%X Scandium-47 can be produced indirectly via the 46Ca(n,γ)47Ca→47Sc nuclear reaction by neutron irradiation of calcium targets, either natural or, preferably, enriched in calcium-46. Two target materials differing in the enrichment in calcium-46 and the elemental and isotopic composition were irradiated in the MARIA research reactor. Radioactive concentration of scandium-47 and the radionuclidic purity of the solution obtained after irradiated target dissolution were assessed by gamma-spectrometry using a high-purity germanium (HPGe) detector in the Laboratory of Radioactivity Standards in the Radioisotope Centre POLATOM, NCBJ. The radioactive concentration of scandium-47 was in the range of 0.20–1.48 GBq/mL, and the content of calcium-47 was determined at the level ranging from 0.006 % to 0.055 % of scandium-47 in the final products. The profile of radionuclide impurities and their minimum detectable activities are discussed.
