A procedure is given for the determination of Sr/sup 89/ and Sr/sup 90/. The concentration of strontium is made possible by the insolubility of its nitrate salt in strong nitric acid, whioh allows the removal of the greatest pant of the calcium. The punification is performed on a cation exchange column. The amount of Sr/sup 90/ is determined by means of its daughter product Y/sup 90/ necessary calibrations and computations are given. With regard to the reproducibility of the measurements, the fluctuations are less than 20%. This seems satisfactory for a technique having great sensibility and requiring much time and great care.
