Abstract: Risk identification of radiation sources is related to its inherent characteristics, radiation protection facilities and operating conditions, as well as implementation of laws and regulations. Based on the practice of radiation safety supervision, and technical procedures of daily supervision and inspection, factors that have important influence on radiation safety were generalized, summarized and refined. Combined with widely solicited peer opinions and suggestions, an evaluation index system of radiation risksources was established. The Analytic hierarchy process (AHP) based on Expert Supporting Degree was used to provide the weight of each risk evaluation index, todetermine the risk level of a radiation source unit. The study will provide thetheoretical basis for classification management of radiation risk sources, realize the dynamic classification management of radiation sources, and improve theefficiency of radiation regulation.
