本文介绍了一种在大气层中民航飞行高度上宇宙辐射有效剂量率和飞行航程中机组人员所受有效剂量的计算方法。用此方法计算了10km高空,87°E和116°E上,共计28个纬度的有效剂量率和6条飞行航线上宇宙辐射有效剂量,计算结果和美国联邦航空署的CARI-6算法的结果进行了对比,相对偏差在15%之内。此方法可用于航空公司对飞行人员的辐射防护管理。
A method for calculating cosmic radiation dose and dose rate to aircrews in atmosphere is presented in the paper. The effective dose rates from cosmic radiation for 28 geographical latitudes on geographical longitude of 87°E and 116°E at altitude of 10 km, and the cosmic radiation doses of 6 round trip flights were calculated by the method. The maximum difference between calculated results by the method and CARI-6 of Federal Aviation Administration is within 15%. The method is applicable to radiation protection management for the airline.
