CASTLE, BRAVO reconstructed fallout at H+3; 0945 local time (R/hr). Reconstruction is by NRDL and shows gamma field levels that would have existed had the fallout been on land areas (source: Reference 53). Washdown on the ships was effective, but some problems did arise. On the Bairoko, one of the two ships most seriously exposed, the regular wash down equipment was secured after 2 hours and firehoses were then used on exposed areas throughout the day. made in gutters on the flight deck. a flight deck drain. At that time readings of 5 R/hr were A reading of 25 R/hr was recorded in The ventilation system was closed at the onset of th fallout, preventing much contaminated material from being carried below decks. The captain reported that the engineering spaces never exceeded readings of 0.008 R/hr (Reference 80). The Bairoko was able to launch helicopters at 1015 to retrieve the firing party still in the firing bunke on Eneu. The retrieval was completed at 1230.
