Eniwetok, and this Group has been involved since the inception of the study in the development of a measurement and evaluation plan which optimizes the return of information aimed at the objectives. The design of the program has been formulated after considering the following requirements: , 1. Program focus. That the program plan be developed in response to a well-defined charter and objectives, as stated and discussed in the first section of this report. 2. Use of existing data. That past studies and data be brought to bear on the measurement and evaluation program design, including survey data from Eniwetok and Bikini and the more general literature on radioactivity in food chains in the Atoll. Such data have provided guidance for developing measurement plans which will give comprehensive information for assessing radiological aspects of future habitability and the feasibility of clean-up prior to rehabilitation. 3. Integrated program structure. That information and materials flow through a system of sample collection, identification, analysis, and interpretation which provides for the best utilization of time and resources, minimizes errors and losses, and allows for rapid feedback and long term access to samples, raw data, and logic sequences which lead to results and interpretations. h. Technical resources for evaluation. . That the evaluation of data for radiological assessment be approached in a way which utilizes the very latest understanding of radioactive transport in the environment and of mechanisms and parameters affecting the dose to man, This principle is to be implemented by drawing on resources and capabilities in a number of institutions, including LLL, LASL, HASL, and the University of Washington. In addition, information on projected living patterns of future inhabitants which might influence a radiological assessment will be evaluated with the assistance of experienced in- dividuals. Contact is being made with Dr. John Tobin, an anthropolo- gist very familiar with the living habits of the native population, in this matter, and we will also draw on scientific investigators of long experience in the Atoll, such as Dr.'s Held and Seymour of the University of Washington, Additional key participants and consultant -6. :
