RG 326 US ATOMIC EXERGY COMMISSION \~ et ad i To establish the earliest possible date of safe return of the natives to Rongelaap and Ailinginae Atolls, and secondarily to gain information of considerable value to the problems of Operations Gabriel and Angel. B. Areas of Study 410607 1. The home island - Rongelaap. 2. The remsining islands in Rongelaap Atoll. 3. Nearby contaminated atolls such as Ailinginae which are visited by the natives for fishing, etc. C. Systems Within the Environment for Study 1. General contamination as deduced by gamma ray surveys. (a) Indicates external gamma background. (b) Indicates regions of varying uptake into plants. {c) Indicates something of the reservoir from which activity may be concentrated by biological systems, 2. Sources of internal contamination. (a) Water supplies. (b) Terrestrial foodstuffs. (c) Marine foodstuffs. - (d) D. Airborne dusts as indicated by standard dust sampling procedures. Temporal] Sequence of Study - for prediction purposes the time rate of change of the contaminating factors is fully as important as the absolute levels found. 1.
