Dr. Long,



In response to your question, yes I do believe radon causes lung 

cancer.  Others like the Surgeon General, American Cancer Society, 

etc support the position that radon causes lung cancer.  In fact, if 

you check it is listed as a Class A Carcinogen.

============================



It does at high doses/dose rates; does not at low doses/dose rates.



"Case-control" animal studies, where the cases actually have measured

doses!, demonstrate this with certainty. Before smoking (late 1800s)

lung cancer was very rare, and not affected by radon levels.



You just keep naming the self-serving Fed fraud group to make your case

- not. Never any science.
