摘　　要：目的检测某机场X射线行李包检查系统辐射,并进行辐射安全性评价和放射性豁免分析。方法使用451PX巡测仪对X射线行李包检查系统按国家标准规范进行检测。结果71台不同型号的X射线行李包检查系统空气比释动能率均以行李包出口侧(0·38μGy/h)、入口侧(0·33μGy/h)为高,最高值达到1·92μGy/h,其次为工作人员操作位(0·15μGy/h),其余各点基本接近本底。估算每位工作人员年辐射剂量最大值约为0·43mSv/a。X射线行李包检查所增加的集体有效剂量约为0·003人·Sv/a。结论正常工作状态下,使用机场X射线行李包检查系统不会对安检工作人员和旅客产生辐射危害,但不能对其予以放射性豁免。Objective To monitor the dose of the radiation monitoring, to assess the safety the radioactivity exemptions of the X - ray luggage inspection system at an airport. Methods and analyze 451P monitor was used to test the dose of the X - ray luggage inspection system in terms of criterion of the national radiological protection standard. Results The air kerma rate of the 71 sets of different X- ray luggage inspection systems were high at exit （0.38μGy/h） and entrance （0.33μGy/h）, the highest value reached to 1.92μGy/h; 0.15μGy/h was found at the work position, the level of the rest was close to the background. The estimated highest annual dose that the workers receives was about 0.43 mSv/a. The collective effective dose increased by X - ray luggage inspection systems was about 0.003 man· Sv/a. Conclusion In normal working condition, X - ray luggage inspection system would not hurt the workers and passengers, but the radialization could not be exempted
