Abstract: | An activation analysis method has been developed for the determination of chromium and zinc in biological material. After the samples had been activated in a thermal flux of 7·1011 n·cm−2·sec−1 for 100 hours, both elements were separated from interfering radionuclides by means of ion-exchange and distillation processes. Gamma spectrometry was used to measure the activities of51Cr and65Zn. The practical limits of detection were found to be 1·10−8 g for chromium and 1·10−7 g for zinc. The results of model experiments and of the analysis of blood taken from two individuals proved to be accurate and reproducible. |
