DOIAbstract
International audienceBetween October 2017 and May 2019, measurements of tritium in rainwater were carried out at several sites innorth-west France. Tritium is an important tracer for hydroclimatic studies and this work provided up-to-datedata that we compared with Global Network for Isotopes in Precipitation (GNIP) measurements. Of thevarious sites studied, some could potentially be affected by atmospheric gaseous emissions from the nuclearindustries in the region (reprocessing plant, nuclear power plant). On our reference site, the activities measuredin rainwater are often below the decision threshold (<0.15 Bq.L- 1). Two other sites with little impact fromnuclear industries have mean activities of less than 0.7 Bq.L- 1. At the two Cherbo...
