As with MOLALA, after deletion of outliers, the mean of the film badge doses is reasonablycloseto the total reconstructed dose. The dosimetry data for PC-1546 for two badging periods (24 February-6 March and 7 March-30 April) is plotted in figure 6.7. The numbersof valid cohort badges (N=4) for each period for the 62 personnel in this small ship weakens any inference that might be drawn from comparisons with the calculated dose for a typical crew member. Nonetheless, it is noteworthy that, within the available physical limits of a small PC, large differences in doses strongly imply unique activities. This was found to be the case in the first badging period for the cohort consisting of the Captain and Executive Officer. The Captain's badge, with a reading of 1600 mrem, was deleted as a result of recent telephone conversations with him, in which hestated that: On the afternoon and early evening of Shot BRAVO day, after turning northward to return to Bikini, PC-1546 was alerted by other ships in the vicinity to fallout over their intended route. Lacking a washdown system and the pumping capacity for effective use of hoses to wash down the superstructure, I directed the entire crew to go below decks while I conned the ship alone from the flying bridge. I wore rain gear and, where possible, maneuvered the ship under rain clouds to achieve some degree of washdown. The Captain further indicated that a group of four individually badged personnel with badge readings of 720 to 1175 mrem were his radsafe monitors who conducted topside surveys for him during this period. These are also excluded from the plot. For the remaining badges, there is good correlation with the calculated dose for the first badging period. The correlation for the second period is not good, but neither period provides sufficient numbersfor valid statistical inference. The film badge dosimetry for LST-1146 for the period 19 March-3 April is shown in figure 6.8. There were fourteen cohorts. Two of the badges were indicated as wet and are not included; the apparentassignment ofa dose of 80 mrem to these cohortsis also not included. As shown, the calculated dose of 190 mrem forthe typical crew member of LST-1146is somewhat on the high side of the twelve cohort badges. The dominant component of the calculated dose for LST-1146 personnelis from fallout experienced on 29 March while transiting from Enewetak to Bikini. As previously detailed in section 3.9, the time offallout cessation was 103
