The Ba-137m atoms are a daughter product that results from the decay of Cs-137 according to the scheme shown in Figure 2. As the Cs-137 atoms decay to the Ba-137m atoms, the Ba-137m atoms remain adsorbed on the surface of the resin, but because barium is in a different chemical form than the cesium was previously, it is more 5 Barium 137 (Barium-137) is a stable (non-radioactive) isotope of Barium. It is both naturally occurring and produced by fission. Barium 137 Carbonate is one of over 250 stable metallic isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications.

To determine the half-life of Barium-137. Materials. isogenerator  Ba - 137m is a generator produced radionuclide where, 137Cs is strongly retained onto a suitable adsorbing material in the form of a chromatographic column  In this experiment, the decay curve of the metastable state Ba−137m of the isotope Ba−137 is recorded and the half-life is determined. Ba−137 is a decay.

3.1 ämne. Formel. Ba (Hill). EG-nr. 137,33 g/mol​. av P Andersson · Citerat av 28 — Den genomsnittliga stråldosen från 137Cs är mycket låg, men är något högre i 137Cs.

As noted above, cesium-137 decays to a short lived decay product, barium-137m . The latter isotope emits gamma radiation of moderate energy, which further. X-rays from 137mBa (2.552 m 1).

Bariumsulfat (BaSO 4) er kvitt eller gulkvitt og vert brukt i måling. Sjølv om barium er svært giftig, vert bariumsulfat òg brukt til røntgenundersøkingar av mage og tarm. Det er fordi bariumsulfat er uløyseleg i vatn og ikkje blir tatt opp i kroppen.
