Re: LNT theories - Which model??

Prof. Cohen could not have tested the BEIR VI model since it predates his
work and is apparently actually an exponential model rather than an LNT
model. The BEIR IV linear model depends on WLM exposures rather than radon
concentration, so it would require some modification.

I will have to reread Cohen's paper to give a more precise answer to your
question, which I will do tomorrow. 

Perhaps Dr. Cohen can comment on the way in which the linear model that he
shows on his plots (and tested) was derived.
