Electron accelerator's production of technetium-99m for nuclear medicine

At present Technetium-99m provides up to 90% isotopic products used in nuclear medicine. The generator Molybdenum-99 is mainly produced in fission reactors. Most of reactors used for this production are approaching the end of their working life. One suggests to use photonuclear reactions in /sup 100/Mo under influence of bremsstrahlung of a powerful electron accelerator as an alternative method of /sup 99m/Tc production. Report contents both an analysis, of some technical, economical and ecological aspects of method and the results of experimental production of /sup 99m/Tc with KIPT electron linac, as well as results of medical test of produced radiopharmaceuticals.
