“Actions assumed for specific ranges of Pu concentration are tabulated as follows:
Level
1
2
Plutonium
Concentration
> 400
40<c < 400
Action
Soil removal by repetitive scraping
Individual case consideration
All other islands have Pu concentrations < 40 pCi/g and do not require cleanup action.

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
