Cs-137 has a nuclear spin of 7/2. It can decay into 3 different Ba-137 levels, the ground state, and two excited states. The majority go through an excited state with spin 11/2. The other two states have spin 1/2 or 3/2 (the ground state). So, a few more states to decay to, but some pretty large spin mismatches on several of them.

particularly dangerous fission product. 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. The energies of both the beta decay of cesium-137 and the subsequent

Cesium-137, a beta emitter… The suggestion to use caesium-137 (137Cs) as a tracer for soil erosion represents the initial 137Cs fallout input (only reduced by radioactive decay). These. Cesium-137 (Cs-137) is a radioisotope and unstable a lesser extent, high- energy beta particles, which disrupt natural processes, or when it decays. When a Fig. 1. Schematic representation of the beta minus decay of Cs-137.

It is produced in some abundance by fission reactions. 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.

Beta decay of Cs-137 – and other nuclei Fig. 3 below gives a quite detailed view of the decay. Further details on the decay will be mentioned below. Fig. 3: decay scheme for Cs-137 As shown in fig. 3 94,7% of beta-minus decays ends in the exited state h 11/2-, and 5,3% goes to the ground state d 3/2+ of the Ba-137 nucleus.

order polynomial was found to be the best fit to the experimental data. For emergency assistance, call 911 For EH&S emergencies, including after hours, call (650) 725-9999 A beta decay often comes with the emission of a gamma-ray due to the desexcitation of the nucleus.

Cesium-137 decay has a half-life of 30.07 years and proceeds by both beta decay and gamma emission from an intermediate state. Both the electron and gamma emissions are highly ionizing radiation. The gamma radiation is very penetrating, and the beta radiation, though very short range, is very dangerous when ingested because it deposits all that

Cesium (Cs) 137 Radioactive Isotope Decay Calculator Online radioactive decay calculator that allows you to find out the radioactivity decay in Cesium (Cs) 137. Note: The calculation of radioactivity in minerals is based on certain assumptions. Recommended Nuclear Decay Data Cs-137. Decay Mode: β ¯ Half-Life: (11000 ± 90) d Cesium-137 decay has a half-life of 30.07 years and proceeds by both beta decay and gamma emission from an intermediate state. Both the electron and gamma emissions are highly ionizing radiation . The gamma radiation is very penetrating, and the beta radiation, though very short range, is very dangerous when ingested because it deposits all that energy in a very short distance in tissue. Caesium-134 is not produced via beta decay of other fission product nuclides of mass 134 since beta decay stops at stable 134 Xe. It is also not produced by nuclear weapons because 133 Cs is created by beta decay of original fission products only long after the nuclear explosion is over.

Sal constructs a function to model the decay of a radioactive element. Throughout this video, the half-life of Cesium 137 is mistakenly taken to be 30 days, 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.
