title: [Evaluation of radiocesium retention in selected tissues and internal organs of the rat].
abstract: The specific activity of radiocesium in the liver, brain, heart and thigh muscle was measured during 14 days after a single intragastric administration of 137CsCl. The highest concentrations of radiocesium in the heart and liver were obtained quickly - 3 hours after administration. Cupric ferrocyanide, an ion exchanger displaying strong affinity to the cesium ion, was used to reduce the concentration of this radionuclide in the above-mentioned organs, there was a substantial reduction of cesium retention in the heart and liver indicating that the bonds between the cesium ion and proteins in the heart and liver are weak. Concentrations of radiocesium in the high muscle and brain were highest after 2 days, the application of ion exchanger led to the higher retention of the investigated radionuclide, explainable by the presence of stronger bonds between cesium and proteins in the thigh muscle and brain.
