F. Gamma Dose Estimates The gamma dose for each interval of the cases specified above is calculated from equation (4) (4) : D=R, x t t1 2 todt 1.2 = Rx! by multiplication of the approximate unit reference dose rate (R, ) from Table 4 by the time integral (1) from Table 5.

For the time interval of interest here, from fallout depostion on PATAPSCO on 2 March (H+32.5) to crew evacuation at Pearl Harbor on 10 March (H+233), the total cumulative doses estimated for each case are shown below. 17)
