(Slightly off the mark, but I believe that the same EPA that demands the referenced risk of 1E-4 or less, also uses 2% per Rem (0.02 times the population exposed) to calculate that additional death rate from cancer. I'm quite surprised at such a high figure!

If the EPA considers the annual dose to be one Rem and it occurs every year for a 50 year lifetime for adults, that's 50 Rem times 0.0004/Rem cancer risk (from ICRP-60) or 0.02 or 2% lifetime risk.

A simplistic linear model using LNT makes the math really easy for EPA!
