nuclear isomer of barium: barium-137m (137mBa, Ba-137m). The remainder directly populates the ground state of 137Ba, which is stable. Barium-137m has a half-life...

reactivity, barium is never found in nature as a free element. The most common minerals of barium are barite (barium sulfate, BaSO4) and witherite (barium carbonate...

Caesium-137 is one such radionuclide. It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137...

power plant. 137Cs beta decays to barium-137m (a short-lived nuclear isomer) then to nonradioactive barium-137. Caesium-137 does not emit gamma radiation...
