The ship was ordered to leave and proceed at full speed from Enewetak to Pearl Harbor b it lacked adequate radiation equipment and protection gear. cause The sifip'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 not line by the transient shipping search aircraft on D-day afternoon.

Esfimates made by analysts working with the rates measured when the ship arrifed at Pearl Harbor range from as high as 0.620 R/hr (Reference 85) to 0.1B3 R/hr (Reference 86). No steps to decontaminate the ship were taken en route to PearlfHarbor 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 230 ind was
