Influence of Dietary Potassium and Sodium on Cesium-134 and Potassium-42 Excretion in Sheep

The Removal and/or Reduction of Radionuclides in the Food Chain

“…Cesium urinary and fecal excretion was enhanced when dietary K and Na intake was increased in rats, swine, rabbits, and sheep. In sheep, total 134CS excretion increased from 12% in a diet deficient in Na and K to 52% when the dietary K content was increased to 2.5% (55). This observation was later confirmed in the rat by other laboratories.…”

Artificial environmental radionuclides in Europe and methods of lowering their foodstuff contamination – a review

“…Administration of potassium in the diet caused an increase in radiocaesium excretion (Mraz et al 1958;Mraz 1959;Johnson et al 1968), while the administration of stable caesium was not efficient (Oughton et al 1989;Rundo 1964). Different complexes or chelating additives are used successfully, with the ability to absorb and/or to bind radionuclides forming chemical compounds not absorbed by the digestive tract but easily excreted from the body (Giese 1988;Giese 1989;Pöschl and Baláš 1999;Pöschl and Řezáč 2004).…”

Vertebrate Radiobiology: Metabolism of Internal Emitters

“…They found no evidence in any tissue for cesium retention with a biological half life longer than 17 days. The effects of dietary constituents, particularly other alkali metals and various adsorptive agents, in laboratory and farm animals have been reported by Mraz, Patrick et al [see (93)]. While there are substantial interactions between certain of the alkali metals in their metabolic behavior, the chances of employing these characteristics in any practical scheme for dietary control of radiocesium dep osition seem very remote.…”
