Radiological criteria for determining acceptable remedical actions at radioactively contaminated sites on the Oak Ridge Reservation are presented in this report. The proposed criteria address protection of human health and man`s exposure environment but do not address protection of nonhuman biota. In addition, the criteria do not address potential exposures to nonradioactive hazardous chemicals that might be present at contaminated sites; however, as discussed, the protection principles on which the proposed radiological criteria are based could be used to determine acceptable remedial actions for carcinogenic hazardous chemicals. An important rationale for the proposed remedial action criteria is that many of the contaminated sites of concern were used for deliberate disposals of radioactive waste, principally low-level waste, or the sites contain radioactive materials similar in composition and potential hazard to many low-level wastes. Indeed, the basis for this proposal is the notion that remedial actions at radioactively contaminated sites on the Oak Ridge Reservation should achieve risks to human health consistent with current standards for ongoing, permitted disposals of low-level radioactive waste at Oak Ridge and all other United States Department of Energy (DOE) sites.
