1 2002-01-01 Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium that 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. Cs-137 is used in small amounts for calibration of radiation-detection equipment, such as Geiger-Mueller counters.

A watershed-scale 137 Cs transport model was developed and applied to a forested catchment in Fukushima area. This model considers 137 Cs wash-off from vegetation, movement through soils, and transport of dissolved and particulate 137 Cs adsorbed to clay, silt and sand. 2016-08-22 damage. Cs-137 is used in medical therapy for oncology, industrial radiography, radiation gauges, food irradiators, and soil testing.
