Re: Benchmark for CERCLA comparison -Reply
There is some disageeement between EPA and NRC on dose values. NRC uses the 25 mrem (all pathways), while the EPA has a position that 15 mrem (all pathways) equates to approximately 1e-4 risk under CERCLA. The application of CERCLA requires the risk based approach where there are no existing values (ARARs).
