Caesium - Wikipedia

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 ...

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 has a half-life of 30 years; for example, if 1000 cesium-137 atoms are present, then 500 of these will be transformed into barium-137 over a 30-year period.
