3.2.16 USS PHILIP Dose Calculations

Dose calculations for the PHILIP 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 2-16) 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 3-16.
