Fresh-water flushing and repainting, however, were required following decontamination. In dry dock, steam was utilized to remove grease and oil from bearing surfaces. As expected, the most difficult items to decontaminate were canvas covers, tarpaulins, ropes, and fabric bumpers. In most cases, these items were simply moved to a storage area on Parry and the radioactivity allowed to decay (Figure 38). Versene scrubbing was attempted on the large canvas bathtub on the flight deck of the Bairoko, but was abandoned when it was found that the treatment dissOlved the radioactive particles and caused a spread of contamination and an increase in contaminated areas. Equipment Decontamination Other than for marine equipment, little decontamination was attempted at Bikini. Construction and technical equipment was washed and isolated 150
