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...
