High Altitiude Exposures

[mattw@eml.doe.gov (Matthew Williamson)]

Chat has been down to a minimum.  Everyone must have taken an early holiday.

A while back, a thread ran on exposures to flight attendants and pilots.
The mean exposures were between 1-3 mSv/year.  Hmm...this sounds like
occupational exposure.  In the world of DOE, these individuals must be
monitored for exposure because they exceed 100 mrem/year under typical
conditions (10CFR835).  

Where is the dosimetry?  Where are the exposure records?  Navy Nukes are
badged...aren't they?

I had the luck of living next to a couple of flight attendants
(stewardesses-not politically correct).  No badges...no RAD training...  How
do these folks get by the regulators?

Flying the Concord surely allows a larger dose.  I understand that it is
less time, but the flight is much higher.  Now we're talking high energy
physics (>20Mev neutrons and much higher energy cosmic rays-accelerator type
stuff).

Do I fly or take the train with John Madden and his All Madden Team?
