3.2.6 USS CURTISS Dose Calculations
Dose calculations for personnel onboard the CURTISS on 1-2 March 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 2-6) 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 3-6.
