Quantitative analysis of tracer elements by radiometric titration is found to have the advantage that the radioactivity is not brought into the tracer element by the addition of radioactive indicator but is originally in the element to be determined. Furthermore, it is possible by titration to measure the radioactivity of the tracer while determining the weight. Estimation of specific activities of Zn/sup 65/ and U/sup 237/ by titration is presented. Total zinc in Zn/sup 65/ and total uranium in U/sup 237/ tracers are titrated radiometrically with potassium ferrocyanide or sodium hydroxide and disodium phosphate standard solutions, respectively. A micro amount of zinc is titrated by extracting the dithizonate with carbon tetrachloride. In both cases, the counter used is calibrated with a Zn/sup 65/ or U/sup 237/ standard. This radiometric method has the advantage of simplicity, in that no special indicator and no instruments other than a gamma -ray counter are necessary for determination of the metal ion concentration.
