Production of medical radionuclide
67
Cu by the irradiation of Zn of natural isotopic composition by bremsstrahlung photons of maximum energy of 55 MeV was studied. Production yields of
67
Cu and other activation products were determined. The yield of
67
Cu is (2.34 ± 0.07) × 10

) at EOB. The experimental data were compared with the results of other experiments and theoretical calculations based on the statistical model in the TALYS software and on the combined model of photonuclear reactions. Technique of chemical separation of
67
Cu from irradiated zinc target based on extraction chromatography using CU Resin was applied. Radiochemical yield was > 95%, separation time was 1 h. The possibility of production of medical quantities was discussed.
