Web1 jun. 2005 · The generator contains 99 Mo (separated from fission products) adsorbed onto alumina contained in a lead-shielded glass column. The internal generator components are contained within a robust galvanized iron casing fitted with a carrying handle. It is a 2-vial system. Web99 Mo decays to 99g Tc (12.4%) and 99m Tc (87.6%), and the latter, with a physical of 6.0067 h, decays to 99g Tc ( = 211,100 years). Due to this particular branching decay of 99 Mo, even fresh elutions from a generator always contain both isotopes ( 99m Tc and 99g Tc), indistinguishable from the chemical point of view.

Web24 okt. 2024 · But its “parent,” the element molybdenum-99 (Mo-99), which decays to produce Tc-99m, has a half life of 66 hours. That means the relatively stable Mo-99 can be transported to hospitals over longer distances to generate Tc-99m on location at the hospital as it decays. enlarge WebA stopper for use in an injector device, the stopper having an outer side configured for engagement with an interior bore of an injector device barrel, includes an elastomer body and a barrier coupled to the elastomer body, the barrier having an inner surface oriented toward the elastomer body and an outer surface oriented away from the elastomer body, … Web2.2.
