Technetium-99m generator Wikipedia

A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope 99m Tc of technetium from a decaying sample of molybdenum-99. 99 Mo has a half-life of 66 hours and can be easily transported over long distances to hospitals where its decay product technetium-99m (with a half-life of only 6 hours,

Production of Technetium-99m Radioactive Isotopes

Molybdenum-99 is then produced. This then undergoes a Beta decay with a half life of 66 hours to produce Technetium. The production of Technetium-99m is then able to be permitted for medical purposes. Like all isotopes of Technetium, Technetium-99 isn't stable and finally ends up, following another Beta decay, as Ruthenium-99.

Technetium-99m Wikipedia

Technetium-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 Tc-99m. At present, molybdenum-99 (Mo-99) is used commercially as the easily transportable source of medically used Tc-99m.

Technetium-99m generators | MrReid

Hospitals cannot run their own nuclear reactors and so they rely on technetium generators – machines that produce Tc-99m from the decay of its parent isotope molybdenum-99. Molybdenum-99 has a longer half-life (66 hours) and can therefore be transported to hospitals and still remain useful for up to a week.
