5.4.2 Population Distribution Another means of controlling the dose accumulated by the Enewetak population would be to limit the time which t#y spend in the vicinity of radiation sources, principally.by postponing the use of some islands for residence. By limiting the islands available for residence, the population will receive less dose from external sources than they otherwise would. Also, the chance of ingesting food containing higher levels of radioactivity would be decreased. 5.4.2.1 Possible Distributions. which have been considered are: @ The possible population distributions Allof the people of Enewetak would be free to choose their place of residence on any island of the atoll. e The people would be limited to residence on the south islands, Jinedrol clockwise through Kidrenen, (Alvin through Keith). @ The people would be limited to the same group asin 2. above (Alvin through Keith), plus Enjebi (Janet) in the north. 5.4.2.2 The Problem of Enjebi. Because the only difference between 2 and 3 above involves the island of Enjebi, the reason for making this distinction must be justified. Earlier-in Section 3, it was explained that the people of Enewetak were historically divided into driEnewetak and driEnjebi, the first named occupying the largest island in the south, and the other the largest in the north. This traditional pattern was disrupted by the invasion of the atoll by U.S. troops in World War II and has never been fully restored. Restoration of the traditional pattern would require that the people of Enjebi reside on that island once again. However, since Enjebi was ground zero for, or within the fireball of, a number of nuclear explosions, the residual radioactivity of this soil is high enough ‘to produce a sizeable external dose. In addition, all vegetation grown on the island would contain radioactive elements which would 4 increase the internal dosage. The facts have,beenweighed against the strong desire of the driEnjebi to return to their ancestral island. _ oo. 5.4.3 Cleanup and Disposal Colltchr ic The simplest method in concept, of limiting radiological hazards is that of : and disposing of all radioactive materials. Further, a fundamental requirement in any cleanup and disposal is that radioactive materials are to be removed and disposed of in such fashion that they do not become further hazards in another time and place. 5-11 x
