“2AV0 FALLOUT EXPOSURES BRAVO was without question the worst single incident of fallout expo- aires in all the U.S atmospheric testing program. contours after 96 hours are shown in Figure 69. The accumulated dose Not only were U.S. mili- :ary personnel involved, but also foreign nationals and Marshall Islanders. The cumulative nature of the Consolidated List of CASTLE Radiological Exposures (Reference 13) makes it impossible to assign portions of the cersonnel exposure to BRAVO, as opposed to the CASTLE series as a whole. che microfilm file of cards (Reference 87) on which it is presumably based shows, in some cases, event-by-event exposures, and estimates were made for portions of the task force at the time. Other estimates have been or can be made for other personnel involved. 7ask Group 7.3 Exposures In summing up BRAVO operations, the Navy prepared a tabulation of the oxposures of the appropriate fleet units (Table 23), and the contribution co the BRAVO collective exposure by TG 7.3 forces can be derived from this. This tabulation was through 22 March and contains exposures received in the potentially hazardous decontamination activities and the survey visits by the crews of the Renshaw and the Philip to the contaminated islands of Rongelap Atoll. ENEWETAK-BASED PERSONNEL. Badges were exposed on Enewetak at fixed locations-and some of these, at least, are included in the microfilm file of 5x8 cards (Reference 87) from which Reference 13 is derived. Two of these badges, marked 103 and 106, were placed in the 8600th AAU area and the "Laundry Area;" they read 0.075 R and 0.110 R, respectively (Index 1020 control film 4904-10). The cumulative exposure record of units whose pres- ence became unnecessary after BRAVO, (that is, TU 2 and 3 of TG 7.1; (see Chapter 3) and probably left the PPG before the completion of the series, is consistent with the two badges above. A credible exposure for person- nel on Enewetak for the BRAVO period is 0.1 R. 235
