3.2.18 USS SIOUX Dose Calculations Dose calculations for 1-2 March for personnel onboard the SIOUX 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 2-18) 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). from each source are summed and converted to a film badge dose. Contributions Cumulative film badge doses through 31 May 1954 are given in Table 3-18.
