Neither ship was positioned in the fallout area during BRAVO because of a miscalculation in predicting the fallout location and thus did not require major decontamination; nor did shot UNION contaminate either chip. YAG-40 had to be decontaminated following shot ROMEO, and both ships were decortaminated after shot YANKEE. Shot activities are summarized in Table 77.

By 25 May the average tcpside reading for YAG-29 was 0.007 R/hr, with average interior and below-deck readings of 0.002 R/nr. Thes? levels were expected to be down to 0.004 R/hr and 0.001 R/hr, respectively, at the time of arrival at’ Pearl Harbor, and 0.003 R/hr and 0.9005 R/hr at San Francisco. Crewmembers were expected to receive 0.5 to 1 R on the trip to San Francisco, Readings for YAG-40 were higher: 0.040 R/nr topside and 0.0038 R/hr inside on 25 May, with 0.025 R/hr and 0.004 R/hr axpected at Pearl Harbor, and 0.014 R/hr and 0.002 R/hr at San Francisco. tionai exposure for the crew was expected to be 3 to 5 R.
