THE CONTINUING IMPORTANT ROLE OF HIGH FLUX RESEARCH REACTORS FOR PRODUCTION OF THERAPEUTIC RADIOISOTOPES

摘要

indirect route in modest flux reactors. The indirect production of ~(195m)pt - an Auger electron emitter - from ~(193)Ir is only practical at high flux. Thorium-229, the parent of ~(225)Ac for the ~(225)Ac-~(213)Bi generator - can be produced by irradiation of ~(226)Ra. This route is being evaluated as an alternative source to extraction from ~(233)U. In this paper the unique capabilities of very high flux reactors are reviewed for the production of high specific activity therapeutic radioisotopes which cannot be practically produced in lower flux research reactors.
