上海市松江区地铁站环境辐射累积剂量监测

Monitoring Environmental Cumulative Radiation Dose in Subway Stations in Songjiang District, Shanghai

  • 摘要: 目的 监测上海市松江区地铁站的环境辐射累积剂量,了解X射线行李包安全检查系统对工作人员和公众的辐射风险。

    方法 采用放置热释光探测器检测松江区9 个地铁站X射线行李包安全检查系统周围环境的辐射累积剂量。

    结果 地铁站X射线行李包安全检查系统周围环境不同位置的辐射累积剂量之间(F=1.549,P>0.05)及年估算辐射吸收剂量之间(F=1.548,P>0.05)差异均无统计学意义。

    结论 松江区地铁站安检系统环境辐射累积剂量极低,对安检工作人员和公众的健康影响风险较小,需继续加强辐射防护并减少不必要的X射线照射。

     

    Abstract: Objective To monitor the environmental cumulative radiation dose in the subway stations in Songjiang District of Shanghai, and to understand the radiation risks of X-ray luggage inspection systems to the staff and the public.

    Methods The environmental cumulative radiation dose of X-ray luggage inspection systems in nine Songjiang subway stations were measured with thermoluminescent detector.

    Results No significant differences were found among cumulative radiation absorbed doses (F=1.549,P>0.05) and annual estimated radiation absorbed dose (F=1.548,P>0.05) in accessible areas.

    Conclusion The environmental cumulative radiation dose is very low and poses little health risks to the security staff and the public. It is important to strengthen the radiation protection and reduce unnecessary X-ray irradiation.
