The rate of the elution of radionuclides from solidified wastes depends mainly on the dissolution at the surface of the solidified wastes and the diffusion process in the solidified body. Concerning the later process, several methods to determine the effective diffusion coefficients were reviewed and newly developed theoretically in this study. It was revealed that the coefficients representing the diffusion of radionuclides migrating in the solidified wastes can be obtained through measurements of radionuclides which were leached out from a solidified body, with limited or unlimited length, into a finite volume of water.
