Personnel Hazard Alarm
The personnel hazard alarm is shown in Figure 41. By default, this alarm is triggered when gamma dose rate
exceeds 10 µSv/hr or neutron flux rate exceeds 25 nps/cm
2
. These thresholds (and units for gamma dose
rate) are adjustable from the Advanced Setup page by tapping the
Dose Alarms
button (Figure 42). With the
default values, the personnel hazard alarm will occur before the overrange alarm, which is fixed at an
exposure rate of 2 mR/hr (about 17 µSv/hr dose).
The personnel hazard alarm is indicated by messages on all screens that include the status header. It is
accompanied by short-duration audio and vibratory alarms (if enabled). Note that the gamma dose-rate
meter in the display header will continue to be updated with the current dose rate.
If the unit is configured to require all alarms to be acknowledged, a full-screen alarm (Figure 43) will be
displayed with audio and vibratory alarms if enabled that persist until acknowledged by the user. Messages
in the header will persist as long as the hazard condition exists.
