Studies Concerning the Effect of Ferric Ferrocyanide,Beet Pulp,and Fluoride upon 137 Cesium Retention in the Rat

Summary

The individual and additive effects upon the elimination of ¹³⁷cesium from the body of supplementation of the diet with 1% ferric ferrocyanide (Prussian blue), 20% beet pulp, and 0.007% sodium fluoride was determined in rat muscle, femur, and carcass 30 days following a single intraperitoneal injection of the isotope. Ferric ferrocyanide showed a significant effect in reducing ¹³⁷Cs retention in each of the examined tissues. Beet pulp showed a significant effect in reducing ¹³⁷Cs retention in muscle tissue when used separately, and a greater effect when used in combination with ferric ferrocyanide and fluoride. Fluoride significantly reduced ¹³⁷Cs retention in the femur when used separately. The combination of all dietary regimens resulted in the removal of 98.7 and 97.0% of the ¹³⁷Cs in muscle and femur, respectively, and in the complete elimination of ¹³⁷Cs from the remaining carcass of the rat.
