7 concentrates; or alpha emitters with a half-life of less than 10 days. Caesium-137 has a half-life of about 30.17 years. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137m Ba, Ba-137m). The remainder directly populates the ground state of barium-137, which is stable. Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium (barium -137m).

The Half Life For 137 Cesium Is 30 Years. Suppose It Fell 1 Molecule 137. Ce Per Square Meter In The Gavle Area 1986 ( After Chernobyl). 1 Md =6,022x10^23 CESIUM-137 is a radioactive isotope of cesium produced primarily through nuclear faucet which has half-life of 30,23 years. Everything half-life.

Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium (barium -137m). The metastable isotope (barium -137m) is rapidly converted to stable barium-137 (half-life of about 2 minutes) accompanied by gamma ray emission whose energy is 0.662 MeV.
Half-life: 30.17 years. Mode of decay: Beta and gamma radiation. Chemical properties: Liquid at room temperature, but readily bonds with chlorides to form a powder. What is it used for?

Being a radioactive substance, Cesium-137 emits beta and gamma rays. 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 is a gamma emitter with a half-life of 30.08 years.
