目的掌握石家庄空港口岸放射性有害因子分布情况及常见放射性元素的参考本底值范围。方法根据石家庄空港口岸具体情况,选择具有代表性的监测点,定期进行放射性监测,并对数据进行统计分析。结果石家庄空港口岸T1航站楼内射线的放射性本底值为0.193μSv/h,靠泊航空器上γ射线的放射性本底值为0.076μSv/h,两者差异有统计学意义(P<0.01)。结论掌握了石家庄空港口岸放射性本底值,为今后口岸入境旅客及行李的核辐射监测工作的开展提供科学依据。
Objective To investigate the distribution of radioactive harmful elements in Shijiazhuang Airport Port and the reference background of common radioactive elements. Methods According to the specific conditions of Shijiazhuang Airport Port, a representative monitoring point was selected, radioactive monitoring was conducted regularly, and the data were statistically analyzed. Results The radioactive background of Shijiazhuang Airport Port T1 terminal was 0.193μSv / h, and the radioactive background of γ-ray on berthing aircraft was 0.076μSv / h. The difference was statistically significant (P0.01) . Conclusions Grasping the radioactive background of Shijiazhuang Airport Port provides a scientific basis for the future nuclear radiation monitoring of passengers and luggage entering the port.
