Caesium-137 - Wikipedia
Caesium-137 (137 55 Cs), cesium-137 (US), [7] or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission of uranium-238. It is ...

Cesium-137: A Deadly Hazard
Along with its intermediate half-life, a combination of high-energy radioactivity and chemical reactivity makes cesium-137 a 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. [4]

Radioactive Cesium 137 - allRadioactive
2022年1月18日 · Caesium 137 is a beta and a gamma emitter. In 94% of the cases, it emits a beta particle (511 keV) turning into a metastable Barium 137m which then emits a gamma-ray (662 keV) before becoming stable. In the remaining 6% of cases, Caesium 137 decays directly into stable Barium 137 by a beta emission (1172 keV).

Once absorbed by a human body, caesium spreads through the muscles until, after the 100 days of its biological lifespan, it disappears. This comparatively quick elimination means that only one nucleus out of 160 will decay inside the human body. In the world of industry, caesium 137 is used for its characteristic penetrative gamma ray signature
