In order to prevent accidents involving dangerous goods (including radioactive materials), the transport of dangerous goods (TDG) is subject to international regulations incorporated into French law, with a few specific national provisions where applicable. The prevention of transport accidents relies on technical provisions (robustness of packaging, stowage, etc.) and organizational provisions (training of persons in charge of TDG, safety instructions, appointment of a safety advisor in companies loading, unloading, or transporting dangerous goods, etc.) required by regulations.
ASNR participates in the IAEA International Conference on Nuclear Emergency Preparedness and Response (EPR 2025)
