Abstract. The radiation dose rates at flight altitudes may be hazardously increased during solar cosmic ray events.
Within the scope of this paper we investigate the total accumulated radiation doses, i.e. the contribution of galactic
and solar cosmic rays, during the two extreme solar cosmic ray events on 29 September 1989 and on 20 January 2005 along
selected flight profiles.
In addition, the paper discusses the consequences of possible solar cosmic ray flux approximations on the results of the
radiation dose computations.
