of the FRC annual standards for evaluation of the many cleanup and rehabilitation alternatives at EKnewetax Atoll. This is not to be viewed as an attempt to establish new standards but is considered to be a necessary 2recaution in the application of current standards. The following values apply for evaluation of alternatives: “Whole body . 6 6 0 ee ee ee ew we ee 9025 en/yr Bone marrow « « 6 « 6 « © © © ee ee 0625 Rem/yr BONE 2 ww ew we ee ww ww ww ew oe M75 Rem/yr Thyroid oc ew ee we ew ww we ww ew 1475 Rem/¥t The Task Group recommends use of 190 percent of the TRC RPG's to evaluate post cleanup and rehabilitation and post return conditions wherein iftrect measurement of levels of radiation and radioactivity in foods and in people are made. Under such conditions, dose estimates should be subject to much less uncertainty. The requirement is to assure that exposures are well within the FRC standards. See Section A. of this Appendix for the FRC RPG's. Tue eriteria for evaluating gonadal exposures at Enewetak Atoll should be 4 rens in 30 vears. The requirement is to assure that long term exposures vill be well within this criteria. The Task Group feels justified in using 30 percent rather than 50 percent of the FRC Standard since there will be ample time to verify exposure estimates using actual sampling of the diet and time to follow the chansing pattern of exposures of people. 1114-15 Sie
