be Rongelap Sixty-five natives were evacuated to Kwajalein and may bave received doses as high as 130 roentgens in a period of Sl hours. case, the level of radiation is about the level which might cause In thls sose symptoms such as nausea, vomiting, fatiguability and loss of hair for acute doses. Allowing for the reduced effect fram low dose rate it may happen that symptoms as above will occur in individuals who were alread y 11] or is generally poor physical condition. Readings of akin and hair contam inatiog were such that for this exposure tine spotty distribution of beta burns could occur within several days. If this occurs, ulcerations might develo p which may require several months to heal. ce. Allinginae Seventeen natives on this island were exposed to approximately 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. d. Shirtk - 154 natives were evacuated to Kwajalein after receiving a dese of 17 roentgens in 78 hours. Ho subjective systexic symptoms or or changes in blood count were expected. possible statistically. e. Beta burns are miikely but are Ailuk with 401 natives was not evacuated and the total dose for a life time will be less than 20 roentgens. radiation should occur in the population. No medical problem fros f. Some other islands received fall-out exposing inhabitants te insignificant quantities of radiation. B- Task Force personnel at or in the vicinity of Bikini Atoll Personnel in the concrete bunker on NAN island were evacuated to shins afloat receiving in general comparable dosage to those aboard ships all the time. Based on readings taken aboard the ships it was estizated thet none of the ship's pereonnel would receive more than 10 roentgens whole body radiation. This doee would not cause any general sy=ptoas of radiation sickness, however, decontamination personnel might have skin con- tact with concentrated radicactive deposits and possibly sustain ciid beta burns. 6. All native evacuees were held at Kwajalein for observation and treatment should the need arise. The station medical complement took com plete blood counts, mace physical exarinations and took histordes. Captain B,. H. Haight, (MC), USN, a radiolegical medical officer was sent to Xwala- Yein as cansultact cn radiation effects to the station surgeon. Daily cb= servation was instituted in anticipation of the arrival of a medical group fron the U. S. who were to investigate the patiexts. a
