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.
