	One well known and very useful nuclear isomer is [[technetium]]-99m. Tc-99m is the most used [[medical isotope]] for diagnostic procedures in the modern world. Tc-99m has a [[half life]] of 6 hours, while Tc-99 has a half life of 210,000 years. Both of these isomers have 43 protons and 56 neutrons, but Tc-99m doesn't last for nearly as long, and undergoes a <math>\~~betha~~^-</math> decay.
