Abstract: An online questionnaire was used to investigate the current status of the implementation of five commonly used diagnostic standards for occupational radiation diseases by occupational diagnostic physicians, in order to analyze the implementation effect of the standards and the ability of diagnostic physicians to implement the standards. The results showed that: (1) A total of 87 occupational disease diagnostic physicians were investigated, and the average working years were 15.4±11.9 years; (2) The mastery rate, training rate and application rate of the standard were 82.8%-88.5%, 73.6%-85.1% and 46%-70.1%, respectively; (3) The proportion of diagnostic physicians in standard training departments was 40%-67.1% in health departments, 0.6%-6.4% in environmental protection departments, 8.7%-51.5% in safety supervision departments, and 2.8%-23.6% in our own organization; (4) In diagnostic institutions, the standard system establishment rate was 51.7%-92%, and the standards funds supporting rate was 25.3%-51.7%; (5) The feasible rate of standards determined by diagnosticians was 88.5%-97.7%; (6) Diagnostic physicians’ recommendations on standard revision mainly focused on dose threshold and dose estimation; (7) Diagnostic physicians suggested that the relevant government departments should strengthen the training of occupational disease diagnostic standards and improve the understanding and implementation of the standard technical provisions. This study will provide technical basis for the evaluation and revision of the implementation effect of the five standards.
