In recent years, because no atmospheric nuclear bomb tests have been conducted, leakage accidents at nuclear power plants have become the major concern.

  • Caesium-137 Wikipedia

    Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium which is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.Trace quantities also originate from natural fission of uranium-238.It is among the most problematic of the short-to-medium-lifetime fission products

    There is much concern about radioactive contamination in both the watershed of the Abukuma River, which flows through Fukushima Prefecture, and its estuary, where it discharges into the sea in Miyagi Prefecture. We investigated radioactive cesium dynamics using mixing diagrams obtained from hydrographic observations of the Abukuma River Estuary. Particulate radioactive cesium dominates

    WHY CESIUM-137? Properties of radioactive 137CS make it unique as a tracer for studying erosion and sedimentation. There are no natural sources of 137CS. Cesium-137 is pro-duced during nuclear fission. Thus, its presence in the environment is due to nuclear testing or to releases from nuclear reactors (Wise, 1980; Walling et al., 1986b).
