2018-01-11 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 Cesium-137 undergoes high-energy beta decay, primarily to an excited nuclear isomer of Barium 137, which in turn undergoes gamma decay with a half-life of about 150 seconds. [4] The energies of both the beta decay of cesium-137 and the subsequent gamma decay of the excited barium 137 are 512 keV and 662 keV, respectively.

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. The longest-lived isomer is 133m Ba, which has a half-life of 38.9 hours, though the shorter-lived 137m Ba (half-life 2.55 minutes) arises as the decay product of the common fission product caesium-137. Barium-114 is predicted to undergo cluster decay, emitting a nucleus of stable 12 C to produce 102 Sn. Solution for Enter the balanced nuclear equation for the beta decay ( 0/-1e) of cesium-137 Express your answer as a nuclear equation.
