Diet. We. have also attempted through the assistance of the Peace Corps to find out quantitatively what infants and small children eat. (Such information will be of value to the professional nutritionists in the Marshall Islands as well as to ourselves.) The Corps volunteers, all of whom speak Marshallese, carried out inquiries on their own islands of residence where they are familiar with the local scene and people, and have lived for at least one year. The diets were ascertained by living with a family for one day on two separate occasions and recording what was eaten by the child (Note 13). At present we have only the returns from 5 islands c: comprising 21 children, 7 months to 4 years of age (but ch: -‘ atolls, ly below 1 year). The principal finding, as might have been expect..:, is that children are breast fed until well past 6 months of age, in fact often into the first year. A second important finding appears to be that additional foods during the weaning period a: often, if not usually, imported. The diet, however, varies greatly from family to family, as well as from day to day {to judge by these two-day samplings). I have used Table 4.2 #2 and related material in calculating the daily intake of cesium-137, from the individual diet reports. The two reports for each child were averaged, and then an average obtained for the island. In the summary below, the island mean is followed by the range, followed by the number of children, in parentheses. 1. 2. 3. 4. 5. Ine Island, Arno: Buoz Island, Ailinglaplap: Kaven Island, Maloelap: Woja Island, Ailinglaplap: Wotje Island, Wotje: The maximum samples was probably an cesium-137, 128 113 212 405 500 pCi/d pci/d pci/d pci/d pcCi/d (0-210; 3) (0-215; 5) (58-343; 3) ( 7-995; 9) (215-785; 2) individual daily intake of cesium-137 indicated by these not a constant one, but may be used to estimate what is upper bound for daily consumption. For 1000 pCi/d of the dose would be (1990): (1000) x (1.1 x 1.7 x 10-5) = .019 rem (committed first year dose) Scaled to 1978, it would be .025 rem. The strontium-90 dose would be less than 5% of this. It is not claimed that these results are definitive. Nontheless, I believe that these data do provide at the very least significant orientation to the problem. Accurate data are very hard to obtain, according to the volunteers, and the investment in time -- about 2 days per child -- has been a very large one, indeed. One difficulty encountered was getting the mothers to understand what kind of information was wanted and why. No brief interrogatory visits could obtain reliable data. The study is still going on, and it is hoped that more information will be available by October. 38
