Determination of Iodine-131 Specific Activity by Protein lodinationIODINE-131 is obtained either from fission products of uranium-235 or, more conveniently, by neutron irradiation of tellurium in the form of metal or oxide. Naturally occurring tellurium consists of 18.7 per cent tellurium-126, 31.8...
Another sex hormone, progesterone, could also be important for brain functions, as in mammalian species; it acts as a pheromone [113] and promotes male and female sexual behavior [114,115,116]. Theprogesterone receptor(pgr) expression is sex-specific in the ventromedial nucleus of the hypothalam...

Recovery of high specific activity molybdenum-99 from accelerator-induced fission on low-enriched uranium for technetium-99m generatorsA new process was developed to recover high specific activity (no carrier added)Mo from electron-accelerator irradiated UOor uranyl sulfate targets. The process leverages...

The discussion will focus on the chemistry surrounding UREX, MoLLE, and the concentration column in order to achieve high purity, high specific activity99Mo. Potential improvements to this process are also discussed...
