Objective: This study aims to assess the impact of different protective measures on radiation leakage from medical electronic linear accelerators, with the goal of providing a scientific foundation for practical applications. Methods: The experiment was conducted from August 2023 to December 2023. The usage data of medical electronic linear accelerators were randomly divided into a control group and an experimental group, each consisting of 50 cases. The control group received basic protective measures, while the experimental group received enhanced protective measures. We collected data on radiation source leakage, patient exposure dose, equipment reliability score, and operator exposure level score, and utilized the SPSS 26.0 system for data analysis. Results: The experimental results demonstrated that the radiation source leakage, patient exposure dose, equipment reliability score, and operator exposure level score were all significantly improved in the experimental group compared to the control group (P < 0.05). Conclusion: Enhancing protective measures in the utilization of medical electronic linear accelerators can effectively reduce radiation source leakage dose, enhance radiation protection, improve equipment reliability, and lower operator exposure levels. These findings provide a scientific basis for practical applications and contribute to enhancing the safety and reliability of the beam extraction process in medical electronic linear accelerators.
