ved Also, there were definite changes in levels of blood constituents for months afterwards. The Marshallese have been examined by a team of physicians yearly and to the present time no statistical differences have appeared between them and the “control” group for such factors as birth and death rates, life-shortening, leukemia, cataracts or cardiovascular, arthritic, ophthalmic, or dental defects. pei jrea There may be a suggestion of greater incidence of miscarriages and stillbirths more recent data indicate that and/there may be a lag in growth and development of the children, but the paucity of vital statistics and the small number of persons involved preclude a determination. unc It was reported by the Japanese that some fishermen aboard a vessel near by Pacific Proving Ground on the same date may have received a higher exposure than the Marshallese’-. September 23, 1954 from hepatitis. One of these fishermen died on (Hepititis is a condition not directly attributable to radiation.) The next highest whole body exposures occurred near the Nevada Test Site. The highest estimated exposure to any individual was 13-1/2 roentgens and the next highest 10-1/2 roentgens. The highest estimated exposure to any community was about 6 roentgens. There were about 30. persons who received exposures between 6 and 10-1/2 roentgens. All of the above radiation doses are accumulated doses since the Nevada Test Site opened in 19518-, Having delineated the highest exposures (discussed above) it is proper to discuss "average" exposures since these have relevance for
