Exceeding Dose Rate Alert Threshold (w/ALERT version)
Gamma-Scout also provides information on the cumulative dose received by the device, measured
on the time axis. As described below, users can stop summation, restart from an old level or delete
and restart from zero. Because of this and other reasons, the accumulated dose cannot be used as
a certified “personal dose meter.”
GAMMA-SCOUT® w/ALERT features an acoustic signal that sounds when the dose rate exceeds a
specified level. The default alert level is 5 µSv/h. If this value is exceeded by measurement of radi-
oactivity, this will be shown with an additional symbol in the display. The symbol in the display
can be erased by pressing the button twice.
Individual Programming of Dose Rate Alert Level
Press the button once to switch to the “log frequency” mode (see page 12). Pressing the button
a second time switches the device to “alert level” mode. The set level shows in the display. Press
the or the button to increase or decrease the threshold respectively. The new value appears
blinking in the display. The lowest possible threshold setting is 0.1 µSv/h, the maximum is 2 mSv/h.
The step change is 0.1 µSv/h at the lower level, becoming wider higher up the range (try this). If the
AOFF setting is selected, the dose rate alarm is disabled. Press the button to enter (save) the
new threshold value.
