Abstract. Over the last 5 years France gained a feedback on its NORM industries situation. Regulation imposes to the operators to assess effective doses for workers and members of the public. Theses data were used to update the list of industrial sectors to be regulated for NORM use or storage.

Abstract. The French Decree of 25 May 2005 [4] relative to activities using naturally occurring radioactive materials (NORM) not used because of their radioactive properties imposes that the operators assess effective doses received by workers and populations. To date, about sixty studies have been submitted to the French public authorities. Within this context, the French public authorities asked IRSN to develop a tool for evaluating the quality and the comprehensiveness of these studies and for identifying industrial plants with radiological protection problems. This tool is aimed at helping the regional representatives of French public authorities in their duty to analyse these studies. The aim of this presentation is to illustrate the application of the tool developed by IRSN and to present the French feedback.
