Cyclotron production of molybdenum-99 via proton-induced uranium-238 fission
- Univ. of California, Davis, CA (United States)
Technetium-99m ({sup 99m}Tc; 6.02 h) is the most widely used radioisotope in nuclear medicine worldwide. It is currently supplied from elutions of a {sup 99}Mo {r_arrow} {sup 99m}Tc generator and used for regional distribution or locally for institutional use. The parent {sup 99}Mo (66.02 h) radioactivities are being produced commercially in reactors using the {sup 235}U(n, fission){sup 99}Mo (preferred method) or the {sup 98}Mo(n,{gamma}){sup 99}Mo (less desirable) methods. The production of {sup 99}Mo is based on the operation of a small number of nuclear reactors, most of which have reached decommissioning age. Two new reactors to be dedicated to radioisotope production are now being planned in Canada. Accelerator-based methods for producing {sup 99}Mo and/or {sup 99m}Tc would then provide new alternatives to the current reliance on reactor-based technologies.
