@ The Federal Radiation Council (FRC) Radiation Protection Guides (RPG's) for individual and gonadal exposures are recommended as the criteria to be used in evaluating the various exposure radiation options. The numerical guidance therein should be reduced by the factors of 50% for individual exposure and 20% for ganadal exposure considering that exposures cannot be precisely predicted. The detailed rationale for these reductions is provided in Appendix III. The resulting guides for planning cleanup actions will then be: Whole body and bone marrow ~ 0.25 Rem/yr Thyroid -- --- 0.75 Ren/yr Bone --~ 0.75 Rem/yr GonadS -------<n- ne— 4 Rem in 30 yr S Pty wa ga +,: - + Lot ~. “ , - . eon, : .
