the effective diffusivity in rock and the diffusivity in the bulk of the solution. In this study, diffision of nonsorbing Γ and sorbing Sr2+ was observed simultaneously and the results were compared.
