Abstract: In this work, innovatory production of three radioisotopes 117mSn, 186Re and 188Re, which can be used in nuclear medicine, is described. The natural tin and rhenium targets were irradiated by a high-energy 20 MV X-ray therapeutic beam from a medical linear accelerator. Additionally, the targets were in the photoneutron field. The radioisotopes were obtained in photonuclear and neutron reactions. A special lead-PMMA system was used to increase the slowed-down neutron flux in the target volume. The specific activities of 117mSn, 186Re and 188Re are 11 kBq/g, 2.6 MBq/g and 0.26 MBq/g in the saturation state, respectively. The produced amounts of the radioisotopes of tin and rhenium are sufficient for various laboratory tests in nuclear medicine.
