Setpoint..thanks for the link.

Back in the day most of the mil weren't at very high levels long enough for cosmic radiation to be an issue, and in my military days we certainly didn't clock up anything like the hours at high level the airline guys did. That said there will always be exceptions like the U2.
Concorde was a game changer in some ways in being at very high level for relatively long continuous period but I believe there was only one recorded instance of a descent being needed because the alarm went into the red...anyone confirm/deny?
As far as cancer risks are concerned, under pinning all this is the happy fact/statistic that about 30% ( yep, about 1 in 3 ) of the general non flying ground level living and working population will at some time in their lives suffer from cancer. Despite the inevitable anecdotes the general informed opinion seems to be that any small increased incidence of cancer due to radiation exposure in flight is almost immeasurable against the general background incidence.
Yet again, sorry for the thread drift.
