ASN Report 2022

In 2022, the ASN regional divisions, along with the public authorities (Dreal(*), ARS, Dreets(**)) and the partner organisations (Cerema, trade associations, local authorities, etc.), continued the actions to raise the awareness of elected officials, building trade professionals, employers, managers of PAB and the general public to the regulatory changes made since 2018 (see point 3.2.2). This awareness-raising is accompanied by inspection actions. For the PAB, these inspections target the major property managers in particular. ASN ACTIONS TO PREVENT THE RADON RISK IN THE REGIONS AWARENESS-RAISING ACTIONS AUVERGNE‑RHÔNE‑ALPES Lyon Division ∙ Participation in a campaign to inform the companies of the region about the radon risk, conducted as part of the Regional Occupational Health Plan No. 4 (PRST4). ∙ Participation in a campaign to inform day-care facilities for young children about the radon risk, conducted under the Regional Health Environment Plan (PRSE), in partnership with the ARS and the Dreal. BOURGOGNE‑FRANCHE‑COMTÉ Lyon Division ∙ Creation of a regional health/environment network to lead the players involved in management of the radon risk and air quality inside buildings. It is based on the digital platform stemming from the Jurad-Bat project and will contribute to its development. BRETAGNE / PAYS DE LA LOIRE Nantes Division ∙ Between 65% and 93% of the municipalities in the départements (Sarthe excluded) of these regions are situated in zones with significant radon potential. ∙ Co-financing in Pays de la Loire of six new awareness-raising actions targeting private individuals and assistance in conducting voluntary campaigns to measure radon in their home and participation in the kick-off meetings of some of these campaigns. ∙ Contribution to an assessment of the campaigns carried out between 2015 and 2021: nearly 4,000 households in the Loire département have thus been able to measure the radon concentration in their home; the concentration is below the regulatory reference level in 84% of them. ∙ Contribution to the actions concerning the evaluation of PRSE3 and the launching of PRSE4. CENTRE-VAL DE LOIRE Orléans Division ∙ Participation in an awareness-raising operation with the ARS (Indre département delegation) and CAP Tronçais with supply of radon screening kits to the persons interested. NORMANDIE Caen Division ∙ Participation in the preparatory work for PRST4 with the Dreets and the ARS. NOUVELLE-AQUITAINE / OCCITANIE Bordeaux Division ∙ Participation in the creation of the “radon” action sheet of PRST4 for Nouvelle-Aquitaine and setting up communication actions targeting the region’s employers and Occupational Safety and Health (OHS) organisations ∙ Participation in the meetings to prepare the future PRSEs. OVERSIGHT ACTIONS AUVERGNE‑RHÔNE‑ALPES Lyon Division ∙ Performance of two inspections of the local authorities (Departmental Councils of the Haute-Savoie and Cantal départements) responsible for educational institutions, two inspections of spas (Royat and Châteauneuf-les-Bains) and one inspection of the underground structure of the EDF hydroelectric power station of Les Bois in Chamonix, a designated radon-risk workplace. ∙ The situation of the Cantal département is to be flagged in particular, as the inspectors have found establishments that have not been monitored since 2016 and still require remedial measures. In particular, the presence of radon at concentrations above the reference level for the last 10 years in two lower secondary schools necessitates an expert assessment of the buildings concerned without delay. ∙ With regard to the spas of Royat, ASN’s inspection was conducted jointly with the labour inspectorate services. The constant presence of radon for more than 10 years necessitates an expert assessment of the buildings concerned without delay. ∙ For the hydroelectric power station of Les Bois, the inspectors noted good management of the radon risk. Radon measurement campaigns have led the employer to consider the entire designated radon-risk workplace as a “radon zone”. The employer has also performed individual dosimetric assessments of the workers and provided passive radon dosimeters for the workers concerned. ∙ The inspectors have observed rigorous management of the radon risk by the Departmental Council of the Aveyron département. A number of situations in the Cantal département require expert assessments of buildings to be carried out without delay. 116 ASN Report on the state of nuclear safety and radiation protection in France in 2022 01 • 01 • Nuclear activities: ionising radiation and health and environmental risks
