Little y CDR wr FFU’ AUG 11 1972 During the period Julv 26, 1972, to August 2, 1972, a joint AEC-DOD team visited Eniwetok Atoii to conduct a survey of those portions of Runit Island which are to be used for a PACE cratering experiment. A thorough radiolosicel survey was made of that portion of the island which will be disturbed by this experinent. Soil samples were taken in the exnected crater area. Jn addition, a survey for plutonium particles was made along the access road and 22 locations were identified as potential sites for plutonium debris. We lsaon he results of this survey will be used io determine the precautions required for conducting the PACH experiment as planned, or the necessity for relocating the experiment scheduled for Runit Island. Along the ovean recf of Runit there is a very large quantity of scrap metal debris covered with water to various depths depending cn the tide. This debris resulted from the tests on Runit. Some of it was blown onto the reef by these tests. Some was pushed onto the reef during cleanup orerations in preparation for ether tests. Much of the debris is metal scrap romainine from the complex diagnostic experiments conducted during the LACROSSE event, which was a surface burst. A spot check of one pile indicated that the debris is contaminated to levels that would require removal in a subsequent cleanup operation. Experience with similar scrap at Bitini suggests that materials blown onto the reef will also be contaminated. It is expected that the quarantine on Runit will remain in effect urtil AEC and DOD have reached agreement on the plans and precautions that are needed. The PACK staff is drafting a report, for AEC consideration, of the survey and remedial actions necessary to continue the PACE experiment on Runit. ,
