Interesting. Consider NCRP 138 - Management of terrorist events
involving radioactive material, Sect 8. Dose limitations and guidance,
part 3 - Exposure Guidance for Emergency Responders? It cites NCRP 116
recommends that exposures should be limited to 0.5 Sv effective dose and
5 Sv skin dose (p. 96) where possible.

Subject: [ RadSafe ] Dose to Emergency Responders


I'm looking for a regulatory citation that states the allowable dose
limit to emergency responders in an accident involving radioactive
material. I took a hazmat emergency responder training course yesterday
and they said 25 rem was the limit, but couldn't cite any regulation to
back that up. I've seen in 10 CFR 50.67 where the source term in an
accident at a power plant can be no more than 25 rem, under various
circumstances, but I don't think that applies. 

Can anyone point me in the right direction?

Thanks in advance!
