Barely measureable increased risk. If you really want to worry about radiation, a big solar flare might be a good time to call out sick... you can get a couple years worth in a couple hours.
Again, circadian flop is the biggy IMO.
Cracks me up - years ago a pilot posted "I told the Captain about the solar flare and convinced him that we should fly to S. America at (IDK, FL280? FL310?). It was a non-ionizing solar flare. He had more risk from shaving compared to the solar flare. The type of flare matters.
Or the 'aviation expert' who testified in court ($$$) as such. Flew around S. America and wouldn't go higher than FL330(?). Had the same rule for flying to Europe - not above FL330. Head shaking about 'experts'......you can't get as much mSv's going to S. America at FL410 as you can going to Europe at FL330.
Don't take my word for it. The CAMI-6 radiation calculator will allow you to see the data for specific city pairs in a given month. It lags the calendar by about 2 months. S. America to the U.S. mSv exposure at FL330 was something like FL230 (??) going to Europe.
