	--If you don't understand that the BEIR Reports use a liinear

relationship between lung cancer and radiation exposure, there is no point

in discussing these matters with you. What do you think the LNT debate is

all about?

	--This is proven with rigorous mathematics in my 1995 paper,

starting with the BEIR IV formula.
