Abstract
Summary
These experiments demonstrated that absence of dietary potassium in basal or vermieulite diet decreased urinary and fecal excretion of cesium-134, potassium-42 or rubidium-86? as well as their excretory ratio within each diet, but the pattern between the 2 diets remained relatively the same. Vermieulite, alfalfa, beet pulp, bentonite, and Amberlite IRC-50 fed to rats had the property of influencing the excretory patterns of radionuclides used. The magnitude of influence these materials exerted upon urinary and fecal excretion of these radionuclides varied between nuclides. The results in vitro demonstrated that some of these materials exhibited an affinity for specific nuclides even though these materials were in minute quantities in 0.1 N solutions of potassium chloride, hydrochloric acid, or sodium chloride.
