Validation of Modelling the Radiation Exposure due to Solar Particle Events at Aircraft Altitudes

Dose assessment procedures for cosmic radiation exposure of aircraft crew have been introduced in most European countries according to the corresponding European directive and national regulations (1). The radiation exposure due to solar particle events is still a matter of scientific research (2). Several in-flight measurements were performed during solar storm conditions. First models to estimate the exposure due to solar particle events have been discussed. Recently EURADOS (European Radiation Dosimetry Group, http://www.eurados.org/) has started to coordinate research activities in model improvements for dose assessment of solar particle events. This paper describes the outline and preliminary results of a work package related to the European project CONRAD (Coordinated Network for Radiation Dosimetry) on complex mixed radiation fields at working places. The major aim of a subgroup of that work package is the validation of models for dose assessment of solar particle events, using data from neutron ground level monitors, in-flight measurement results obtained during a solar particle event and proton satellite data
