Cosmic Ionizing Radiation Exposures on Aircraft and its Impact depending on some definite selected paths
Résumé
Abstract The assessment of the exposure to cosmic radiation onboard aircraft is one of the preoccupations of bodies responsible for radiation protection. Cosmic particle flux is significantly higher onboard aircraft than at ground level and its intensity depends on the solar activity. The dose is usually estimated using codes validated by the experimental data. In this paper, a comparison of the radiation dose on 30 one-way flights between Kuwait and Egypt was organized. A survey meter IMI Inspector Alert model (IA-V2) Geiger Counter, as well as personal dosimeter detectors [(EPD) and (RAD-60S / RADOS)], were used in this work. Good agreement was observed for instruments determining the different components of the radiation field; the mean ambient dose equivalent for the one-way flying was 8.4 µSv and Absorbed Dose rate was 3.6 µSv/hr. The agreement of values obtained for the total dose obtained by measurements and by calculations is very satisfying.
