DRAFT 9 roentgens in 58 hours; 154 Utirik residents, 17 roentgens in 78 hours; and 401 Ailuk inhabitants, not evacuated, less than 20 roentgenstotal doses for their lifetimes.” An Armed Forces Institute of Pathology study estimates point source doses at "260 r." for the Rongelapese and "20 r." for the Utirik group.” Later studies by the AEC/DBM estimate that some Rongelapese may have received a whole-body gamma dose of 175 roentgens; that 20 percent incurred deep lesions; 70 percent, superficial lesions; and 10 percent, no lesions; and that 55 percent lost some hair, which regrew later.* According to later estimates, the thyroid glands of young Marshallese children absorb approximately eleven microauries of iodine’®’ and from 700 to 1400 rads.* 2 Mar 54 RADIATION After the task force radsafe officer measures 0.200 R/hr at 500 feet in a morning flyover at Rongerik, the radsafe officer evacuates 28 U.S. weather personnel from that atoll. An afternoon flight over the populated Marshalls extrapolates, 1.350 R/hr at ground level at Rongelap; 0.400 R/hr at Ailinginae, 0.001 R/hr at Wotho, 0.240 R/hr at Utirik, and 0.076 R/hr at Ailuk. The flight over the unpopulated atolls calculates ground contamination as 0.600 R/hr at Bikar Island and Taongi Island at 0.014 R/hr. Task force officials then decide to evacuate Rongelap, Ailinginae, and Utirik Islands. They send the destroyer USS Philip 43 nautical miles southwest of Eneu Island, to evacuate Rongelap andAilinginae the following morning and the USS Renshaw, 13 nautical miles north of Eneu Island, to evacuate Utirik on 4 March. Meanwhile radsafe monitors flown to Rongelap measure 1.400 R/hr in the living quarters of Rongelap Island.*’ 3 Mar 54 RADIATION RELOCATION The U.S. Navy DDE Philip evacuates 64 inhabitants from Rongelap and eighteen Rongelapese from Ailinginae and takes them to Kwajalein.” JTF-7 radsafe monitors measure 0.160 R/hr on the ground at Utirik !sland.” 4 Mar 54 MEDICAL RADIATION. * RELOCATION: mo os The DDE Renshaw evacuates 154 Utirik inhabitants to Kwajalein. The JTF-7 reports “comparatively low radiological exposure of this group." Medical examinations at Kwajalein of the Utirik people reveal no sickness butfind a loss of appetite among some small children, a condition physicians attribute to diet change.” 5 Mar 54 AGREEMENT CONTRACTOR MEDICAL RADIATION RELOCATION Gen.
