ert . wwe i hknelre Most of the 28 U. S. Service personnel stationed on Eniwetak Island, Rongerik Atoll, received about 40-50 roentgens, based on film badge readings. Three members of the group who were located for part of the time in another section of the island were estimated to have received somewhat higher doses. Seventeen of the 28 personnel showed only slight superfi-~ cial lesions with one questionable case of epilation. It should be pointed out that the personnel were in metal buildings during some of the fallout time and for most of the time thereafter until evacuation. This reduced the direct contemination as well as the whole-pody cumma dose. A film badge hanging on the center pole of a tent at one end of the island read 98 roentgens. Calculations based on dose rate readings at another part of the island indicated somewhat lower doses, if rerson= nel had remained in the open for the period of time from fallout (about H # 7.5 hours) to evacuation (at about H # 34 hours). Upon arrival at Kwajalcin one personnel gemma dose rate reading was as high as 250 mr/hr at about H x 35 hours. The above data do suggest that there muy be possible a rough bracketing of gamma-beta doses versus beta burns. On the one hand, the natives from Utirik received an estimated whole-body gamma dose of 15 roentgens and showed no evidence of beta burns. On the other hand, the natives on Sifo Island, Ailinginae Atoll, received about an estimated whole-body gamma dose of 75 roentgens with 14 personnel showing slight burns, 2, moderate burns, 2, no burns, 3 with moderate epilation, and 15 with no epilation. In addition, Roneglap natives received 170 roentgens whole=body gamma dose, and about 90% showed some degree of lesions and 56%, some degree of epilation.
