Abstract

To estimate the cosmic radiation exposure level at civil aviation altitude, a method applied to calculate cosmic radiation effective dose rate in aerosphere from altitude of 5 km to 18 km presented in this paper. The effective radiation dose rates calculated using the method compared with results of cosmic radiation dose calculation system CARI-6 and EPCARD for various latitudes and longitudes, the agreement is within 15%. The numerical results of radiation dose rates at specifically locations in atmosphere by using the method are exact in the limit of ICRP 60.
