2. Stable and radioactive cesium in the environment. Cesium occurs naturally in soil and water as stable isotope derived from soil minerals. Radioactive radiocesium is generated mainly by three reasons: discharge from reprocessing plants, global fallout after testing of nuclear weapons, and fallout after accidents such as the Chernobyl and the Fukushima nuclear incidents (Ashraf et al., 2014a).
