Hi Jim,
Exposure, as you know, is a function of altitude, time at altitude,
latitude and as with the B787, structure.
So if you're a long- haul pilot flying over the poles (eg. Asia to
the USA) in a B787 the radiation dosage should be higher.
Long-haul airline unions have been trying to append some science to
the debate for a good decade or so but the big airline corporations
aren't about to do anything that will cost either money or
productivity or open up any pathway that may ultimately lead to
compensation. Small airlines can barely afford to survive let alone
give away productivity on poorly articulated issues like radiation.
The science is about as well defined as that surrounding climate
change. The science behind fatigue and flight time limitations is
finally on the front burner but the radiation issue has barely been addressed.
I guess the argument with passengers is that they are infrequent
travelers compared to aircrew so not worthy of consideration.
I remember years ago doing my annual medical with the Qantas doc,
Ion Morrison, who in a throw-away comment said that he was concerned
by what he saw as a serious uptrend in tumors amongst flight crew.

Then again just this morning:

I'd worry more about the circadian disrythmia than radiation for
airline crews. Likely this has an effect on the body's immune system.
