摘要
Abstract
Objective To explore the radiation dose the public received while the mobile bedside X-ray machine is working. Methods Firstly, the radiation dose of hospital's centralized ward was detected. Based on the detected radiation dose rate, a mathematical model was built to transform it to the annual effective dose according to the clinical regularities. Then radiation protection assessment was made by comparing it with the radiation safety limit specified by the state. Results The annual radiation dose public received was far below than that of annual effective dose limit specified by the state when bedside X-ray machine was working, which met the national safety standards. Conclusion Though the public radiation dose of bedside X-ray machine is within the safety range, it is still necessary to implement protective measures in pediatric intensive care unit, neonatology department and patients' family members who stay beside patient.关键词
