4.2 DOSE CALCULATIONS FOR USS SHEA (DM-30). The only documented fallout on SHEA was minor contamination following Shot UNION. Normal crew activities onboard SHEA would not have been altered because of this fallout. The daily film badge dose is calculated by muluplying the contributions to exposure, both topside and below (from table 3.2), by the appropriate time-averaged shielding factor or apportionment factor. The cumulative film badge dose for the crew of SHEA through 31 May 1954, by which time dose accrual falls below 1 mrem perday, is detailed in table 4.2. Table 4.2.
