Bill, I don't know what you mean by "directly examine."  Risk estimates are 

extrapolations anyway.  The Iowa study does not provide a list of individual 

exposures, which is what I would have thought was meant by "directly 

examine".  I really believe that to make your point you dshould publish the 

radon exposures of the non-smoikers in your cancer cohort, after correcting 

for secondary smoke.



Moreover, your assessment of radon exposure was hardly "direct."  The paper 

makes a lot of assumptions about times people spent at various rdon exposures.
