This is just about impossible to answer definitively, as it all depends
on where each respondent places the x-intercept (threshold value).  It 
will also depend on whether you account for possible hormetic(sp?)
effects.  The only thing I can say for sure is that all of the non-LNT
models I've seen will give you a lower risk probability than LNT at 
low doses.
