We have calculated by using CARI-7A the effective and ambient radiation dosesabsorbed by a reference human phantom inside aircrafts with cruise speed, andaveraged ascent/descent rates as presented by real airplanes such as: Airbus380, Boeing 777, 787, Hercules C-130 and Twin Otter DHC-6, in a sample offlight aerial routes in a range of flight levels. In the sample, fifteen routesare between the longest non-stop flight around the world, where four flightspass over the Arctic and we have considered one air route involving theAntarctica with two additional special cases. The Earth curvature based onmodel WGS84 was taken into account for every point in each route by using theINVERSE3D software. Then we constructed radiation dose charts according to theICRP-103 conditions by using the radiometric results coming from the CARI-7Asimulations. These charts present the effective absorbed radiation dose as afunction of flight level and flight time in a year of normal operations of thecrew as recommended by the FAA. We have also characterized geographically andkinematically the cosmic effective radiation absorption rates at Earth'satmosphere in terms of the structure and order of polynomials in the altitude.From the flight with the leading rate of irradiation we found a thumb rule toestimate the effective absorbed radiation dose and the ambient equivalent dosethat gives a superior threshold for any flight of the sample and perhaps onEarth, valid in altitude interval [20000, 50000] ft.
