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.
