Cesium-137 is a radioactive isotope with a half-life of 30.2 years. It undergoes β decay to produce barium-137m, an unstable nuclear "isomer" that further decays to the stable barium-137 nucleus by γ emission: 137 55 Cs → 137m 56 Ba + 0 −1e 137m 56 Ba → 137 56 Ba + γ The half-life …

The isotope generator produces the isotope barium-137m from cesium-137. After extraction from the generator this isotope decays by gamma emission with a half life of about 2.6 minutes. The isotope generator can be used up to 1000 times before replacement is required.

Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium (barium -137m). The metastable isotope (barium -137m) is rapidly converted to stable barium-137 (half-life of about 2 minutes) accompanied by gamma ray emission whose energy is 0.662 MeV.

List of Barium Isotopes and Barium Applications: Barium-130 isotope (Ba-130 isotope, 130Ba isotope). BARIUM-130 isotope is used for Barium-131 (Ba-131 isotope, 131Ba isotope) positron-emitting radionuclide (radioisotope) production (can be used in life science for healthcare and medical applications and pharmaceuticals industries);

Both of these are gamma emitters. The instrument you'll use, the Geiger tube, Radioactive half-life. Parent. Caesium-137. 30 years.

In this lab you'll observe the radiation produced by Strontium-90 and Barium- 137m. Both of these are gamma emitters. The instrument you'll use, the Geiger tube,

137m. Ba is only 2.55 minutes. Because of their different chemical behavior, Cs and Ba can be readily separated and the half-life of the short-lived barium isotope can be followed directly.
