be ERongelap Sixty-five natives were evacuated to Kwajalein and aay have received doses as high as 130 roentgens in a period of 51 hours. In this case, the level of radiation is about the leval which might cause sone syaptoms such as nausea, vomiting, fatiguability and less of hair for acute doses. Allowing for the reduced effect from low dose rate it zay happen that symptoms as above will occur in individuals who were already ill or is generally poor physical condition. Readings of skin and hair contamination were such that for this exposure time spotty distribution of beta burns could occur within several days. If this occurs, ulcerations might develop which may require several months to heal. ce. Aijinginae = Seventeen natives on this island were exposed to approriaately 80 roentgens in 58 hours. They were evacuated to Kwajalein. It was not expected that any subjective systemic symptoms wuld develop. However, personal contamination of this duration could conceivably cause beta burns in a spotty distribution with ulceration as described above. a, Gbirtk 154 natives were evacuated to Kwajalein after receiving a dese of 17 roentgens in 78 hours. No subjective systexic symptoms or wor . changes in blood count were expected. possible statistically. Beta burns are unlikely but are e. Ailuk with 401 natives was not evacuated and the total dose for a life time will be less than 20 roentgens. No medical problem froa radiation should occar in the population. 2. Some other islands received fall-out exposing inhabitants te insignificant quantities of radiation. g- ‘Task Force personnel at or in the vicinity of Bikini Atoll - Personnel in the concrete bunker on NAN island were evacuated to ships afloat receiving in general comparable dosage to those aboard shines all the time. Based on readings taken aboard the ships it was estizated *het none of the ship's pereonnel would receive more than 10 roentgens whole body radiation. This dose would not cause any general syz=ptoms of radiation sickness, however, decontamination personnel aight have skin contact with concentrated radicactive deposits and possibly sustain cild beta burns. 6 All native evacuees were held at Kwajalein for observation ant com treatment should the need arise. ‘he station medical coxzplement took Captain es. histori took and tions exarina l poysica plete blood counts, zace B, H.
