Living Fattern 1, where the home island and agriculture are on southern islands, is the only living rfattern for these two situations where the total bone-marrow doses do not exceed 50% of the FRC guide; in this instance, it is less by a factor of 5. All other living patterns lead to an annual dose which for at least lyr, and in a e most cases several years, exceeds the FRC guide. in part to the assumed diets cf adults and children and the large and 137 A aban aps Onn abnd ae Cs intaxe via the focd chains for hae = Qs Ss oO I “ te n a} ty n Qu O ui om o fF 3 3 m9 5B ty 3 te ct between the predicted child and adul ont The results also indicate that there is not a great deal of difference Sr aa such Lroducts as tandanus, breadfruit, coconut, and meat. children are assumed to have an intake twice that of the adults, but until ase 10 the rest of the dietary intake is assumed to be one-half As a result of this actior, three living patterns fall within 5C% of the FRC 2, and 5. guide — Patterns 1, < and breacfruit are srown cn scuthern islanis only. When pandanus, breadfruit, coccnut, and tacca are all confined to southern islands, then Living Pattern 32 also falls within the suice (Table 4). If the total diet is confined to the southern islands, then all living patterns are within FRC guide, and the oniy variation among living patterns is the result of the difference in external exposure for each of the situations (Table 5). For all the cases where there is a restriction on the agriculture and diet, it is assurei the village islarda will be plowed anda graveled. IV—9
