options. The numerical guidande tferein should be reduced by the factors of 50 percent for individual exposure and 20 percent for gonadal 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 Rem/yr Bone - 0.75 Rem/yr Gonads - 4 Rem in 30 yr Since there is no adequate scientific information which would support general guidance for cleanup of plutonium contaminated soil, | guidance can only be developed on a case-by-case basis using con‘servative assumptions and safety factors. With this in mind, the Task Group recommends the following for use in making decisions concerning 239 Pu cleanup operations at Enewetak: a. < 40 pCi/gm of soil - corrective action not required. b. 40 to 400 pCi/gm of soil - corrective action determined on a case-by-case basis* considering all radiological conditions. c. > 400 pCi/gm of soil - corrective action required. ASSESSMENT OF DOSES AND THE RESULTS OF ALTERNATIVE CORRECTIVE ACTIONS The Task Group approach for development of judgments and recommendations for the radiological cleanup and rehabitation of Enewetak was to consider a number of alternatives for exposure reduction that may be feasible. the procedure involved four steps: *See Appendix III for additional guidance. =5= Basically,
