The low decay energy, lack of gamma radiation, and long half-life of 135 Cs make this isotope much less hazardous than 137 Cs or 134 Cs. Its precursor 135 Xe has a high fission product yield (e.g. 6.3333% for 235 U and thermal neutrons ) but also has the highest known thermal neutron capture cross section of any nuclide. If the isotope that you wish to decay is not on the drop down list, check the 'not listed' check-box and manually enter the isotope name and its half-life to perform the calculation. You may enter date or time or a combination of both.

The barium-137 is generated in an excited state (what is referred to as “ metastable”), but becomes stable after release of γ-radiation. cesium-137 decay. Cesium- Cesium-137 decay has a half-life of 30.07 years and proceeds by both beta decay and gamma emission from an intermediate state.
