And, I agree with you. The problem is that it would be impossible to prove no 
effects at very low doses, since you cannot prove a negative . The 
counter-argument is that  very low dose effects, if any, could not be 
statistically discernible, but that doesn't prove that they don't exist.

I quite agree with you. My qualitative impression from many years of hospital 
work is that indeed the LNT assumption is seriously flawed. However, it seems to 
me that it is not my (our?) obligation to prove that no adverse effects exist at 
low dose-low rate exposures. It should be the obligation of the LNT's advocates 
to prove the opposite.
