3 Dose Calculations
3.2.8 USS
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 31 May 1954 are given in
Table 3-8.
