Radionuclide Basics: Technetium-99 | US EPA
Technetium (chemical symbol Tc) is a silver-gray, radioactive metal . It occurs naturally in very small amounts in the earth's crust, but is primarily man-made. Technetium-99 is produced during nuclear reactor operation, and is a byproduct of nuclear weapons explosions. www.epa.gov

Technetium-99m
Technetium-99m (99mTc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99mTc, that is used in tens of Technetium-99m generators Technetium-99m's short half-life of 6 hours makes storage impossible and would make transport very expensive. wikipedia.org
