【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,P0.05)及年估算辐射吸收剂量之间(F=1.548,P0.05)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 cumulative dose of environmental radiation in the subway station of Songjiang District, Shanghai, and to understand the radiation risk to the workers and the public caused by the X ray luggage safety inspection system. [Methods the radiation accumulative dose of X-ray luggage safety inspection system in 9 subway stations in Songjiang district was detected by placing thermoluminescence detector. [Results] the accumulative dose of radiation in the environment of the safety inspection system of X-ray luggage in subway station was between F1. 549 and 1. 549. There was no significant difference between P0.05) and the annual estimated radiation absorbed dose (P0.05). [Conclusion] the accumulated dose of environmental radiation in Songjiang metro station is very low and the risk to the health of safety workers and the public is small. It is necessary to continue to strengthen the radiation protection and to reduce the unnecessary X-ray exposure.
