Compare to Dental X-Ray
I went to the dentist a couple of hours ago, and was talking with the hygienist about X-rays. She made the comment that the X-rays used in dentists offices is MUCH less than it was only a few years ago (they now use electronic sensors, not film like they used to). I then pointed out that flying long flights (internationally) exposes you to LOTS more stuff than the simple X-rays you get on a yearly basis. The information I used related to high altitude exposure, but when you add in this little stuff, it can get excessive at times. When you only fly a few flights a year, the integrated exposure isn't very much, but if you are employed as part of the flight crew (main cabin, or cockpit) you get several trips in a month (sometimes over 4 long flights a week!) and for those people, it can add up.
So, to really find out, we need some silly "in-depth" study, when collecting the data might be as easy as taping a piece of film (suitably shielded from light) to the side of the plane with duct tape.
Then we get OSHA regulations and prop 65 warnings galore to scare the public!
