Second; a risk approach was re~iewed using information from ICRP, UNSCE-AR, and the National .Academy of Science BEIR Committee. The results of this latter effort are summarized in Part F which follows. The radiological survey of Enewetak Atoll provides a comprehensive data base needed to deri~~e recommendations relative to the These recommendaradiologically safe return of the Enewetak people. tions are to be based on an evaluation of the significance of all radioacti~ity on the -Atoll in terms of the total exposure to be exand on consideration of those pected in the returning population, -reasonable actions and constraints which, where made, will result in minimum exposures.
