Re: Exposure during Cross Country Flights

[HardyKPhys@aol.com]

There are two FAA reports which give radiation exposure estimate for typical 
airline routes.  One that I have is FAA Advisory Circular AC.No. 120-152 
titled "Radiation Exposure of Aiir Carrier Crewmembers" issued in 1990.  The 
other was a followup report DOT/FAA/AM-92/2  titled Radiation Exposure of Air 
Carrier Crewmembers II issued in 1992.  I do not know if there have been any 
further revisions of these documents.  There was also a NCRP report on 
exposure risks from air travel sometime in 1995, but I could not locate it in 
my files.  I enjoy taking small pocket type readition monitors on airline 
flights and watching the count rate go up when the plane gets above 10000 
feet.
