36 bulldozing.” On Runit there is plutonium well below the surfa which would be difficult to remove without scraping off the so to bedrock. The seriousness of the quarantine has been made v to the people of Enewet2 and they so far have respected it. mittee strongly endorses their determination to retain the qua of the entire island of Funit. | 6.2 Enjebi Island As explained in the Preface, the principal mission of the ttee is to "assess the effectiveness of the Cactus Crater structure In preventing harmful amounts of radioactivity from becoming availablB for internal or external human exposure.” In addition, the committ¢e also was instructed that its assessment of the Cactus Crater structuje wes to be “set against an understanding of the expected living pattdrns of the people of Enewetak in terms of their degree of contact withjRunit Island and their exposure otherwise to residual radioactivity on the atoll." Cons-quently, the committee believes it must comment ¢« radioactivity hazard on Enjebi since it probably is inevitable that the Dri-Enjebi will return tc that island to live and grcw at least of their food. 6.2.1 Radioactivity on Enjebi The soil removed contained about 5 Ci of transuranics. However,] there are only localized areas (about 3 percent) that do not satisfy transuranic habitation standard of 40 pCi/g soil (U.S. Departme Energy 1980). Thus, transuranics are not a problem on Enjebi. toward the fission products, especially °*Sr and '*’Cs. they were leached out of the top several inches of concentrated at depths not feasible for excision. products are particularly troublesome because they crops, especially coconuts, and, hence, are easily As mentioned topsoil and These fission concentrate i ingested. 6.2.2 Dose Assessments An extensive dose assessment study utilizing data collected Bikini and Enewetak Atolls over a period of many years has been "An exception may be Lujor, near Enjebi, where it has been s ‘letter from W. J. Bair, Chairman, U.S. Department of Energy Ene Northwest Laboratories, Richland, Washington, April 28, 1978) tha soil profile on Pearl [code name for Lujor] is anomalous since th concentration of transuranics appears to be uniform with depth.” final island certification survey after the cleanup, however, re that Lujor meets the criterion for an agricultural island and tha there are no known or suspected radiological burial sites.
