An international consortium of scientists, including the Laboratoire des Sciences du Climat et de l'Environnement (LSCE - CEA/CNRS/UVSQ, Institut Pierre Simon Laplace, Université Paris-Saclay), used a new method to refine the map of caesium and plutonium radionuclide concentrations in soils in France and several neighbouring countries. Using a bank of European soil samples, the scientists traced the sources of the deposition of these radionuclides between 1960 and 2009, based on the isotopic signature of their fallout and in particular the caesium/plutonium ratio. This study was published in Scientific Reports on 16th July 2020. This radiological map of Western Europe, which is more precise than the European Atlas available until now1 thanks to the use of multi-parameter spatial models, makes it possible to build up a set of reference data made available to the scientific community on the ESDAC2 site for future studies.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
