Production of 47Sc, 67Cu, 68Ga, 105Rh, 177Lu, and 188Re using electron linear accelerator

Radioisotopes used in nuclear medicine (47Sc, 67Cu, 68Ga, 105Rh, 177Lu, and 188Re) were produced by an electron linear accelerator in this study. Neutron irradiation was investigated as an alternative method for producing 105Rh and 177Lu, and the results were compared with those obtained with the electron linear accelerator. All the radioisotopes except for 177Lu were produced efficiently by the electron linear accelerator. Electron linear accelerators were thus demonstrated to show the desired performance for the on-demand production of medical radioisotopes at consuming places such as hospitals.
