The data file for this experiment is on your computer. This data is for the isotope. 137. Ba*, which has a half-life The isotope generator Barium 137m contains Cesium-137 as the long parent nuclide, which has a half-life of 30.25 years. Cs137 decays, by emission of beta 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. The parent isotope Cs-137 with a half-life of 30.1 years beta decays (94.6%) to the metastable state of Ba-137m.
When a kernel pops This is data run number two in our experiment to measure the half-life of barium-137m. Choose your detector and start collecting data!

Radioactive decay and the half-life concept can be shown by three methods, each of Radon-220 from thoriated gas mantles; (2) by the elution of Barium- 137m 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, Radioactive half-life. Parent. Caesium-137.

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 …
lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. Cesium-137 is significant because of its prevalence, relatively long half life (30 years), and its potential effects on human health.

137m is 2.55 min and is the half-life that is the subject of this lab. The cesium is bound The cesium is bound on an ion exchange medium and hopefully stays in the source. Steve: The half-life of metastable barium-137 is listed as being 2.552 minutes, which is about 153 seconds.
