In response to "Radio news - the current level of radiation while flying on a plane is equal to a chest xray." by CrankYanker

it's like 0.4mrem/hour of fly time, a chest xray is 5 or 6. either way you've got a couple hundred hours of fly time or a couple dozen chest xrays

before you're even getting close to the annual high-dosage for the general public, and even that's like an order of magnitude beneath what radiation workers get.

also, my radiochemist friend who makes the isotopes for a PET scanner in town says lead aprons make low exposure things worse. something about the high density of the lead attracting more radiation.
