An integrated modelling and experimental approach related to the quantification of the sorption of radionuclides onto geological materials is described. The primary role of the experimental work is to provide data for repository safety-assessment studies. Modelling is carried out to aid interpretation of these data. Results from experiments of sorption of three radionuclides onto various rock types are presented in this paper, and using the modelling, explanations for variations in measured sorption values with physical and chemical parameters are suggested.
