RE: LNT has been disproved. Some scientists deny it.



John,

It may be defined as a regulatory concept.  But even NCRP 136 shows that

responses vary for cell line to cell line.  From organism to organism.  It

is easy to disprove biologically, but the issue is its use in regulation.

I disagree.  LNT is very well defined. How better can you define a 

quantity than to say it is a straight line on a graph of dose Vs 

cancer graph.  Many animal studies in NCRP Report No. 104 contradict 

LNT.



LNT was disproved by Frigerio in 1973 and much strongly disproved in 

many other cases described in Sohei Kondo's book Health effects of 

Low Level Radiation.

I think the best proof is the nuclear shipyard worker study and the 

100 years of British radiology.

Best wishes,  John Cameron
