Re: Risks of low level radiation - New Scientist Article

["Raymond A. Hoover" <rayhoover@HOTMAIL.COM>]

That is the problem with this whole argument.  One cannot conclusively 

disprove a negative.  One has to look at the preponderance of the evidence 

and then draw a conclusion.  Personnally, I think the fact that the only 

support for LNT being inferred and that studies such as Dr. Cohen's must 

lead one to the conclusion that LNT is incorrect.



But of course that is just my opinion.
