Radioactive isotopes of palladium (¹⁰³Pd) and rhenium (¹⁸⁶Re and ¹⁸⁸Re) have found wide use in nuclear medicine. The present report deals with the conditions for their production by a photonuclear method at an electron accelerator. Studies have been made into the channels of target isotope/attendant impurity production as palladium and rhenium targets of natural isotopic composition were exposed to a mixed flux of X-ray (bremsstrahlung) with end-point energy of 40 MeV and photoneutrons. By placing a bremsstrahlung converter and the target inside a neutron moderator, data have been obtained for the effect of photoneutron spectrum on the isotope yield. The simulation technique has been used to investigate the photonuclear yield of target isotopes and major impurities as function of electron energy.
