Dr. Robert Conard Qe DEC 14 1973 times Gustafson's predictions even with no Pandanus in the diet if Arrowroot and Crab are left in (these are now available) and if the diet is deficient in calcium (i.e., 0.42 gm/day). The next part of Enclosure | gives a brief report on the trip to Kili in 1968 to talk with the Bikini people and their Council and to answer their questions. Also, inthis section are the Q's and A's developed for the 1970 field trip. A limited number of copies of this were given to Trust Territory officials we met during the trip. The last section of Enclosure 1 presents some information on radioactivity in Copra and the ultimate destination for copra products. Enclosure 2 is a trip report written following the 1970 Bikini survey. It contains a record of daily activities and some of the problems one typically faces in carrying out sucha survey. You will note there was very little contact with the Bikini workers for this visit due to their early departure from theatoll. One word regarding the updating of Gustafson's estimates. Ihave tried to keep Phil informed of what has happened since he left DBER. We have considered the revised estimates in Enclosure 1 as pre- — liminary and unconfirmed and would be more than happy to see anyone else make an independent set of estimates using the same data. Ido feel that considering the findings since the 1967 survey and since the Ad Hoc Committee's recommendations, and considering the increased general concern for radiation exposures, that measures ‘to reduce exposures of Bikini residents, and to keep such exposures as low as feasible, must be considered more than something desirable to do, i.e., an extra or bonus benefit. I would urge that the precautions for Pandanus planting and calcium supplement for the diet be considered firm requirements and priority items in the followup of the Ad Hoc Committee's recommendations. Itis, in my view, most important for someone who knows conditions in the Marshalls to determine the most effective way to introduce the calcium supplement, to pin down who is responsible for conducting and funding this effort, and to make sure that those Trust Territory officials who have to do with agricultural rehabilitation of the atoll know of the importance of the recommendation on planting Pandanus and that they implementit. ae sani peeeyt- Ore OTTTie bs wisian & (O20
