摘要
目的了解西北某市地铁一、二号线X射线行李包检查系统放射防护情况并进行安全性分析。方法使用FD-3013H环境监测用X、γ辐射空气比释动能率,按照《X射线行李包检查系统卫生防护标准》(GBZ 127-2002)的要求进行检测。结果 X射线行李包检查系统行李包出口处空气比试动能率均值最高(1.08μGy/h),最高值为2.29μGy/h;其次为检查系统顶部(均值为0.97μGy/h)、行李包入口(均值为0.97μGy/h)、检查设备右侧(均值为0.65μGy/h)、检查设备左侧(均值为0.61μGy/h)、手检工作人员操作位(均值为0.16μGy/h);引导工作人员操作位、值机工作人员操作位基本接近本底辐射水平。结论目前西安市地铁一、二号线X射线行李包检查系统放射防护情况符合《X射线行李包检查系统卫生防护标准》的要求,该系统在正常运行状态下,不会对放射工作人员及公众的健康与安全造成影响。
Objective To understand the radiation protection of the X-ray luggage inspection system in Xi'an metro line one or two,and to analyze the safety of the system.Methods X and gamma radiation air kerma rate using FD-3013H environmental monitoring in accordance with the requirements of Standard for sanitary protection of the X-ray luggage examination system,GBZ 127-2002.Results X ray luggage inspection system at the outlet of the air parcel had the highest average kinetic energy(1.08μGy/h),the highest value was 2.29μGy/h;the inspection system at the top(mean 0.97μGy/h),at the entrance(mean 0.97μGy/h),check on the right side of the device(mean 0.65μGy/h),inspection equipment on the left side(mean 0.61μGy/h),the hand inspection staff operating position(mean 0.16μGy/h);to guide the staff to operate,check in staff operating position close to the level of background radiation.Conclusion At present,the radiation protection of the X ray luggage inspection system of Xi'an metro line 1 and 2 conforms to the requirements of the Standard for sanitary protection of the X-ray luggage examination system.The system is in normal operation.It will not affect the health and safety of radiation workers and the public.
