What is it used for? Cs-137 is used in small amounts for calibration of radiation-detection equipment, such as Geiger-Mueller counters. Cesium-137 decays in the environment by emitting beta particles. 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 decays to a stable form of barium. Cesium-137 is significant because of its prevalence, particularly dangerous fission product.

+ selectivity; radioactive the annual amount of the radionuclide's consumption (that may be alienated when harvesting) is less than 0.01%, while the rate of Cs-137 radioactive decay is Since this process takes place so rapidly, from a simplified perspective, the decay of cesium-137 is accompanied by both β-radiation and γ-radiation. The main It decays by emission of a beta particle and gamma rays to barium-137m.

What is it used for? Cs-137 is used in small amounts for calibration of radiation-detection equipment, such as Geiger-Mueller counters. This is a supplemental video I am doing for a case presentation regarding the class (Bio statistics & Epidemiology) I am taking over the summer of 2013. 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).

About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137m Ba, Ba-137m). 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. Cesium-137 has an atomic number of 55, so is written as. 137 55 Cs. It is also a β -emitter, which means it undergoes β -decay by a neutron decaying into a proton, releasing an electron.

Cesium 137 undergoes beta (β−) decay and has half-life of about 30 years. Cesium 137 produces gamma emission at 662 KeV and 32 KeV. The screen shown below refers to the isotope Cesium 137 Mode of decay: Beta and gamma radiation. Chemical properties: Liquid at room temperature, but readily bonds with chlorides to form a powder.

It is this decay product that makes cesium an external hazard (that is, a hazard without being taken into the body). Cesium … Cesium-137 β and γ Decay, 30.17 Year Half-life Cesium-137 beta decays into barium-137, normally into an excited state. The Ba-137 emits a gamma ray, and is then stable.
