2. He also used the "worst" situation, i.e., taking al) of the Enewetak population (454), assuming that they would al] live on Engebi, would eat local foods under "famine" conditions. Under this situation, dose would be 360 r/yr. This would result in .84 cases of radiation cancer above the 68 natural ones expected during this 30pm period. For a small group, then, the risk is 0-1, f.e., only 1 more cancer than would normally be expected would occur and you couldn't “pick” this case out. 3. in essence, "risk would be zero". Dr. Brill commented that the greatest hazard js that increased medical attention which will identify more cancer cases. But there would be no way to tell whether any of these were radiation induced. He noted that radiation is a low factor of risk. As an example, he cited that a “smoker” subtracts 225 days from life whereas radiation at the Engebi Jevel would subtract only 16 days. Or. M, Bender (Genetic Effects) 1. He pointed out that cancer and genetic effects are the only ones known to occur from Jevels of radiation as found at Engebi. Ww Studies at Hiroshima produced no hard evidence of genetic effects in man. For "Engebi" he maximized the risk... took a presumed 7.5 dose (i.e., constant famine situation, etc., and assumed 7.5 R exposure to each child). Since there would be a 10-11% chance, in any event, that a child would be born with some abnormality, the additional exposure risk at Engeb? would add onty .0004 to .0006 added risk, Jess than one-half of a percent. This would be a very smail risk. Could expect 1 rad/year. 1} extra abnormality in each of 3 generations exposed to In short, if all the Enewetak population were to live on Engebi, under the worst conditions, radiation would induce “one” additional defect every 83 years. These would not be “monsters” but variety of "defects". Dr. Bender also stressed that the Federal Radiation Guides are "guides" only, not mandatory rules for people to follow. He noted that people in Denver receive higher annual exposures than would the people at Engebi. He stressed the exaggerated "fear" of radiation risk and stated that in his opinion there had been too much explanation and warning about hazards of radiation given ta the people of the Marshalls and this has blown the situation out of proportion.
