WebIt decays by emitting a gamma ray, which can be detected by what is effectively a special form of camera. The short half life allows doctors to inject the technetium into a patient in order to light up particular organs in the body and assess how well they work. Generators provide radiation shielding for transport and to minimize the extraction work done at the medical facility. A typical dose rate at 1 metre from 99m Tc generator is 20–50 μSv/h during transport. These generators' output declines with time and must be replaced weekly, since the half-life of 99 Mo is … See more A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope Tc of technetium from a decaying sample of molybdenum-99. Mo has a See more Mo can be obtained by the neutron activation (n,γ reaction) of Mo in a high neutron flux reactor. However, the most frequently used method is through fission of uranium-235 in a nuclear reactor. While most reactors currently engaged in Mo production use … See more When the generator is left unused, Mo decays to Tc, which in turn decays to Tc. The half-life of Tc is far longer than its metastable isomer, … See more Tc remained a scientific curiosity until the 1950s when Powell Richards realized the potential of technetium-99m as a medical radiotracer and promoted its use among the medical … See more Technetium-99m's short half-life of 6 hours makes long-term storage impossible. Transport of Tc from the limited number of production sites to radiopharmacies (for manufacture of specific radiopharmaceuticals) and other end users would be … See more

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.
