The Air Crew Cosmic Radiation Effective Dose Calculation Using CARD

In order to monitor the cosmic radiation exposure level onboard aircraft in accordance with the national standard about radiation safety, a computer system CARD has been developed using to calculate cosmic radiation effective dose in flight. In this paper, the principle of development, structure and function of the CARD were described. The cosmic radiation effective doses received by aircrews in flight on some routes were calculated using the CARD. The results were compared with the data calculated using the CARI-6 and EPCARD, both flight dose computation system were developed by FAA (USA) and GSF (Germany), respectively. The agreement between the data obtained with the CARD, CARI-6 and EPCARD is within limit recommended by ICRP.
