[ RadSafe ] Is there a threshold for radiation effects?

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.
