Abstract:
:Because the doses received on-board aeroplanes are now monitored to fulfil legal requirements in some countries, including the European Community, the models to calculate doses received during solar events have left their purely academic status to become a part of operational systems as well. The present work considers parameters of importance to determine the doses received during solar events: spectral characteristics of the solar particles and anisotropy of primary particles and their variations in the course of the Ground Level Enhancement (GLE). Precise determination of both, using all the information available from the worldwide neutron monitor network, being a long process, simpler methods are proposed to calculate rigidity spectrum exponent and to correct the models for anisotropy. A recent GLE of large intensity, having occurred on 20 January 2005, is used both as an example of an important event and because the necessary data were collected within a few days, showing that the above methods, in addition to their own interest, have also an operational potential.
