Long term decrease of 137Cs bioavailability in French pastures: Results from 25 years of monitoring

Identification of the Origin of Radiocesium Released into the Environment in Areas Remote from Nuclear Accident and Military Test Sites Using The 135cs/137cs Isotopic Signature

“…With more than 1.4x10 8 Bq dispersed into the environment and its relatively long half-life, 137 Cs is considered as the main source of long-term artificial radiation to the public [4][5][6][7][8] . Its monitoring in the environment is therefore of major interest to evaluate the risks incurred by the population and ecosystems [9][10][11][12] . It is therefore essential to be able to identify unambiguously the origin of radioactive contamination and to anticipate their potential impacts.…”
