Re: Dose received from air travel?

[G A Zabierek <GAZ@safety1.bham.ac.uk>]

David,
In the UK, the NRPB produce an "At-a-Glance Series" of posters.  In 
the 1994 Radiation Doses - Maps & Magnitudes poster there is an 
illustration covering Cosmic Rays showing the increase with altitude 
of dose received each hour.    
At 15 km (picture of Concorde) 10 microsieverts per hour
at 10 km (picture of B747)        5 microsieverts per hour
at  6.7 km (Himalayan peaks)   1 microsievert per hour
at  2.25 km (Mexico city)  - 
     1.6 km   (Denver)                  0.1 microsievert per hour
at sea level                               0.03 microsievert per hour

For UK the average dose at ground level is 260 microsieverts a year, 
with a range of 200 - 300 microsieverts.
