Technetium

The first artificially produced element and a radioactive fission product of URANIUM. Technetium has the atomic symbol Tc, and atomic number 43. All technetium isotopes are radioactive. Technetium 99m (m=metastable) which is the decay product of Molybdenum 99, has a half-life of about 6 hours and is used diagnostically as a radioactive imaging agent. Technetium 99 which is a decay product of technetium 99m, has a half-life of 210,000 years.
