Dose characteristics of cosmic rays at airways high-altitude aeroplanes

The evaluation of ionizing radiation levels in the atmosphere, that is evaluation of dose equivalent rates created by various cosmic ray components at flight altitudes of modern passenger acroplanes, determination of their dependence on the altitude above the sea-level and locality latitude is performed. The energy distribution of dose equivalent rate, distribution of dose equivalent rate by particle type as well as the dependence of total equivalent dose rate of galactic rays on the solar activity level. The results are presented in graphical and table forms
