3.2.14 USS LST-975 Dose Calculations Dose calculations for the LST-975 on 6-7 May, when YANKEE fallout was encountered, are detailed below. Time periods below deck are indicated by an asterisk (*). After 7 May, the daily film badge dose is calculated by multiplying the integrated intensities in Table 2-14 by the time-averaged shielding factor (0.46), and then by the film badge conversion factor (0.7). Cumulative film badge doses through 31 May 1954 are given in Table 3-14.
