This study intends to reconstruct the 137Cs deposition over the French territory resulting from the Chernobyl accident, 17 years after its occurrence. This reconstruction is based on the caesium fallout versus atmospheric precipitation relationship during the first week of May 1986, already determined for the Eastern France and the modelling of air masses radioactive load decrease toward West. The deposition map is obtained following the methodology used for the European Commission Atlas. Our map is consistent with estimated deposit over neighbouring countries.
