The likelihood of an individual receiving a dangerous dose of radiation from external radiation on either atoll is extremely small because “ of the low average of surface radioactivity levels. The lagoon water has very low radioactivity levels, the fish and shell fish were found to have low levels of radioactivity also. However, the foods which are grown in the soil containing cesium and strontium were found to have high levels of activity and were predicted to be the principal sources of exposure. In some cases the”ground water contains cesium and strontium. Differences “ The differences are significant. At Enewetak there were 43 tests, one of which was a safety test which produced no nuclear yield but a large amount of contamination, compared to only 23 detonations on Bikini. All of the tests at Bikini were over water placing the craters and most of the debris in the lagoon. At Enewetak the majority of tests were conducted on or over land. All but two of the tests were on the northern islands where a“llthe significant radiological contamination is found. On Bikini the contamination is principally the result of fallout while at Enewetak induced radiation as well as fallout contributed to the contamination. During testing Enewetak had well-established base camps to southern support scientific and other test personnel in ttce half of the atoll which is relatively free of contamination whereas all of the islands on Bikini Atoll were contaminated to a degree, some more than others, by fallout. Scope of review We reviewed the Enewetak Atoll cleanup, rehabilitation, and resettlement project to identify significant issues which should he resolved before. . the United States considers the project finished. Me interviewed officials of “agencies involved in the project and representatives Qf the people of En&etak. Me also reviewed pertinent files, reports, and other materials and observed conditions on the atoll. The review was principally performed at --DNA headquarters, Arlington, Virginia; ● --DOE headquarters, Germantown, ”Maryland;. --DO~ headquarters, Washington, D.C.;- . 7“
