The main feature of bentonite clays is a high sorption ability to various radionuclides. Sorption of 90Sr and 137Cs by natural and mono-cationic (Na, Mg, Ca) species of Taganskoe (Kazakhstan) bentonite clays is reported. The sorption index (S) for 90Sr on natural as well as Na-, Mg-bentonite species samples exceeds 95%, for the Ca-form this index is lower (84%). The sorption index with respect to 137Cs is up to 80% for the natural clay and Mg-, Ca-species samples, whereas it is about 73% for the Na-form.
