Separation of Radioactive Cesium in Biological Materials
View through CrossRef
Abstract
A simple and rapid separation method for cesium-137 in biological materials has been presented. It is composed of three steps, 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 105 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.
