Abstract： The diagnosis of occupational radiation diseases has always been one of the priorities of China's occupational health work. At present, a series of mandatory standards, corresponding to The Classification and Catalogue of Occupational Diseases, have been developed, as the legal basis for diagnosing occupational radiation diseases. The Standardization Law of the People's Republic of China and the Measures for the Management of Health Standards clearly require establishing an evaluation mechanism on the implementation of mandatory standards. However, there are few systematic studies on the evaluation on the implementation of the diagnostic criteria of occupational radiation diseases. Therefore, it is necessary, based on the status quo of the diagnostic criteria of occupational radiation diseases in China, to study and discuss the evaluation on implementing these standards from evaluation approaches, methods, and contents, and to put forward reasonable suggestions. The current diagnostic criteria of occupational radiation diseases in China are relatively complete. It's feasible to evaluate a single criterion or a group of criteria with similar contents and structures. Establishing appropriate evaluation index systems and selecting appropriate methods for systematic and comprehensive evaluation are suggested. The contents of the evaluation include standard quality, standard implementation, and benefits of standard implementation. Regarding standard quality, more attention should be paid to scientificity, operability, and coordination of relevant standards; regarding standard implementation, the focus is the compliance between actual diagnosis and applied standards; regarding the benefits of standard implementation, social benefits are prioritized.
