Probabilistic safety assessment (PSA) techniques are a key tool used in safety assessments. The IAEA has undertaken a Coordinated Research Project on the application of PSA techniques to radiation sources used at medical and industrial facilities. This report presents the studies’ results, including the safety insights and recommendations obtained, the benefits and limitations of PSA techniques, and guidance for performing PSA studies for radiation source applications. In addition, an overview of the techniques and approaches used in each study and the practice specific results are presented. The risk insights obtained constitute potential safety issues to be considered by practitioners, facility staff and management, equipment designers and regulators, in their safety management and risk evaluation activities. Further, it is intended that international organizations will review the information contained in this report and will take account of it in the development of guidance and requirements related to radiation sources.
