Cohen's ecologic studies

["R. William Field" <bill-field@uiowa.edu>]

Dr. Raabe,

I do not think Dr. Cohen has been clear on this issue regarding his
ecologic studies.  

Maybe, Dr. Cohen will respond and settle this question.  I will pose the
question to him.

Dr. Cohen,

Do you think your ecologic studies have the power to assess the lung cancer
risk/benefit posed by residential radon exposure?
