Following atmospheric nuclear weapons testing in the 1950s and 1960s significant quantities of 137Cs and 239+240Pu were deposited worldwide. In recent decades, 137Cs has been commonly used as a tracer of soil erosion and sedimentation, particularly in the Northern Hemisphere where atomic deposition was three times as great as in the Southern Hemisphere. The relatively short 30-year half-life of this isotope means that its sensitivity as a tracer is rapidly decreasing. In contrast, with...[Show more]
