Because of ‘the 18 people on Ailinginae (reported to be unpopulated), confirmation of the status of other atolls involved in significant fallout was obtained from the Trust Territory representative at Kwajalein. Of particular interest were Bikar and Taka for BRAVO fallout and Taongi for future shots. These atolls proved to be unpopulated as reported; the peo- ple on Ailinginae were not permanent residents, but only temporarily at Ailinginae to fish. The offsite fallout findings, summarized by a member of the CTG 7.1 Advisory Group, are presented in Table 22. PATAPSCO CONTAMINATION The Patapsco, a gasoline tanker, was moored at Enewetak to unload aviation gasoline 2 days prior to the BRAVO detonation. The ship was ordered to leave and proceed at full speed from Enewetak to Pearl Harbor because it lacked adequate radiation equipment and protection gear. The ship's speed was reduced to one-third full speed on 28 February, however, because of a cracked cylinder liner. The ship was about 180 to 195 nmi (333 to 361 km) east of Bikini when BRAVO was detonated. The ship had been vectored approximately along the BRAVO cloud hot line by the transient shipping search aircraft on D-day afternoon. In the early to mid-afternoon of the following day (H+31 to H+32.5), at a range of about 565 to 586 nmi receive fallout. known. (290 nmi (1,051 to 1,084 km) from ground zero, it began to The intensity of the fallout radiation is not accurately Flight Able reported that a little later in the afternoon Bikar 537 km east of Bikini) was reading about 0.600 R/hr. Estimates made by analysts working with the rates measured when the ship arrived at Pearl Harbor range from as high as 0.620 R/hr (Reference 85) to 0.183 R/hr (Reference 86). No steps to decontaminate the ship were taken en route to Pearl Harbor because it appeared to those on board that the level of radiation was too low to cause concern. The ship arrived at Pearl Harbor on 7 March and was 230
