Abstract: According to WS/T 536—2017, “Health Standards Tracking and Evaluation Work Guide.”, 337 radiation health supervisors in 7 provinces of China were polled via questionnaires, regarding their knowledge, comprehension, and application of the current diagnostic criteria for 5 prevalent radiological diseases. Only 47.5 percent (160) of radiation health supervisors are familiar with all five diagnostic criteria for radiological diseases, and 18.4 percent (62) of them are only familiar with one of the criteria, indicating the need for improvement in knowledge, familiarity, understanding, and application of these criteria by radiation health supervisors. The standard “Diagnosis of Acute Radiation Diseases from Occupational External Exposure” has been trained or disseminated to 60% of the health supervisors, whereas the standard “Diagnosis of Occupational Radiation Cataract” has been disseminated only to 4% of the health supervisors. When completing health monitoring duties, about 60% of the respondents used the conventional diagnostic criteria, but citations typically occurred once a year. More than 92% of the supervisors who responded to the survey thought that the diagnostic criteria are in line with the requirements of the prevailing national laws, rules, and standards for occupational disease prevention and treatment. For each criterion, less than 20% of respondents said it wasn’t feasible. More than 50% of supervisory institutions lacks specialized management support funds for occupational disease diagnosis requirements. Only 198 (58.75%) of the respondents’ institutions engaged in specific supervision of diagnostic institutions’ quality management. Less than 20% of respondents to the subjective question survey gave their opinion on the survey. We should increase training and dissemination of diagnostic criteria for radiation health supervisory staff in order to enhance their capacity to implement the standards. Health supervision agencies should increase funding to strengthen special supervision of radiological diagnostic institutions and establish an effective feedback mechanism.
