The principle advantages of the method are, (1) equilibration of cerium carrier and activity in the initial step of the procedure, (2) provision for the determination of strontium-90 and cesium-137 in vegetation and strontium-90 and normal cerium in soil. The results of measurements on fourteen wheat samples col l...
