Effect of sodium and potassium supplementation on accumulation and excretion of radiocaesium in reindeer
We tested the effect of sodium and potassium supplementation on radiocaesium excretion and accumulation in reindeer eating lichens (winter diet). Nine reindeer were divided into 3 groups of 3 animals. One group was daily given 0.35 M KC1, one was given 0.35 M NaCl (both dissolved in 1 1 water), and...
