RADIOLOGICAL IMPLICATION FOR RESETTLEMENT OF ENEU ISLAND SUMMARY. Unless imported food is a substantial and continuing part of the diet of the Eneu population for about 20 years, unless access to Bikini Island can effectively be controlled for several years, and | unless access to food from Bikini Island is restricted, it is unlikely that radiation doses to people living on Eneu Island would be in compliance with federal radiation protection guidance. and past practices, however, Based upon previous experience it is doubtful whether imported food will be a significant part of the daily diet. It can also be questioned whether or not access to Bikini Island can be controlled. Therefore, a return to Eneu Island should be delayed for close to 20 years if radiological dose is the only governing factor unless a firm commitment can be made which will guarantee that adequate imported food will be available and used by the people, and that residence can be restricted to Eneu Island. If the Enewetak radiation exposure criteria are to be applied to the Eneu population, it is unlikely that the radiation doses to the people would be in compliance with the criteria for approximately 20 years, even if imported food is available and if mobility is restricted. Under either criteria, a return to Bikini Island would be delayed even longer because of the higher levels of radionuclides in the soil. IfheFederalRadiation Council (FRC) recommended exposure limits of 500 mrem/yr to individuals, 170 mrem/yr to average population groups, and 5000 mrem/30 yrs to the average population of the U.S. 2Enewetak criteria are one-half of the FRC exposure limit for individuals and 80 percent of the FRC 30-year exposure limit.
