A transport code analysis using the Monte Carlo N-Particle eXtended code, MCNPX, has been used to propagate an extrapolated particle spectrum based on satellite measurements through the atmosphere to estimate radiation exposure during solar particle events at aircraft altitudes. A comparison was made between the model predictions and actual flight measurements taken with various types of instruments during Ground Level Event 60. A computer-code has been developed to implement the model for routine analysis. Current research is focused on introducing a new anisotropy model that uses neutron monitor responses and pitch angle data to identify anisotropy and correct for it.
