	--your assumption is correct; in fact the decay products are much

more important

 daughters, and, it is true that light cigarette smoking does facilitate the

 removal of pollutants ( in this case think radon daughters attached to air

 particulates) perhaps, light cigarette smoking would have a positive benefit

 for diminishing radon daughter exposures and may account for the shape of

 Bernie Cohen's lung cancer - radon curve.



	--I have treated the issue of intensity of smoking in a paper

summarized and referenced in Sec. 4.4 of item #7 on my web site. It would

take completely implausible correlations of these variations with radon

levels to explain my results.
