-3- The possible marketing of copra produced on the atoll needs to be evaluated in an "As Low as Practicable" context prior to decision making in order to determine if the economic benefits to the Enewetakese outweigh the radiological cost of the population dose delivered to off-island populations. The total quantity of plutonium and strontium radionuclides estimated to be present in lagoon sediments are somewhat greater than are present on the islands of the atoll. Apparently, the majority of the contamination is in the northwest portion of the lagoon. The Draft EIS does not discuss the short and long range implications of this source, nor does it indicate whether any consideration was given to the feasibility of minimizing the future radiation dose that will be obtained from the seafood pathway. There is no discussion of the decision to permit fishing in all of the lagoon. Apparently, this recommendation came from the conclusion on page II-43 that there was "no statis- tically significant difference for dose estimation purposes between samples taken in @gifferent parts of the lagoon." The data depicted in Figures 160-161 suggests that 137Cs, 90Sr, 239Pu concentrations in convict sturgeon may be somewhat higher near Belle and Irene, where bottom sediment concentrations are also highest. The recommendation to ban coconut crab collection in the Northern Islands is perhaps prudent but was reached without actually sampling any crabs in that part of the atoll. Also, the possibility of this restriction being observed is uncertain because it is a delicacy, in short supply, and the islands. would be open for picnicing and fishing. Clean-Up Operation We have no specific comments to make about this phase except to note that there will be significant possibilities for inhalation exposures to workers and transport of radioactive material from greater to lesser contaminated portions of the atoll. Constant health physics support will be needed.
