“…From Figure 3, the public/prenatal limit can be exceeded in 100 hours of flight time. For high-latitude and polar flights, the dose equivalent rate is on the order of ∼ 10 uSv/hr (Copeland et al, 2008;Dyer et al, 2009;Mertens et al, 2008;). An accumulated 100 hours of flight time can be accrued from 10-20 international flights with roughly 5-10 hours of flight time per flight.…”

“…At 15 km over the polar region, the SEP exposure rates are greater than the GCR exposure rates by about a factor of five. Due to a substantially larger number of >100 MeV protons during the January 2005 storm event, the peak polar SEP effective dose rates are significantly greater during the January 2005 event compared to the Halloween 2003 storm period (Copeland et al, 2008). Before calculating radiation exposure along specified flight paths, it's constructive to examine a sample of effective dose rate profiles at different cutoff rigidities from our pre-computed database previously described for SEP event 3.…”

“…Currently, the above models calculate SEP atmospheric radiation exposure post-storm on a case-by-case basis, although PC-AIRE incorporated low-earth orbit measurements to develop a simple extrapolation to SEP events (Lewis et al, 2002). Recently, Copeland et al (2008) calculated adult and conceptus aircraft exposure rates for 170 SEP events for years 1986-2008 using the Monte Carlo MCNPX transport code.…”

“…However, aircrew are the only occupational group exposed to unquantified and undocumented levels of radiation. Furthermore, the current guidelines for maximum public and prenatal exposure can be exceeded during a single solar storm event for commercial passengers on intercontinental or cross-polar routes, or by frequent use (∼ 10-20 flights per year) of these high-latitude routes even during background conditions (AMS, 2007;Copeland et al, 2008;Dyer et al, 2009). …”

“…Estimations of the additional radiation exposure during ground level enhancements range from a few micro-sievert up to a few milli-sievert (e.g. Dyer et al 2007;Copeland et al 2008;Matthiä et al 2009aMatthiä et al , 2009bBütikofer & Flückiger 2011).…”

In addition to the omnipresent irradiation from galactic cosmic rays (GCR) and their secondary products, passengers and aircraft crew may be exposed to radiation from solar cosmic rays during ground level enhancements (GLE). In general, lowering the flight altitude and changing the flight route to lower latitudes are procedures applicable to immediately reduce the radiation exposure at aviation altitudes. In practice, however, taking such action necessarily leads to modifications in the flight plan and the consequential, additional fuel consumption constrains the mitigating measures. In this work we investigate in a case study of the ground level event of December 13th 2006 how potential mitigation procedures affect the total radiation exposure during a transatlantic flight from Seattle to Cologne taking into account constraints concerning fuel consumption and range.

Solar energetic particles (SEPs) sometimes induce powerful air showers that significantly increase the radiation dose at flight altitudes. In order to provide information of such a space radiation hazard to aircrew, a forecast model is developed for WASAVIES (Warning System of Aviation Exposure to SEP), based on the focused transport equation of solar protons and Monte Carlo particle transport simulation of the air shower. WASAVIES gives a simple and fast way to predict the time profile of dose rate during ground-level enhancements.
