General Manager AEC-DOD SURVEY AT ENIWETOK ATOLL During the period July 26, 1972, to August 2, 1972, a joint AEC-DOD tean visited Eniweteok Atoll to conduct a survey of those portions of Runit Yaland which are to be used for a PACE cratering experiment. A thorough radiological survey was made of that portion of the island which will be disturbed by this experiment. Soil samples were taken in the expected erater area. In addition, a survey for plutonium particles waa made aleng the access road and 22 locations were identified as potential sites for plutonium debris. The resulte of this survey will be used to determine the precautions required for conducting the PACE experiment as planned, or the nacesaity for relocating the experiment echaduled for Runit Island. Along the ocean reef of Runit there ia a very large quantity of scrap metal debris covered with water to various depths depending on the tide. This debris resulted from the tasts on Runit. Some of it was blown onto the reef by these testa. Some was pushed onto the reef during cleanup operations in preparation for other tests. Much of the debris is metal ecrap remaining from the complex diagnostic experiments conducted during the LACROSSE event, which was a surface burst. A spot check of one pile indicated that the dabris ia contaminated to levels that would require removal in a subsaquent cleanup operation. Fsperience with similar scrap at Bikini suggests that materiale blow onto the reef will also be contaminated. It 4s expected that the cuarantine on Runit will remain in effect until &8C and DOD have reached agreament on the plane and precautions that are needed. The PACE staff te drafting a report, for ARC consideration, of the survey and rencdial actions necessary to continue the PACh experinent an Runit. BEST COPY AVAILABLE OFFICE p SURNAME p> |...
