24 (No response.) OR. BUGHER: t® I think we all seem to be disposed accept the estimate of 150 roentgens for the average dose for the Rongelap people, with some uncertainty as to that. The uncertainty is not specified, but I should think it might very well be of the order of 25 roentgens up or dow DR. Bugher. SONDHAUS: I should like to add one thing, Dr. In conjunction with considering a figure for the Alderson Reporting Company Washington, D. C. dose under these field conditions, w should bear in mind 10 that this quite possibly needs to be interpreted in terms 11 of the geometry of the exposure. 12 a laboratory experiment is performed m 13 with the dose being divided between both sides of the 14 animals with a bilateral exposure or something of this sort, 15 the depth dose characteristic is quite different than in a 16 uniform 360 degree exposure, such as an individual would 17 receive while standing on an infinite plane. 18 some preliminary estimates of 19 trying to simulate a 360 degree exposure with a cylindical 20 phantom. 21 led to the conclusion that perhaps a 40 per cent increase 22 an animal, perhaps We have begun this at the laboratory by The first figures are rough, but one might be in the dose in terms of a laboratory exposure would result 23 from the same skin dose, but with the radiation from all 24 directions. 25 Same as the entry dose in this case, and the volume dose ARC f Department o Histeria 5 = oe . 3 adge nkaw Tmt is to say, that when 4 Tmt is,the exit dose would certainly be the ,¥ ht a5
