Abstract:
The results of probing the radiation environment on board different civil aviation planes with singletype detectors (nuclear emulsions), with particular emphasis to the cosmic radiation flux measured inside aircraft, are presented. The measurement results make it possible to find the absorbed and equivalent doses induced by the cosmic radiation neutrons and charged particles.
