5. In reviewing the LLL preliminary dose assessment, Ed Bramlitt, DNA Field Command, questioned the calibration procedures used in the IMP's, specifically the soil composition used in calibration vs. the soil composition at Enewetak. (You may recall that the general issue of calibration is one which you have raised in the past). Indications from Las Vegas are that Mr. Bramlitt is correct, and that errors of 20-25% may have been introduced, the readings being lower than actual radioactivity levels. Until this is clarified and the extent of revisions is assessed, LLL revised dose assessments are on "hold." Perhaps more important is the possibility that island certification documents may have to be revised and that island usage reconsidered per the guidelines for TRU levels, Roger Ray's only communication on this subject is enclosed (Enclosure G). A team has gone out to Enewetak to make additional measurements for calibration. 6. . With LLL in the process of writing a "final" dose assessment, any comments, suggestions, criticisms, etc., which you may have should be transmitted to Dr. Robison as soon as possible. 7. The Corps of Engineers asked DNA what plans were made for continuing monitoring of the structural integrity of the crypt. -DNA replied that they end their involvement on April 15, 1980, and that DOE will monitor lagoon water, fish, etc. Presumably the direct question was not answered, although I have not seen DNA‘'s response. 8. Except for a request for additional copies of the book "Enewetak Today," we have not heard from Mr. Mitchell since the meeting with the Enewetak people. He is, however, attempting to rally Congressional support for resettlement of Enjebi. 9. It is reasonable to assume that Congressional hearings may be held on this subject sometime within the next few months. 10. DOI recently requested the number of years before exposure on Enjebi would be within U.S. exposure limits. Their letter and a draft of our reply are enclosed (Enclosures H and I), the latter addressing several other issues as well. Any comments would be appreciated ASAP. 11. Whole body counting of the Enewetak people at Ujelang and at Japtan is scheduled tentatively for January-February, 1980.
