Runit where the dome is located, and possible hazards from fission products that may arise if the northern island of Enjebi is resettled. Although this committee's charge was not expressly directed toward hazards associated with the resettlement of Enjebi, it must be emphasized that the risks from the consumption of food grown in the northern islands are high compared with any conceivable risk arising from rupture of the dome. The reader of this report will discover that the committee depended heavily on information furnished by government agencies and their contractors. Insofar as possible it attempted to assess the quality of these data and, in one important instance (the drilling program described in the report), supervised the acquisition of new information about the quality of the deome's construction and the concentrations of “radioactivity contained within it. In its interpretation of potential hazards associated with the dome the committee depended heavily on data acquired by groups at the Lawrence Livermore Laboratories led by V. B. Noshkin and W. L. Robison. Members of the committee reviewed the sampling and analysis procedures used by these groups. In addition, all the work on the Enewetak operation done by these groups has been subjected to critical review by a select panel of experts from other government laboratories and from universities; much of the work also ‘is published in seientific journals and, thus, has been subjected to peer review there. The Committee therefore is satisfied that the. information it has received concerning environmental sampling, analysis, and dose assessment is of high quality. The Committee on Evaluation of Enewetak Radioactivity Containment wishes to acknowledge the cooperation of the many individuals who provided extensive information and assistance. ‘The committee is particularly grateful to Thomas Jeffers, Director for Logistics and Administration, Defense Nuclear Agency, Alexandria, Virginia; Roger Ray, Deputy for Pacific Operation, Nevada Operations Office, Department of Energy, Las Vegas; Bryon L. Ristvet, Test Directorate, Pield Command, DNA, Kirtland Air Porce Base, New Mexico; William Robison, Section Leader, Terrestrial and Atmospheric Sciences, Environment Sciences Division, Lawrence Livermore Laboratory, Livermore, California; victor Noshkin, Marine Sciences, Environmental Sciences Division, Lawrence Livermore Laboratory, Livermore, California; and David Stark, Concrete Materials Researcha Department, Portland Cement Association, Skokie, Illinois.
