Abstract: A method for the detn. of the radioisotopes ⁹⁰Sr, ¹⁴⁰Ba, and ²²6Ra in urine and drinking and industrial waters was described. After adding Sr and Ba salts as carriers, the alk. earth elements are pptd. as carbonates. Ca is sepd. by the nitrate method. Sr, Ba, and Ra are sepd. on the ion exchanger Katex S by elution with 4.0% soln. of NH₄ citrate at pH 7.8-8.1.
