RE: Dosimeters and Airport Security



When I worked at Mare Island, a situation like that would happen occasionally in one of the facilities.  If the interior air sample of radon progeny reached 3 times the outside air, we had to exit the building.  This may have been motivated by a concern that "real" airborne contamination might be masked, rather than from the actual exposure.

Well, here is hat eater.......an employer that requires a person to work in a building that enhances naturally occurring radon emanations is required to account for the internal exposure, right?

Therefore, an employer that requires an employee to travel, say by jet aircraft at high altitudes, is supposed to account for the high altitude exposure (not natural background, per se, but maybe enhanced by the high altitude of the flight) and the additional exposure from penetrating x-rays at the airport....really?


I think, and I'm not speaking for any agency, that the high altitude exposure would be considered part of the "natural background," but that the x-rays at the airport would not, although, if anyone actually gets a measurable exposure from the x-ray machines at the airports while passing through security, even a dozen times a month, I'll eat my hat.

Fortunately, no matter what the case, I do not own any hats.
