Following the accidea ar 1954 the American physicians and sciencis rt -« ansy uv UWOB give full e:xantinations , as they do in Qoncelan. if 0b? cr eeow to the vedole of Utirik every y S involyed, based on knowledge of human radiation efiects available at that time, did not believe that the dose estimated to nave been received by the Utirik people would lead to diseases caused by radiation. Also, since they had shown us acute effects and only a slight statistical depression of platelet cownts, they were returned to theic home island. However, it was considered prudent that the Utirik people should be examined at regular intervals and they were given complete physical exeminations in 1957, 1959, 1963, 1966, 1969, 1972 and 1975. During the past six years special attention has been paid to thyroid examinations on an annual basis and all of the people on the island have been encouraged to be examined and treated by the physicians at sick call. Since 1973 the resident physician has visited Utirik on a quarterly basis. Dr. Kotrady was employed by Brookhaven National Lavoratory to continue and expend the progrem initiated by Brookhaven and | first carried out by Dr. Knudsen. There were different return times for the Utirik people and the Ronclap people from Kwajalein (following their evacuation) in 1954~-~the PEQILE of Utarik returned to their atoll after three months, and the people of Rongelap returned to their atoll after three yearse receive Hore \ Hould it be correct to say that perhaps the Utirilk people ? than only 14 rads in light of their quick return time to Utirik Although the estimated doses received by both Rongelap and Utirik people are inexact, a review of the data indicates that the dose estimates aré reasonable estimates. There were marked early effects in the Rongelap people, but the lack of acute symptoms and the minimal blood changes detectable by statistical means in Utirik individuals is consistent with a small dose. ‘The fact that the litirik people were returmed to their home island several months after the fallout would have contributed only a very slight increase in dose since surveys of the island revealed that the radi - tion levels were very low.
