A Method of Radiochemical Determination of Cesium-137 in Human Urine
Analytical method to determine cesium-137 in human urine was studied. Cesium-137 with cesium-carrier was adsorbed on solid ammonium molybdophosphate in acidified urine. The precipitate was dissolved with alkaline solution, and cesium was separated with a column of phenol-sulfonic acid type cation exchange resin. Cesium was finally precipitated as cesium perchlorate and its BETA activity was measured with an anticoincidence lowbackground Geiger-Muller counter. A few mu mu C of cesium137 in a sample solution could be determined by the method. The method was used in a routine survey program of cesium-137 contamination of human urine since 1961. This method can also be applied to the determination of cesium-137 in natural waters. (auth)
