Cesium-137 is significant because of its prevalence, relatively long half life (30 years), and its potential effects on human health. Cesium-137 emits beta particles as it decays to the barium isotope, Ba-137m (half life = 2.6 minutes). How are people exposed to cesium-137? People may be exposed externally to gamma radiation Watch the next lesson: https://www.khanacademy.org/math/algebra2/exponential_and_logarithmic_func/exponential-modeling/v/modeling-ticket-fines-with-exponenti Main article: Caesium-137 Caesium-137, with a half-life of 30.17 years, is one of the two principal medium-lived fission products, along with 90 Sr, which are responsible for most of the radioactivity of spent nuclear fuel after several years of cooling, up to several hundred years after use. 2009-03-16 CTRAN Example File: Cesium 137 Transport in an Unconfined Aquifer (pdf)(gsz) Page 7 of 9 Figure 10 Concentration verses time at a coordinate of (95 m, 10 m) The effect of adsorption and decay is manifest in two ways: 1) the arrival time of the peak concentration is delayed; and, 2) the value of the peak concentration is diminished.

Cesium 137 decay

Once released into the environment, caesium-137 is subject to radioactive decay with the emission of beta particles and gamma radiation. Because of the chemical nature of caesium, it move easily throughout the environment, thus making caesium-137 difficult to cleanup. Table of Isotopes decay data.

Bariums halveringstid - Rapport i Fysik - Studienet.dk 137 Cs gamma spectrum. The characteristic 662 keV peak does not originate directly from 137 Cs, but from the decay of 137m Ba to its stable state. Caesium-137 has a half-life of about 30.17 years. 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).
