| Abstract: | A neutron-activation analysis method for the determination of traces of cobalt in samples of purified platinum is described. Using a pile flux of 1.2 × 1012 thermal neutrons. cm−2. sec−1, as little as 10−9 g of cobalt may be determined. A rapid radiochemical separation procedure coupled with gamma-ray spectrometry permits measurement of 5.26-year cobalt-60 activity. Results of analysis of seven samples of platinum are quoted. |
