摘要
目的探讨一种可用于民航飞行人员宇宙辐射有效剂量率估算的简便算法。方法在PC机Win dows操作系统用ObjectPascal语言 ,根据本文介绍的简便算法编制程序计算不同海拔、不同地理位置的宇宙辐射有效剂量率 ,并将计算结果与CARI 6和FLUKA的结果比较。结果简便算法计算结果与CARI系统和FLUKA计算结果很一致 ,在与CARI比较的 3组数据中 ,误差在 2 5 %之内的数据比例分别是 76% ,71 %和 1 0 0 %。在与FLUKA比较的一组数据中 ,误差全在 2 0 %之内。结论简便估算法可用于海拔为 70 0 0 2 0 0 0 0m的飞行空间的宇宙辐射有效剂量率估算。
Objective To study a simple method for estimating cosmic radiation effective dose rate for aircrew. Method Using a new program by written in Object Pascal language on PC in windows operation system on the basis of an algorithm designed in this paper, cosmic radiation effective dose rates at various altitudes and latitudes were calculated and compared with those obtained by using CARI-6 and FLUKA. Result The calculated results by using the simple method agree remarkably with those calculated by using CARI-6 and FLUKA, in three groups of data compared with CARI-6, differences are within 25% for 76%, 71% and 100% of the data respectively; in the group of data compared with FLUKA, differences are all within 20%. Conclusion The simple method is applicable in estimating cosmic radiation effective dose rate for flight altitude of 7 000 m to 20 000 m.
