We propose as a generally applicable de minimis dose for members of the general public (1) a principal limit on annual committed effectie dose equivalent averaged over a lifetime of 0.01 mSv (1 mrem) and (2) a subsidiary limit on committed effective dose equivalent in any year of 0.05 mSv (5 mrem). Existing methodologies for using a de minimis dose are reviewed to derive exempt concentrations of radionuclides in solid wastes for purposes of disposal, and a methodology for application to disposal on the Oak Ridge Reservation is presented. Difficulties in application are discussed with reference to a proposal for an exemption level for uranium in solid wastes of 30 pCi/g. Finally, we discuss existing methods for measuring the uranium content in bulk solid wastes, because such measurements probably will be required in exempting uranium-bearing wastes for disposal.
