3.2.8 USS ESTES Dose Calculations Dose calculations for the ESTES on 1-2 March 1954 are detailed below. For | March, separate calculations are presented for the average crew and for crewmen involved in shipboard decontamination. For 2 March, it is assumed the "average" crew and "deck" crew had equal opportunity for exposure. 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 2-8) 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 3! May 1954 are given in Table 3-8.
