The decay scheme of the nuclide is shown in the figure 1 Fig. With a fission yield of 6.2%, it is produced in relatively large quantities in atomic bomb explosions (KATCOFF 1958) and, with a physical half-life of about 30 years, remains in the environment over the long term. *=valid for total cesium (Cs-134 + Cs-137) Radiocesium: Cesium 137 is relevant for radiation biologyįrom a radiobiological point of view, Cs-137 is the most important Cs isotope.
