Ogle, Mr. Michael Bender, and Or. R. Brill| yt se? Or. Ogle (Environmental Aspects) 1. This informal meeting was opened by Dr. William E. Ogle, Energy Systems, Inc. (formerly associated with the Los Alamos Project) who explained briefly how the radiation dose was computed. He noted that the "direct path” radiation was not very significant but that the "food chain" aspect was the important aspect to be considered. Marine food chain with respect to Enewetak is “clean” and presents no problem. 2. Dr. Ogle limited his comments to "Engebi” Tsland. He commented Lhat the Livermore Report waS a good one-that a fine job had been done, although he noted that over 50 years you might find a 50% uncertainty. 3. Using Engebi Island and the worst example, i.@., taking al] 454 pennle and assuming “famine condition" (i.e., no imported foods) but all food from Engebi or the N.E, islands, after 8 years of living on Engebi, the dose assessment which would be received by the people would be 200-250 miligram per year at the peak. 4. Over a 30-year period, this would result in exposure of 4-7 R. 5. Ogle raised a question as to how uncertain is the 4-7 R estimate. He noted that a year ago the estimate without the benefit of the recent “dose assessment study" was twice as high, i.e., 8-14 R aver a period of 30 years. Standards in USA for a 30-year period would be 5 R. Fed. Summary of Dr. Ogle’s opinion: 1. No problem at al] with respect to return of people of Engebi. 2. If there is concern for "any risk", you could decrease the 4-7 R range by increasing amount of imported food brought in, or by delaying use of consumption of local food, j.e., coconuts for another stated period. 3. He further noted that only 15% of food now consumed (3/10 of a daily 2 pound diet) is Jocally grown in any event. Or. R. Brill(Cancer Risk) 1. Or. Brill described what the dose assessment meant in terms of effecl on the people. He noted that there is 2-3% chance of increase in cancer risk to people exposed to l/rem per year. You cannot tell which might be radiation induced or natural. Also in the U.S. there is a 15% chance of anyone getting cancer.
