Surface functionalization to provide flexible surface sources

International audienceDuring the decommissioning and dismantling process, the initial cartography of all the surfaces is vital in classifying potential future waste, depending on their radioactivity level. Contamination monitors, commonly used to measure the surface contamination, need to be calibrated in terms of emitted flux or Bq.cm$^{-2}$ using adequate surface sources. The major drawbacks of existing reference sources is that they are not representative of real sites and their surface areas are limited (
