HB 01-19-10 Half-Life of Ba-137m 2 radioactive barium will reach an equilibrium amount in 4-5 barium half-lives. When needed for the experiment, the barium is ushed out of the source by an \eluting" solution. Elute is a verb that means to remove an adsorbate from an absorbent by means of a solvent. The
Okt. 2020 Daten und Eigenschaften des Isotops Barium-137m. Electromagnetic character of the competitive γγ/γ-decay fromBa. In: Nature It has a half-life of about 30.17 years, and decays by beta emission to a metastable nuclear isomer of barium-137: barium-137m (137mBa, Ba-137m).
The reader is referred to their paper for the details. A double focusing spectrometer search for positrons gave
The Ba-137m nuclei are a daughter product that results from the λ-decay of Cs-137. 13755 Cs --> 137m56 Ba + e - + νe. As the Cs-137 nuclei decay to the Ba-137m nuclei, the Ba-137m atoms remain adsorbed on the surface of the resin.

Half-life of Barium-137 m.
However, most of the atoms are metastable; this means that their nuclei contains a little extra energy that isn’t released right away. When it is released, it usually comes out in the form of a gamma ray.

Barium-137m is a product of a common fission product – Caesium – 137. The main gamma ray of Barium-137m is 661keV photon. As was written, atomic nuclei
13755 Cs --> 137m56 Ba + e - + νe. As the Cs-137 nuclei decay to the Ba-137m nuclei, the Ba-137m atoms remain adsorbed on the surface of the resin. 2015-09-16 · If we considered only the 137m Ba, once separated from the cesium, the dose would be much lower because the unsupported barium would decay away very quickly.
