In this paper the analytical procedrure for determination of 21 elements in these samples with Ge (Li) γ-ray spectrometry and group separation were described . After neutron irradiation, the samples were decomposed with a mixture of HF-HNO3-HC1O4, the group separation was achieved by passing the solution through strong basic anion exchange columns. The (51)Cr was sorbed on the co- lump with the solution acidity of 0.5 M HCl, 59Fe and 60Co were sorbed on another column with the solution acidity of 9 M HCl, and 46Sc was sorbed on a reversed-phase chromatographic column with solution acidity of 0.01 M HCI. The results were close to those already published in the literature.
