Tis’ PlTSSNtuv rll Vy NAG Ue SIMeuoE su the letter dated January suggest the following: 1. sm mes rw yoo ep ees ee 10, 1979, from Mr. Greenhouse to Tommy McCraw That communication should be improved between Brookhaven National Laboratory and LLL regarding the design, implementation, statistical analysis and dose estimation procedures with regard to radiological surveys of the environs and people inhabiting the Northern Marshall Islands. 2. That an attempt be made to improve the statistical analyses of data in all letter and formal reports to DOE. Even thouch letters may be followed by more comprehensive formal reports it is important that Jetter reports present effective data summaries to provide DOE with timely information upon which decisions may be based. Use of Rongelap Crabs for Food The Advisory Group was asked by staff to review a memorandum on the radiological impact of coconut crabs from the Northern Islands of Rongelap (Greenhouse; BNL - McCraw; DOE 1/10/79). -The Group assumes that the assessmen’ will be the subject of a more formal report since the conclusions given in the verbal presentation appeared to be in conflict with the memorandum. The staff should review the final report and insure that their recommendations are communicated in an effective manner to the Rongelap people. Predictions of Radiation Doses to Present and Returning Residents of the Marshall Islands Because decisions regarding habitation of the Marshall Islands will be based on predictions of radiation doses to present and returning residents, the Advisory Group recommends that all such dose calculations be independently verified by two or more organizations and that the basis for these calculation: be clearly presented. This is not intended to reflect on Livermore activities but we believe DOE cannot risk a repeat of the Bikini experience. error could have major consequences. Singerely yours, W. J.
