[ RadSafe ] Airlines diverting polar flights due solar storm

[Jim Darrough]

Neutrons? Did not know that there were neutrons coming in a CME. I thought
that there were mostly Protons.

Thanks for the interesting graph of the roentgen "dose" (photons in air).
Please note though that 50 - 75% of the *dose equivalent*, or equivalent
dose, for those outside the USA,  at cruising altitude, originates in
neutrons.

Cheers
