NRC dose limits are 5 rem for occupational workers and 100 mrem to the
public. These limits are reasonable and readily achievable dose limits
regardless of LNT or hormesis. Appendix B is based on ICRP 30 and should be
updated regardless of dose response theory.
The EPA has limits of 4 and 10 mrem on the books. Those limits are not
reasonable regardless of the LNT argument.
OSHA uses 1950’s MPC guidelines of ICRP 2. They should be discarded
or modernized regardless of LNT.
Reduced limits due to hypothetical multiple pathways and/or overly
conservative pathway modeling is very expensive regardless of LNT or hormesis
theory.
Just my personal thoughts,
