Excerpt: Technetium-99m is a metastable nuclear isomer of technetium-99, symbolized as Tc. The "m" indicates that this is a metastable nuclear isomer, i.e, that its half life is considerably longer (by several orders of magnitude, at least) than most nuclear isomers which undergo gamma decay. As in all gamma decay reactions, a metastable nuclear isomer does not change into another element (transmute) upon its isomeric transition or "decay". The life-time of technetium-99m is very long in terms of average gamma-decay half-lives, though short in comparison with half-lives for other kinds of radioactive decay, and in comparison with radionuclides used in many kinds of nuclear medicine tests. Techetium-99m is used as a radioactive tracer that medical equipment can detect in the body. It is well suited to the role because it emits readily detectable 140 keV gamma rays (these are about the same wavelength emitted by conventional X-ray diagnostic equipment), and its half-life for gamma emission is 6.0058 hours (meaning that 93.7% of it decays to Tc in 24 hours). The "short" half life of the isotope (in terms of human-activity and metabolism) allows for scanning procedures which collect data rapidly, but keep total patient radi.
