摘　　要：目的为了保障机组人员健康和飞行安全,研究开发宇宙辐射剂量计算机估算系统。方法先通过模拟和测量数据,根据给定日期、地理坐标和海拔计算剂量率,然后按照飞行信息计算航程有效剂量。结果用该系统计算的剂量率和航线剂量的数值结果满足国际放射防护委员会60号出版物的精度要求。结论该计算机宇宙辐射剂量估算系统适用于航空公司辐射防护管理。Objective To detect the applicability of a developed computer program for promoting radiation safety and the health of Chinese airline aircrew. Methods On the basis of dose rates in μSv/h at given date, geographic locations and altitudes obtained by measurement and simulation, and the estimated rates doses according to the information of flight profile, a computer program CAUCARD was developed. The effective dose rates for various latitudes at 10 km altitude, 87°E and 116°E longitude in Sept 2004 were calculated by CAUCARD and compared with those calculated by CARI-6 and EPCARD, and cosmic radiation effective doses along the air lines in Sept 2004 calculated hy CAUCARD were compared with those of CARI-6. Results The precision of dose rates and route close along the airlines calculated by CAUCARD can meet the demand of CARI-6. Conelusions The computer program CAUCARD for route dose estimation is applicable for aircrew radiation protection management of airline.
