How does a technetium generator work
WebTechnetium-99m is produced by bombarding Molybdenum (98Mo) with neutrons. Molybdenum-99 is then produced. This then undergoes a Beta decay with a half life of 66 … WebTechnetium-99m was discovered as a product of cyclotron bombardment of molybdenum. This procedure produced molybdenum-99, a radionuclide with a longer half-life (2.75 days), which decays to 99m Tc. This longer decay time allows for 99 Mo to be shipped to medical facilities, where 99m Tc is extracted from the sample as it is produced.
