A separation method for cesium-l37 ln biological materials is presented. The chemical steps include, phosphate elimination, ammonium phosphomolybdate precipitation and chloroplatinate precipitation. The over-all yield of cesium is over 85% and the decontamination from other fission activities is more than 10 ⁵ for cerium-144 and strontium-89. The contribution of the activities of rubidium-87 and potassium-40 is negligibly small in the determination of cesium- 137 in biological materials by beta counting.
