Summary:The sorption properties of argillaceous rock samples from the Gault, Coralian Beds, Oxford Clay and Lower Lias, obtained during a drilling program at the Harwell research site, are reported and analyzed. The partitioning of Cs, Sr and Co between rock and solid phases is shown to be a complex function of equilibration time, rock type, reaction direction and radionuclide concentration. For particular rock samples the dependence of the rock/water partition coefficient on elemental concentration of spike is generally well described for both Cs and Sr by Freundlich isotherms which, to a lesser extent, also provide a convenient, empirical description of the Co data.—Modified journal abstract
