II. SOIL CLEANUP A. GENERAL. ‘1. The only contaminated soil to be removed as part of Cleanup is that which is contaminated with plutonium and its decay products. A_ basicassumption of the Cleanup Pian is that the AEC Enewetak Radiologi- cal Survey (AEC Report NVO-140, Oct 73) located all significant areas of such contamination. The Survey did not investigate every "square inch" of the Atoll; however, a randcm~sampling method was employed which was biased to incrcase sampling frequency in areas suspected of being contaminated because they were previously surface ground zeros and/or in fallout patterns, and in areas which were considered likely to be inhabitated someday. Sufficient samples were taken and analyzed from other areas such thet the probability of any significant "hot spets” ” _—— a being missed is considerednegligibly’ small. In other words, the Survey will be accepted as an authoritative source for having identified all cee Tene areas potentially requiring plutonium-contaminated soil removal and no additional areas or "hot spots" are expected nor will any be searched forintentionally. Only if additional evidence is forthcoming will other areas be investigated for plutonium contamination. 2. Areas will be investigated as potentially requiring soil Cleanup onlyif the Survey reported them to have plutonium at concentrations greater than 40 pCi/g. Further, the numerical concentration Ra values reported in NVO-140 will be the deciding factor irregardless of
