Organic Factors Controlling the Excretory Pattern of Potassium-42 and Cesium-134 in Rats

Abstract
Experiments were conducted to test the influence of natural foodstuffs on the excretory pattern of cesium-134 and potassium-42. The experiments demonstrated that oat hulls, wheat bran, alfalfa meal and crude soybean oil meal influence the excretory pattern of cesium-134 and potassium-42 in rats by increasing the excretion of these nuclides in the feces as compared to their pattern of excretion when corn, cornstarch, rolled oats, wheat flour, casein, fish-meal or a purified soybean protein, are fed. This effect is not explained by the potassium, cellulose nor protein level in the natural foodstuffs fed, but appears to be an adsorption phenomenon.
