How is Technetium-99m being produced in hospitals?

Technetium-99m is produced by bombarding Molybdenum (98Mo) with neutrons. ... The production of Technetium-99m is then able to be permitted for medical purposes. Like all ... Technetium generators, which contain the radioisotope, are supplied to hospitals from the nuclear reactor where the isotopes are made. read more

Tc-99m is produced from a generator that contains molybdenum-99. The source of the Mo-99 is a nuclear reactor. Once the Mo-99 is produced, it’s purified and placed into a device that’s referred to as a generator, though it’s actually the Mo-99 that produces the Tc-99m. It does this because Mo-99 is radioactive and decays to Tc-99m. read more

The ‘m’ in the name of technetium-99m indicates that it is metastable. Tc-99m is radioactive because one or more of the protons and neutrons in its nucleus is in an excited state. Tc-99m decays into Tc-99 with a half-life of six hours and this makes it particularly well suited to use in the body: after one day (four half-lives) only 6.3% of the initial Tc-99m remains. read more

Technetium-99m is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope. read more
