RE: Risks of low level radiation - New Scientist Article

Otto,

I believe there were postings about soot or fine particles as being a cause

for lung diseases in cities.  Could this be the confounding factor for which

you are looking?

. . .

 Meanwhile, Colorado enjoys one of the lowest lung cancer rates in the

nation. In 1995

it was 49 the out of 51. Washington,DC, where radon concentrations are much

lower, had the highest lung cancer rate in 1995 (Am. Cancer Society, 1996).



Of course, it is always possible to say that some yet-to-be discovered

cross-level confounder could be causing the "apparent" disagreement with

LNT, but it does seem unlikely.
