The EPD can perform the role of a ‘personal alarming’ EPD with alarm thresholds for
dose rate. There are two Hp(10)/h dose rate alarms and a single Hp(0.07)/h dose
rate alarm that can de displayed. The 2
nd
Hp(10)/h dose alarm has the higher priority
and should always be set to a higher value than the 1
st
Hp(10)/h alarm. The alarm
thresholds can be modified by the user, if required, but only when the EPD default
setting is set to ‘adjustable’. The user is barred from modifying the thresholds if the
EPD default is set to ‘not adjustable’. These default settings can only be set via the
IR communications link.
The dose rate alarm thresholds can be set using the button as follows:
10µSv/h, 50µSv/h, 100µSv/h, 500µSv/h, 1mSv/h, 5mSv/h, 10mSv/h,
50mSv/h, 100mSv/h, 500mSv/h, 1.0Sv/h
