Re: Dose Rates vs. Altitude

[Richard Smart <R.Smart@unsw.edu.au>]

Radsafers,

Dose rate varies with latitude as well as with altitude.  I recommend that
you look at one of the Information sheets produced by the New Zealand
National Radiation Laboratory at
http://www.nrl.moh.govt.nz/sheets/is19.html.  This includes a table of dose
rates for different altitudes at 7 bands of latitude, together with
estimates of annual doses for New Zealand flight crew.  

Regards

Richard
