Radiat Prot Dosimetry. 2018 Aug 1;180(1-4):134-137. doi: 10.1093/rpd/ncx170.
Galactic cosmic-ray-induced air showers constitute the largest source of radiation exposure for aircrew and passengers. To facilitate the evaluation of effective doses received by this population, a database containing dose rates of various radiation components in the atmosphere was established; the parameterization accounted for altitude, geomagnetic rigidity and solar modulation. Energy spectra of secondary cosmic rays and effective dose rates were calculated using the FLUKA Monte Carlo code. An auxiliary MATLAB program with a graphical user interface was developed to estimate the aviation route dose through interpolation and integration. The dose calculator was benchmarked by comparing its predictions with data from other assessments. Finally, a set of representative flight routes of substantial interest in Taiwan was selected and evaluated.
银河系宇宙射线引发的空气簇射是机组人员和乘客辐射暴露的最大来源。为便于评估该人群所接受的有效剂量，建立了一个包含大气中各种辐射成分剂量率的数据库；参数化考虑了海拔、地磁刚度和太阳调制。使用FLUKA蒙特卡罗代码计算了次级宇宙射线的能谱和有效剂量率。开发了一个带有图形用户界面的辅助MATLAB程序，通过插值和积分来估算航空路线剂量。通过将剂量计算器的预测结果与其他评估数据进行比较来对其进行基准测试。最后，选择并评估了台湾地区一组具有重大意义的代表性飞行路线。
