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 various codes is presented, some of them are used routinely, to assess the dose received by the aircraft crew caused by the galactic cosmic radiation. Results are provided for periods close to solar maximum and minimum and for selected flights covering major commercial routes in the world. The overall agreement between the codes, particularly for those routinely used for aircraft crew dosimetry, was better than + + + + +20 % from the median in all but two cases. The agreement within the codes is considered to be fully satisfactory for radiation protection purposes.

“…The value of Ze/ (Z is the charge number) corresponds to the average energy loss of cosmic rays inside the heliosphere. Here we consider the nucleonic ratio of heavier particles including a-particles to protons in the interstellar medium as 0.3 (Gaisser & Stanev 2010) similarly to Kovaltsov et al (2012). The model with the corresponding parametrization of LIS provides very good fitting of the measured spectra (for details see Usoskin et al 2005, and references therein).…”

“…The model with the corresponding parametrization of LIS provides very good fitting of the measured spectra (for details see Usoskin et al 2005, and references therein). For the computations, a realistic mass composition of the primary GCR (Gaisser & Stanev 2010) is assumed, where the contribution of heavier species is scaled to that for a-particles (Usoskin & Kovaltsov 2006;Mishev & Velinov 2011;Kovaltsov et al 2012). …”

A numerical model for assessment of the effective dose and ambient dose equivalent produced by secondary cosmic ray particles of galactic and solar origin at commercial aircraft altitudes is presented. The model represents a full chain analysis based on ground-based measurements of cosmic rays, from particle spectral and angular characteristics to dose estimation. The model is based on newly numerically computed yield functions and realistic propagation of cosmic ray in the Earth magnetosphere. The yield functions are computed using a straightforward full Monte Carlo simulation of the atmospheric cascade induced by primary protons and a-particles and subsequent conversion of secondary particle fluence (neutrons, protons, gammas, electrons, positrons, muons and charged pions) to effective dose or the ambient dose equivalent. The ambient dose equivalent is compared with reference data at various conditions such as rigidity cut-off and level of solar activity. The method is applied for computation of the effective dose rate at flight altitude during the ground level enhancement of 13 December 2006. The solar proton spectra are derived using neutron monitor data. The computation of the effective dose rate during the event explicitly considers the derived anisotropy i.e. the pitch angle distribution as well as the propagation of the solar protons in the magnetosphere of the Earth.
