Although it had not been anticipated that evacuation would be required, plans for such an eventuality had been made - as they should have been in a good safety plan. Both aircraft and surface ships were dispatched to Rongelap and at about H + 51 hours, 16 Rongelapese were evacuated by air and 48 by surface ship. rads.>° Their total whole body exposure was about 175 Although the radiation exposure levels on the Island of Sifo on Ailinginae Atoll were less than one-half those on Rongelap Island, 18 inhabitants of this island were also evacuated by ship at about H + 58 hours. They were all taken to the Island of Kwajalein and given the best medical care, and their needs amply supplied. They were moved to the Island of Ejit on Majuro Atoll in June 1954 and returned to their home islands on June 29, 1957. A full account of the initial medical findings are contained in reference 3. Subsequently, annual medical examinations have been made by Dr. Robert A. Conard and his associates at the Brookhaven National Laboratory and the results of this outstanding work are reported in reference 4, By Late in the evening of the second day after the BRAVO detonation, radiation reports had been received about the Island of Utirik - about 315 statute miles to the east. It was not as apparent that evacuation was essential as it was at Rongelap Island since the radiation levels were considerably less, inhabitants: There were cogent arguments against evacuation DPRARCHIVES (a) the estimated radiation doses probably would not exceed 60 rads - even if they remained on the island for a lifetime (b) evacuation
