5.Methods With the help of aircraft flight information from flight performance manual, the effective dose rate of galactic cosmic radiation along the airlines in Xingjiang area, and the effective dose on the ground in Urumuqi were calculated using software CARI-6, then individual annual cosmic radiation dose received in flight personnel was estimated.
6.[Methods] With the help of aircraft flight information from flight performance manual for the years 1997-1999,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 the annual effective dose rate for three years,the individual annual cosmic radiation dose on flight personnel was estimated.
