How is molybdenum 99 produced
WebMolybdenum-99 is the parent isotope of technetium-99m (Tc-99m), a short-lived, gamma-emitting isotope used in about 85% of all nuclear medicine diagnostic scans. The vast majority of the world’s supply comes from several aging nuclear reactors, none of which … Web99m Tc, which is widely employed as an imaging agent in nuclear medicine, is another useful red cell label. This metastable radionuclide is produced in a molybdenum generator as a product of molybdenum-99 decay. 99m Tc decays, in turn, to 99 Tc, with a half-life of 6.02 hours. In doing so, 99m Tc emits a gamma-photon at 140 keV, which falls ...
