Dear RadSafers I have seen guidance for doses "limits" in an emergency, written in several DOE documents: 25 rem for lifesaving, >25 rem for lifesaving with fully informed volunteers. I am told that similar guidance has been issued by other US government agencies, perhaps the EPA. Can anyone tell me where this is written? Thank you, mike "Shlala gashle" (Zulu greeting meaning "stay safe") mike
