3.2.10 USS GYPSY Dose Calculations Dose calculations for the GYPSY on 1-2 March when BRAVO fallout was encountered are detailed below. Time periods below deck are indicated by an asterisk (*). After 2 March, the daily film badge dose is calculated by multiplying the integrated intensity topside (Table 2-10) by the time-averaged shielding factor (0.46); the integrated intensity below is multiplied by the fraction of the day spent below deck (0.6). Contributions from each source are summed and converted to a film badge dose. Cumulative film badge doses through 31 May 1954 are given in Table 3-10.
