Caesium137 has been used in hydrologic studies analogous to those with tritium. As a daughter product of fission bomb testing from the 1950s through the mid1980s, caesium137 was released into the atmosphere, where it was absorbed readily into solution. Known yeartoyear variation within that period allows correlation with soil and sediment ......
