Caesium is mined mostly from pollucite, while the radioisotopes, especially caesium-137, a fission product, are extracted from waste produced by nuclear reactors. Caesium - Wikipedia The level of contamination with caesium-137 was around 555 kBq/m 2 (surface ground deposition in 1986).

Caesium - Wikipedia The level of contamination with caesium-137 was around 555 kBq/m 2 (surface ground deposition in 1986). Cesium_137's style was much mellower and synthpop inspired and less angst-ridden on these releases than on Advanced/Decay. In 2006, Cesium_137 released their album Intelligent Design. Like its predecessor, it was released by Metropolis.

The diagram reads as follows: the element #55 – cesium (which is a spin 7/2 fermion with positive parity and the atomic weight of 137 amu) is not stable and decays with a half-life of 30.17 years by emitting a beta-particle (β is just another name for a high-energy electron). In these cases, cesium was one of many radionuclides present in the release.

Cesium t.ex. fördelas ganska jämnt i kroppen, i framförallt musklerna, redan några dagar efter ett sönderfallsdata för de använda radionukliderna tagits från Decay Data Evaluation Project Transfer of 137Cs from Chernobyl debris and.
