Flying Flouroscopy

I guess I never thought about it, but the radiation that you absorb during a cross-country flight is roughly equivalent to that of a chest x-ray. A lot of people are warning that we should obviously limit unecessary xrays, should we limit flights? Proabably not worth much worry. Fact Sheet here.

Of course, we also absorb an equivalent amount in about 10 days just lounging around in our homes, so I'm not terribly worried. The things you learn on the web!
