Radionuclides migration in the geosphere and their sorption on natural sorbents

Abstract

This report identifies a number of mechanisms that retard radionuclide migration, describes methods that are used to study such retardation phenomena and evaluates the extent to which this methods may be used to diagnose radionuclide migration through various types of geologic media. A qualitative, quantitative and applicable basis for ion exchange modelling in clay have provided. Caesium and strontium are taken as a reference elements, and itsK d values obtained from both batch and diffusion experiments are explained and independently predicted by the model.
