8 Apr 2019 Cesium 137 (137Cs, Cs137) is a radioactive isotope of the alkali Cesium 137 undergoes beta (β−) decay and has half-life of about 30 years.

85.1% of all 137 Cs nuclear decays result in 661.7 keV gamma rays). In 5.4% if the cases 137 Cs decays directly into the ground state of 137 Ba by emitting a 1.174 MeV β-particle with no associated gamma. There is no gamma emission because the β-particle carries the entire excess energy released in the process of decay of 137 Cs. External exposure to large amounts of Cs-137 can cause burns, acute radiation sickness and even death. Exposure to such a large amount could come from the mishandling of a strong industrial source of Cs-137, a nuclear detonation or a major nuclear accident.
