  1. Caesium-137 has been used in hydrologic studies analogous to those with tritium. As a daughter product of fission bomb testing from the 1950s through the mid-1980s, caesium-137 was released into the atmosphere, where it was absorbed readily into solution. Known year-to-year variation within that period allows correlation with soil and sediment.
  2. More than twenty years after the Chernobyl accident, attention focuses mainly on one particular radioactive nucleus : caesium-137. Iodine-131, dreadful in the weeks following the disaster, has disappeared because of its 8 days radioactive half-life (or period).On the contrary, because of their periods of thirty years, the effects of cesium-137, and to a lesser degree those of one other.

Caesium-137 (137 55Cs, Cs-137), cesium-137, or radiocaesium, is a radioactive isotope of caesium which is formed as one of the more common fission products by the nuclear fission of uranium-235. Instable isotope of caesium, physical half-life ca. 30.2 years Caesium-137 (also spelled cesium) is a radioactive isotope of caesium which is formed mainly as a fission product by nuclear fission. It has a half-life of 30.07 years, and decays by beta decay to a metastable nuclear isomer of barium-137 (Ba-137m).

  2. Caesium-137 (137 55 Cs, Cs-137) is a radioactive isotope of caesium which is formed as a fission product by nuclear fission.. It has a half-life of about 30.17 years, [3] and decays by beta emission to a metastable nuclear isomer of barium-137: barium-137m (137m Ba, Ba-137m). (About 95 percent of the nuclear decay leads to this isomer. The other 5.0 percent directly populates the ground state.
  3. Cesium-137 decays in the environment by emitting beta particles. As noted above, cesium-137 decays to a short lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. Cesium-137 is significant because of its prevalence
