FIGURE 2-4. ISLANDS REQUIRING PLUTONIUM CLEANUP PROCEDURES, soil on this island.) Case 3 was preferred based on the premise that safeguarding the Enewetak people from harmful radioactivity was of prime importance, and it was uncertain that Case 4 or Case 5 actions would be effective in reducing exposure potentials so that more of the northern islands could be used. Case 4: Same cleanup and disposal as Case 3 plus removal of 239,000 cubic yards of soil from Enjebi and replacement with imported soil; same island use as Case 3 plus use of Enjebi for residence and somecontrolled agriculture. This case was rejected because predicted doses from the proposed use of Enjebi exceeded AECcriteria and because of the great I
