J ler €° Premise: The Government of the Marshall Islands resolves that the People of Enewetak may not resettle Enewetak Atoll because of unacceptable risks from radioactivity. Response: The Enewetak Cleanup has been accomplished to a degree which will allow for safe habitation of the atoll within the restrictions specified by the United-States in the Environmental Impact Statement on Cleanup, Rehabilitation and Resettlement of Enewetak Atoll (EIS) and accepted by the People of Emewetak prior to the beginning of the Cleanup. The resettlement of Enewetak Atoll is to be restricted to the extent that expected dose to people from radiation will be limited to low levels. The restrictions om resettlement require: (1) dwellings only on southern islands of the atoEl1; (2) no deliberate cultivation of food on any northern island except for coconuts on ten specific northern islands; (3) no consumption of coconut crabs or use of well water from any northern island; and, (4) no visits to quarantined northern island (Runit). Thus, the lifestyle to be followed by resettlers is predominantly Oriented toward the southern islands where radioactivity is least abundant. The restricted lifestyie is not without some increase in radiation dosc and risk or adverse health effect; however, the risk is considered to be very small. Every person, inelmding the people of Enewetak, receive some radiation dose due to natural radiation, and this would have applied at Enewetak even if there had been no nuclear weapons testing program. The US National Council on xadiation Protection and Measurements (NCRP) has estimatod "natural" dose equivalent rates to the average man in the US as follows: 6.055 rem per year to the whole body from exposure to natural radiation external to the body, and 0.115 rem per year to bone from exposure to natural radioactivty in the body as well as radiation external to the body. These "natural'' dose equivalent rates are also reasonable estimates of dose from natural radiation at Enewetak Atoll. As presented in the EIS, the man-made radioactivity throughout the atoll - hac FS ee aert is predicted to cause peak dose equivalent rates to the average resettler of about 0.020 rem per year to the whole body and 0.185 rem per year to bone. These peak rates will occur several years after resettlement and will continuously diminish in subsequent years. About 40 percent of each estinated rate is attributed to the consumption of coconuts grown on the northern islands. However, a recent reevaluation of the Enewetak diet indicates that coconut consumption is considerably less than previously assumed. Accordingly, the dose rates above may be overestimated. Thus the cumulative dose to average persons following the planned lifestyle for Enewetak from natural and man-made radioactivity will be within about a factor of three of the dose they, or average persons in the US, would receive froz nature alone. The NCRP recommends the dose equivalent rate to whole body for the population (US) us a whole from all sources of radiation other than natural radiation anc radiation from the healing arts shall not exceed SCOS12g 6
