Joe-Deal | he: JAN 2 2 1975 AEC had reviewed plans for building the Bikini houses with ' the idea of commenting on those things that would keep radiation exposures down. Among these was use of clean sand and aggregate for making concrete, addition of soil cement floors under porches, and covering ground around houses with coral gravel. Dr. Biles stated that the study of Enewetak Atoll had developed new findings with regard to terrestrial foods that are probably applicable to Bikini Atoll as well. The possible construction of additional houses on Bikini Island was discussed. I reviewed Gustefson's predicted doses for a village on Bikini where it was assumed that children would spend 10 percent of their time in the interior. See Attachments Vill and IX. For comparison I snowed preliminary estimates of LLL predictions using updated monitoring resuits end dose models that were used to make the Enewetak estimates. See Attachments X and XI. I reported that these new preliminary estimates are disturbing, the problem being the component of total dose that may come through use of locally grown foods. I stated that additional restrictions on use of locaily grown food such as pandanus mzy be needed when those crops start to become available {in the next few years). 1 , , I pointed out that those living in any new houses built iu the interior of the island would receive higher exposures than for the present village location. I stated that it was the total dose that is important, and that our goal is to keep that dose to a value as low as practicable and as low as for those living on Enewetak. Mr. DeBrum wanted to know if it was safe for the people already living on Bikini Island to remain. The answer given was that the exposures to external radiation for people living in houses along the lagoon road was expected to be acceptably low and that no significant amount of local terrestrial food is yet available. The current diet consists primarily of fish, which have very low levels of radioactivity, plus imported foods. _ It was stated, however, thet additional evaluation of radiation exposures would be needed if more houses are constructed on Bikini Island in the interior of the island where levels of external radiation are known to be higher. These calculations and evaluations would take about three monthsof effort. DOE ARCHIVES Harry Brown stated that there is need to establish a Bikini Advisory Group, BAG, (my euphemism) to coordinate activities of Bikini rehabilitation. A member should be identified from each of the several agencies that are involved. The following
