The only twaddle worse than doctors talking about aviation is pilots talking about medicine
That might depend on what said pilot did in a previous career...
What's your professional opinion on the claim that a transatlantic trip is the equivalent of at least 1 chest X ray?
It's quite possible for a crew member to perform 30 - 40 return transatlantic flights a year - would you support the assertion that this is "equivalent" to 30 - 40 chest X-Rays a year? If not, why not?
( and can I crib your explanation for future use, seeing as I seemingly made a Horlicks of my initial effort
