Abstract: In the form of questionnaire survey, 6 cases of occupational acute radiation skin injury diagnosed from 2016 to 2019 were collected and statistically analyzed in terms of length of service, type of work, exposure time, exposure dose and clinical manifestations, and the characteristics of occupational exposure, occupational exposure control points and follow-up feedback of applicable diagnostic criteria were analyzed and discussed. The results suggest that industrial radiation and industrial flaw detection are the key jobs leading to occupational acute radiation skin injury. Radiation units should strengthen the training of radiation workers, especially the pre-job training, to improve the awareness of protection. Workers entering radiation workplaces should not only wear conventional dosimeters, but also carry alarm dosimeters. The diagnosis of occupational acute radiation skin injury involves the diagnostic physician's familiarity with the cviteria, but the key to the diagnosis of occupational acute radiation skin injury is to determine the dose and clinical manifestations.
