Abstract:

Superficial X-ray radiotherapy（SXRT） is a radiotherapy technique widely used in the treatment of dermatological conditions， and it is currently primarily employed in clinical settings for superficial skin lesions such as skin cancer，pathological scars，hemangiomas and neurodermatitis. In recent years，its application scope has gradually expanded，and the accompanying radiation risks for patients have also received increasing attention. The clinical application of SXRT and the problems it poses in patient protection are particularly prominent，this is mainly manifested in the fact that a higher proportion of patients receiving SXRT tend to be younger，and the risk of secondary radiation injury is high；Clinically，the protection outside target lesion for patients undergoing SXRT is not properly implemented or even absent；In the actual treatment operation of SXRT，there is a lack of identification rules and individualized protection strategies for SXRT of special population. This article summarizes the establishment of standardized radiation protection measures and operational norms，and points out that on-site measurement of the radiation dose levels and distribution of key tissues outside target lesion of patients undergoing SXRT，as well as the establishment of a SXRT patient protection technical platform，are the practical problems that urgently need to be solved in SXRT patient protection，providing ideas and basis for formulating complete SXRT patient protection norms.
