3.2.3 USS APACHE Dose Calculations
The crew activity time-lines depicting periods spent above and below deck on 1-2
March are shown in Figure 3-!. Also shown is the average topside intensity during this
time period. For 1 March, periods during which the ship's washdown system was turned
on are annotated as obtained from the APACHE's deck log. It is assumed that when
the washdown system was on, all personnel were below. Other time periods above or
below deck for eating, working, and sleeping are also annotated.
On 2 March, a
"typical" work day is resumed, i.e., 9% hours on deck and 14% hours below.
