[Prevention of accumulation of strontium-90 in the bones by fortifying the food with fish products].

The replacement of 1/5 part of the usual ration received by non-inbred white rats for fish mass containing up to 4 g/kg Ca resulted in a sharp (by 70%) reduction of Sr-90 accumulation after its oral intake. The effect is intensified in case of normalization of the basic ration in respect to Ca content, and the lowering of the isotope accumulation level in the skeleton comprises 82% as compared to the group of animals that received the Ca-deficient ration.
