RG _ 326 US ATOMIC ENER GY COMMISSION To establish the earliest possible date of safe returnof 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 125302 | of Stud of 1. The home island - Rongelaap. 2. The remaining islands in Rongelaap Atoll. 3. Nearby contaminated atolls such as Ailinginse which are visited by the natives for fishing, etc. C. Systems 1. Within the Environment for Study 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. D. Sources of internal contamination. (a) Water supplies. . (b) Terrestrial foodstuffs. (c) Marine foodstuffs. (a4) 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.
