	--My treatment of smoking is far more detailed than you imply. It

all boils down to the correlation between smoking prevalence and radon

levels. In my data there is a strong negative correlation between the

two, but not nearly strong enough to explain the discrepancy between my

data and LNT. In fact I show that even a perfect negative correlation does

not resolve the problem. All of the data I refer to are adjusted for

differences in smoking prevalence using the BEIR IV prescription
