Description	The uptake o technetium on bentonite materials has been studied from the point of view of characterization of long-term radioactive elements behavior in nuclear waste repository. Bentonite R (locality Rokle, Czech Republic) and two types of model groundwater (granitic and bentonite) were selected for the sorption experiments. It is generally known that bentonite materials show an excellent cation-exchange capacity and, on the other hand, a poor uptake of anions. Technetium occurs under aerobic conditions in its most stable oxidation state (+VII) as pertechnetate, which makes a question of its sorption on bentonites more complex, when compared with e.g. Cs+ or Sr2+. To increase the Kd balues for technetium sorption on bentonites, it is necessary to carry out the experiments under anaerobic conditions in the presence of reducing agent, which es capable to lower the oxidation state of technecium which enables its successfull immobilization. The aim of our research has been to find out the conditions suit The uptake o technetium on bentonite materials has been studied from the point of view of characterization of long-term radioactive elements behavior in nuclear waste repository.
