RE: LNT models -Constancy of Radon levels over time??

["Grimm, Lawrence" <LGrimm@ADMIN.UCLA.EDU>]

Perhaps Drs. Fields or Cohen can answer this:

In an EPA training session for Radon, I saw a graph/study that indicated
that it made no difference whether a house was energy efficient(tight
construction) or inefficient (older, looser construction)with regards to
Radon levels and all other factors being equal.  I carefully questioned the
instructor, because the EPA literature always indicates that Radon levels
are higher in an energy effiecient home.  So which is it?  Is the EPA
literature perpetuating a myth (my thoughts when the instructor insisted the
graph was accurate) or does it make a difference?
