Decontamination efficiency of zeolite and alginate in reducing the radiostrontium transfer to tissues and organs of rats after repeated administration was evaluated. In the group fed the alginate-enriched chow, the ⁹⁰Sr were significantly lower that those recorded in the control animals during the entire study. The highest decontamination efficiency was recorded at third measurement time point. Generally, zeolite was less effective decontamination agent than alginate. Moreover, in some rat organs (kidneys, spleen and testes) the strontium-90 levels were even significantly higher than those in the control rats. So, presently alginate seems to be the most efficient decontamination agent in reducing the radiostrontium transfer to tissues and organs of rats.
