海南某机场X射线行李包检查系统辐射水平及剂量分析

摘要

Purpose The main task of this paper is to research and analyze the basic situation of a certain airport X-ray luggage inspection system and the radiation dose levels. Method After in-depth analysis, selected by far the most effective detection methods, namely, radiation dose survey meter method, this method detection level in accordance with the《X-ray luggage inspection system for health protection standard》[2]“.Result through the detection for all types of the airport X-ray luggage inspection system, its protective properties is approximately the same, all the testing point of maximum measurement is less than 386.5, which is less than the required level of health protection standards, equipment appearance and the surrounding environment of small differences in the levels of ionizing radiation. So we can see the results by detecting X-ray luggage inspection system in the absence of damage situation is not cause physical harm to airport staff and past travelers. Conclusion The test results shows;the radiation level and radiation dose of X-ray luggage inspection system are in line with the national health standards[1].%目的：本文的主要任务是研究和分析海南某机场X射线行李包检查系统辐射水平及剂量的基本情况。方法经过深入的分析,选取了采用目前为止最为有效的检测方法,即辐射剂量巡测仪法,此方法的检测水平符合《X射线行李包检查系统卫生防护标准》[2]。结果通过对机场所有型号的X射线行李包检查系统进行检测发现,其防护性能大体相同,各检测点的最大测定值均小于386.5,即小于卫生防护标准要求的水平,设备外表及周围环境的电离辐射水平的差异较小。所以通过检测结果我们可知X射线行李包检查系统在没有损坏的情况下是不会对机场工作人员以及过往的旅客造成身体上的伤害的。结论通过检测结果可知；X射线行李包检查系统辐射水平及剂量符合国家放射卫生标准要求[1]。
