RE: Flight Attendant Question

Kai,



 



I recall that a significant portion of the dose equivalent when flying comes

from neutrons. A normal GM detector would not detect the neutron flux.



Is Bob Barish listening?

Subject: Flight Attendant Question



 



Hi folks,



 



I received a (rather long) question from a fight attendant. Most of it I can

answer myself except:



 



Would an energy compensated Geiger Tube based instrument give a reasonable

indication of dose rate inside an airplane?



 



I think if most of the interactions are from secondary photons, the reading

may be OK. If the most of the counts are from charged particles, the reading

will probably not correspond to dose.



 



Any thoughts?



 



Kai
