314 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL Soil Cleanup Planning The Director, DNA requested that DOE examinethe possibilitv of not cleaning Boken and Lujor to 160 pCi/g and identifying patterns of living that could be adopted for those islands other than quarantine. DOE representatives agreed to have this done. Dr. W. P. Wood, of EPA’s Radiation Programs and its representative at the conference, pointed out that DOE/DOD acceptance of the 40-80-160 pCi/g criteria should not imply EPA approval and that, once the plan for soil removal was established, EPA would desire to examine that plan. The Director, DNA stated that he understood that there was no EPA biessing, but he also pointed out that Enewetak really did not come underthe draft EPA guidelines. The Director, DNA decided to accept thecriteria recommended by the Bair Committee and DOE as the standards for contaminated soil cleanup. This acceptance was contingent upon the Bair Committee and DOE developing more precisely the status of islands (e.g., Boken or Lujor) which might end up being cleaned to below 400 pCi/g, but not down to the 160 pCi/g criteria recommended by the Bair Committee for food-gathering the people there were « coconuts than DOE had strontium and cesium in!

The dose assessment indicated that living on islands having surface transuranic levels which averaged 40 pCi/g, growing crops on tslands which averaged 80 pCi/g, and visiting islands which averaged 160 pCi/g could result in a dose of about 13 millirads for transuranics alone, over four times the proposed new EPA guideline of 3 millirads per year for the U.S. Doses from strontium and cesium in the drinking water, coconuts, and other local food were not considered since it was assumed that no one would be permitted to live on Enjebi until after those elements decayed to acceptable levels. By this time, everyone was aware of the Bikini cleanup and resettlement problems. Mr. McCraw, of DOE, stated that Bikini was typical of what could happen in the Marshall Islands.
