Radon emanation from surface contamination

["Clement, Christopher" <clementc@aecl.ca>]

Radsafers:

I'm interested in interpreting measurements taken with a pancake Geiger
on radium contaminated surfaces.  This radium is old, so all of the
progeny have pretty much grown in, except maybe for the effects of radon
emanation.  Does anyone have any references out there which might give
me an idea of how much radon emanation may be taking place from this
type of contamination?
