RE: Dose Rates vs. Altitude

["Tonry, Louie L MAJ" <Louie.Tonry@se.amedd.army.mil>]

One time I flew from Germany to Tel Aviv.  I took a pressurized ion chamber
with me to prevent damage in the non-pressurized hold of the plane.  On the
tarmac, the exposure rate was about 35 uR/hr, at 36,000 ft, the exposure was
about 180-200 uR/hr.  I was supprised at the difference but not about the
radiation exposure.

I
Asearch of the RADSAFE archives (see bottom of page) under threads provided
40 hits using

exposure during cross country flights

Using "exposure during cross country flights"  provided 11 hits but took a
little longer.

If you do the search you may want to see the Consumers Union (Consumer
Reports) Medical Newsletter comments on this.  This can be found in a
posting of mine included with Ruth Weiner's posting of 11 May 1999.
