Radiation dose of aircrews during a solar proton event without ground-level enhancement
A significant enhancement of radiation doses is expected for aircrews during ground-level enhancement (GLE) events, while the possible radiation hazard remains an open question during non-GLE solar energetic particle (SEP) events. Using a new air-shower simulation driven by the proton flux data...

| description | A significant enhancement of radiation doses is expected for aircrews during
ground-level enhancement (GLE) events, while the possible radiation hazard
remains an open question during non-GLE solar energetic particle (SEP)
events. Using a new air-shower simulation driven by the proton flux data
obtained from GOES satellites, we show the possibility of significant
enhancement of the effective dose rate of up to
4.5 μSv h<sup>−1</sup> at
a conventional flight altitude of 12 km during the largest SEP event that
did not cause a GLE. As a result, a new GOES-driven model is proposed to give
an estimate of the contribution from the isotropic component of the radiation
dose in the stratosphere during non-GLE SEP events. |
