As a well-known, physical carcinogen, ambient X-ray pollution assessment would be of great importance in today's modern world. Accordingly, the present study was done to measure the exposure level of ambient X-ray at inspection gates of two airports in Iran. According to which, the X-ray was measured at different points of the inspection gates including closed and opened Curtain, as well as seating place of operators beside the X-ray inspection systems. The recorded data were then analyzed by "sign" and t-tests.
The total average exposure level of the measured x-ray was 2.68 ± 0.73 μsv.h(-1). The measured x-ray exposure level was 2.07 ± 0.61 (μsv.h(-1)) released from RAPISCAN X-ray inspection system and 3.3 ± 1.34 (μsv.h(-1)) emitted from HEIMANN X-ray inspection system. Comparison of average x-ray doses of the systems in both airports showed that the minimum and maximum exposure levels were recorded at 1(m) far from the devices and at the entrance of the devices, respectively.
The exposure levels at all measurement points were lower than the occupational exposure limit. This reveals the fact that the exposed operators are not probably at risk of adverse health effects.
作为一种众所周知的物理致癌物质,环境 X 射线污染评估在当今现代世界中非常重要。因此,本研究旨在测量伊朗两个机场安检门处的环境 X 射线辐射暴露水平。为此,在安检门的不同位置(包括关闭和打开的幕帘,以及操作人员在 X 射线安检系统旁边的座位)测量了 X 射线。然后通过“符号”和 t 检验对记录的数据进行了分析。
测量的 X 射线总平均暴露水平为 2.68±0.73 μsv.h(-1)。从 RAPISCAN X 射线安检系统释放的测量 X 射线的暴露水平为 2.07±0.61(μsv.h(-1)),从 HEIMANN X 射线安检系统发出的为 3.3±1.34(μsv.h(-1))。比较两个机场系统的平均 X 射线剂量表明,在距离设备 1(m)处和设备入口处分别记录到最小和最大的暴露水平。
所有测量点的暴露水平均低于职业照射限值。这表明暴露的操作人员不太可能面临健康不良影响的风险。
