APPENDIX A ENIWETOK RADIOLOGICAL SURVEY PLAN ~~ : . I. ' 29 September 1972 W.E. Nervik, Technical Director INTRODUCTION Purpose: AEC Headquarters has accepted responsibility for conducting a comprehensive radiological survey of the Eniwetok Atoll. DMA has been given responsibility within Headquarters for the survey and they, in turn, have delegated the responsibility to NVOO. In the wording of the 13 September 1972 implementing directive from DMA to NVOO: ‘"It is the overall AEC purpose to gain a sufficient under- wir pew i - standing of the total radiological environment of Eniwetok Atoll to permit judgments as to whether all or any part of the atoll can safely be reinhabited and, if so, what steps toward cleanup should be taken beforehand and what postrehabilitation constraints must be imposed, It is necessary -, We be Oe to thoroughly examine and evaluate radiological conditions on all islands of the atoll and.in the local marine environment prior to commencement of clean-up activities in order to obtain sufficient radiological intelligence to develop an appropriate cleanup program, Specifically, it is necessary: l- To locate and identify contaminated and activated test ta atta eee ae ‘debris, 2- To locate and evaluate any significant radiological hazards which may complicate cleanup activities, and 3- To identify sources of direct radiation and food chainto-man paths having radiological implications. You are directed to plan; organize, and conduct a radiological field survey to develop sufficient data on the total radiological environment of Eniwetok Atoll to permit the assessments on which the judgments described above can be nbaaig, aie: eerie made. This survey should be accomplished as soon as possible upon completion of the necessary planning and coordination. It should consider the total environment pertinent to rehabilitation including both external radiation dosage ° iy
