CESIUM-137 RETENTION AND DISTRIBUTION IN X-IRRADIATED RATS
Abstract
The influence of external ionizing radiation on the retention and distribution of the long-lived fission-product, cesium-137, in the rat were studied. An analysis of the data indicated that the increased cesium excretion in the X-irradiated rats was primarily related to the greater urine volume (diuresis accompanied by increased water intake) in these rats resulting from radiation exposure. The gastrointestinal concentrations of cesium-137 are explainable on the basis of gastric retention and delayed intestinal motility characteristic of the rat species following irradiation exposure. The liver concentration may be related to its corresponding weight increase following irradiation exposure; whereas the spleen appeared to lose weight at a greater rate than it lost cesium. The failure of bone in the irradiated rats to take up cesium to the same extent as the control rats may be due to decreased blood concentration of cesium in these rats or it may reflect direct irradiation effects on the bone.
