Iit. TRANSURANICS* IN SURFACE** SOIL Based upon a study of the history of test operations, upon the data reported in NVO-140, and upon radiological measurements made during the cleanup project, it was concluded that no 1/4 hectare average is greater than 125 pCi/gm. The island average is determined to be 95 pCi/pem. 1t is therefore concluded chat the transuranics classification should be Food Gathering. IV. TRANSURANICS IN SUBSURFACE SOIL Based upon a study of the history of test operations, upon soil profile data reported in NVO-140, and upon the results of the Fission Product Data Base Program, a pridded subsurface sampling plan was implemented to delineate the boundary of each area exceeding 160 pCi/gm. No such area exceeds 1/16 hectare. Authorized Department of Energy Representative *For the purpose of this certification, the term “transuranics" is defined as those radionuclides measured and calculated by the ERSP to guide the Enewetak cleanup, i.e., °38Pu, 239pu, 240pu, and 24 lan **Surface, in this context, refers to the Layer of soil observed by the in situ detector in its normal measuring position. It is generally taken as approximately 3 cm in depth. 3-2 FIGURE 7-112. CERTIFICATION FOR ISLAND BELLE (Continued) 346
