某机场X射线行李包检查系统的辐射防护情况

Radiation prevention of X-ray baggage inspection system in airport

目的掌握地窝堡国际机场X射线行李包检查系统基本情况、辐射防护及辐射剂量照射状况。方法采用X、γ辐射剂量率仪对该机场44台X射线行李包检查系统的辐射剂量进行检测,按照国家放射卫生标准,对各种型号的X射线行李包检查系统放射防护状况及周邻辐射剂量进行分析。结果 44台X射线行李包检查系统各测点的最大测定值均小于5μGy/h,各种机型的X射线行李包检查系统防护性能基本相似,各设备外表及周邻环境的电离辐射水平的差异较小。结论地窝堡国际机场各种机型的X射线行李包检查系统辐射剂量和卫生防护均符合国家放射卫生标准要求;该次监测可为地窝国际机场今后进一步开展辐射防护工作提供可靠的科学依据。

[Objective]To master basic conditions of the X-ray baggage inspection system,radiation prevention and radiation dose exposure at Diwopu international airport.[Methods]Radiation dose of 44 X-ray baggage inspection systems were detected by using X,γ-ray radiation inspection instruments,radiation prevention conditions and neighboring radiation dose were analyzed on various types of X-ray baggage inspection system according to national radiation sanitation standard.[Results]The maximum values were all less than 5μGy/ h for 44 X-ray baggage inspection systems and the protection capacity of various X-ray baggage inspection systems were basically similar.The difference was weak in ionizing radiation level of instrument surface and circumjacent environment among 44 instruments.[Conclusion]Prevention capacity of X-ray baggage inspection systems are basically similar at Diwopu international airport and its radiation dosage accorded with national radiation sanitation standard.This monitoring provide reliable scientific references for further implementation of radiation protection at Diwopu Airport in the future.
