Abstract
Experiments have been conducted to determine the sorptive characteristics of a variety of rocks and minerals with respect to several radionuclides of interest. This information will be used in the determination of the rates of radionuclide migration from nuclear waste repositories. The R/sub d/ values can be arranged according to the following inequalities: Pu greater than Cs, except for biotite; Cs greater than Sr, except for limestone; Sr greater than Tc. The exceptions are considered significant for Pu vs Cs on biotite, but not for Cs vs Sr on limestone. The low R/sub d/ values for Tc indicate that within the limits of measurement it is not sorbed under the experimental conditions studied.Keywords
