A method for a simultaneous decrease of strontium, caesium and iodine retention after oral exposure in rats

Measurements were made of the combined action in rats of sodium alginate, iron (111) ferrocyanide and sodium perchlorate as dietary additives, and of the effect of each of them on the separate absorption and retention of 85Sr, 137Cs and 131I. Food consumption and body weight were practically unchanged by the additives, and there was no appreciable interference between the additives in producing substantial reduction in the retention of oral doses of 85Sr, 137Cs and 131I. The body burden of these three important fission products could be reduced by this single remedial procedure. (U.K.)
