Objective. To calculate individual annual cosmic radiation effective dose for monitored flight personnel. Method. With the help of aircraft flight information from flight performance manual, software CARI-6 developed by U.S. Federal Aviation Administration was used to calculate the effective dose of galactic cosmic radiation along the air lines, and to calculate the effective dose rate on the ground in Urumuqi, then individual annual cosmic radiation dose on flight personnel was estimated from the data calculated by CARI-6. Result. The annual cosmic radiation dose on the ground at Urumuqi was 0.420 mSv a-1. The average effective dose rate of all flights of Xinjiang Airlines from 1997 to 1999 was 2.381 microSv h -1(0.33-3. 64 microSv h-1). Average annual cosmic radiation dose on flight personnel was 2.193 mSv a-1 (0.887-4.419 mSv a-1). Conclusion. Annual individual doses of all monitored flight personnel are well below the limit 20 mSv a-1 recommended by International Commission on Radiological Protection (ICRP).
目的。计算受监测飞行人员的个人年度宇宙辐射有效剂量。方法。借助飞行性能手册中的飞机飞行信息，使用美国联邦航空管理局开发的软件CARI - 6计算沿航线的银河宇宙辐射有效剂量，并计算乌鲁木齐地面的有效剂量率，然后根据CARI - 6计算的数据估算飞行人员的个人年度宇宙辐射剂量。结果。乌鲁木齐地面的年度宇宙辐射剂量为0.420 mSv a-1。1997年至1999年新疆航空公司所有航班的平均有效剂量率为2.381微Sv h -1（0.33 - 3.64微Sv h-1）。飞行人员的平均年度宇宙辐射剂量为2.193 mSv a-1（0.887 - 4.419 mSv a-1）。结论。所有受监测飞行人员的年度个人剂量均远低于国际放射防护委员会（ICRP）建议的20 mSv a-1限值。
