Half life of technetium
Technetium-99m ("m" indicates that this is a metastable nuclear isomer) is used in radioactive isotope medical tests. For example, Technetium-99m is a radioactive tracer that medical imaging equipment tracks in the human body. It is well suited to the role because it emits readily detectable 140 keV gamma rays, and its half-life is 6.01 hours (meaning that about 94% of it decays to technetium-99 in 24 hours). The chemistry of technetium allows it to be bound to a va… Webtechnetium (Tc), chemical element, synthetic radioactive metal of Group 7 (VIIb) of the periodic table, the first element to be artificially produced. The isotope technetium-97 (4,210,000-year half-life) was discovered (1937) …

Technetium-99m ( Tc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world. Technetium-99m is used as a radioactive tracer and can be detected in the body by medical equipment (gamma cameras). It is well suited to the role, because it emits readily detectable ga…
cooking time for 3.5 kg turkeyWeb97m Tc is the most stable, with a half-life of 91.0 days (0.097 MeV). This is followed by 95m Tc (half-life: 61 days, 0.038 MeV) and 99m Tc (half-life: 6.04 hours, 0.143 MeV). 99m Tc only emits gamma rays, subsequently decaying to 99 Tc. For isotopes lighter than 98 Tc, the primary decay mode is electron capture to isotopes of molybdenum. cooking time for 2 lb roastWebIt mimics calcium and therefore gets trapped in bone. This gives it a long biological half-life to go with its long physical half-life, making it doubly dangerous. Technetium, 99m Tc, is one of the favorites for diagnostic scans because of short physical and biological half-lives.
