137m, the metastable state that is a product of Cs -137 radioactive decay. The half-life is the amount of time it takes N radioactive nuclei to decay to half of the original radioactive nuclei. The isotope generators that we are using contain up to 10 μCi (370 kBq) of Cs-137 (± 20%) bound on a special ion exchange medium and can produce the
Half-life: 30.17 years. Mode of decay: Beta and gamma radiation. Chemical properties: Liquid at room temperature, but readily bonds with chlorides to form a

You will be given a geiger counter and a sample which contains a small number of barium (Ba) ions (more specifically, the isotope 137Ba) that have been created passes into the ground state of Ba−137 via γ decay with a half-life of only 2.551 min. The student will measure the half-life of metastable Barium-137.
2009-03-16 · Cesium 137 is a beta negative emitter. In other words, it undergoes a beta-decay. When that happens, one of its neutrons changes to a proton, causing its atomic number to increase by one, and its atomic mass to remain the same. Atomic number of cesium is 55, so the new atomic number 56 belongs to barium.
During the indirect decay, beta rays having a maximum energy of 0.513 MeV are released. 1 Decay Scheme 133 Ba disintegrates by electron capture mainly to two 133 Cs excited levels of 437 keV (85.4%) and of 383 keV (14.5%) with three very minor branches to the 160 keV, 81 keV excited levels and the ground state.

Its decay results in the formation of Ba-137 with a very short half-life. Both elements have the same atomic mass but cesium has an atomic number of 55 and barium has an atomic number of 56. Because they are different elements, they have different chemical properties and can be separated by chemical processes. 137 decays to a short-lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium.
Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions.
