	--Since LNT uses a linear relationship between lung cancer and

radon, of course I use it to see if LNT predicts the observed results. How

else could I possibly test LNT? If that is what Lubin means, how could he

possibly criticize it? I assumed that he was referring to my treatments of

confounding factors.
