The radiological survey of Enewetak Atoll provides a comprehensive data base needed to derive recommendations relative to the radiologically safe return of the Enewetak people. These recommendations are to be based on an evaluation of the significance of all radioactivity on the Atoll in ‘terms of the total exposure to be expected in the returning population, and on consideration of those reasonable actions and constraints which, where made, will result in mininum exposures. The guidelines used in deriving these recormendations can be summarized as two interdependent considerations: l. Expected exposures should be minimized and should fall in a range consistent with guidance put forward by the Federal Radiation Council (FRC) . 2. | Actions taken to reduce exposures should be those which show promise of significant exposure reduction when weished against total expected exposures and the "costs" of the actions. "Costs," in this context, are measured primarily in terms of costs to the Enewetak people as constraints on their activities or as dollar costs for cleanup or remedial action. ~41-09
