description: This paper describes an approach to the production of 64Cu radionuclide on a MGC-20 cyclotron when irradiated with a natNI beam of accelerated protons by the natNi(p,n)64Cu reaction. The conditions of exposure were dictated from the theoretical and practical data obtained, as well as by the rules of radiation safety. The kinetic energy of the protons was 10.5 MeV, and the beam current was 3.7 ÂµA. As a result of theoretical calculations, the dependences of the copper-64 isotope operating efficiency on the target thickness and the beam exposure were obtained. Experiments were carried out on the studied technologies for the isolation of 64Cu from a radioactive target, the determination of impurities using a DSpec-50 gammaâray spectrometer on a GEM-FX5825 semiconductor detector, and their purification. After the purification stage, the activity of 64Cu was 0.31 of the 3.25 Â± 0.81 MBq expected. This means that it was not possible to completely separate 64Cu from the column and it is necessary to refine this part of the technology. The purification efficiency from the 55Co impurity was 88.8%. In addition to 64Cu, radi-onuclides 55Co, 57Co, and 58Co were found, formed due to iron impurities in the natNi. The activities of the 57Co and 58Co isotopes are extremely small and it was not possible to make a quantitative assessment of their concentrations in our conditions.
