The answer 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.

Cesium 137 beta decay

2009-03-16 · Cesium 137 is a beta negative emitter. In other words, it undergoes a beta-decay. When that happens, one of its neutrons changes to a proton, causing its atomic number to increase by one, and its 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. 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 latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. The time required for a radioactive substance to lose 50 percent of its radioactivity by decay is known as the half-life. Cesium-137 Cesium-137 undergoes beta decay and has a half-life of 30.0 years. How many beta particles are emitted by a 14.0-g sample of cesium-137 in three minutes?
