Professor Cohen's radon studies have the advantage of looking at the

overall relationship of elevated radon and lung cancer. BEIR VI is a

constructed model (actually exponential as shown but intended to be a LNT

model) which depends on the linearized attempt to estimate the risk at zero

exposure using imprecise data. The radon doses to lung have considerable

uncontrolled uncertainties. The Iowa Study was not designed to have the

power to detect a radon risk that was overshadowed by the overwhelming

tobacco smoke risk and the radon doses to lung tissue have large

uncertainties.
