Weisgall Ginsburg, Feldman, Weil and Bress 1700 Pennsylvania Avenue, N.W. Washington, D.C. 20006 Dear Mr. Weisgall: Mr. Hollister requested that I respond to your letters of October 16, 1980, and of November 3, 1980. Please excuse the unusual delay in responding. As you know, the information we presented at Kili Island in the book, ''The Meaning of Radiation at Bikini Atoll," indicated that the people could return to Eneu Island with the expectation that the resulting radiation doses would be within the United States Federal standards if (a) residence was restricted to Eneu Island, (b) at least 50% of their diet would consist of food from outside the atoll (imported food), (c) that time spent on Bikini Island would be controlled and minimized (10%), and (d) that no food from Bikini Island would be eaten. (Since these estimates were based upon the averaged values of a number of parameters, the indi- vidual with unusual personal habits and lifestyles may vary -- in either direction -- from these estimates.) It also was stated at Kili that without imported food it would be about 20-25 years before the people could return with the expectation of living within United States radiation exposure limits. This information is consistent with the information provided by the Department of Energy (DOE) to the Department of the Interior (DOI) ina letter dated May 15, 1979, from Ruth C. Clusen, Department of Energy Assistant Secretary for Environment, to Mr. James Joseph, Under Secretary of the Department of the Interior. paragraph: That letter contains the following "If the guidance of the Federal Radiation Council (FRC) (S00 mrem/yr to individuals, and 170 mrem/yr and S000 mrem/ 30 yrs to a population) is to be complied with, the people could return to Eneu only if it is assured that adequate imported food would be available to and used by the people for approximately 20 years, that food grown on Bikini Island is not a part of the diet, that residence is restricted to Eneu Island, and that visitation to Bikini Island is effectively controlled."
