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.
Best regards,
Brian DuRieu
