7.1.1
Acquisition 1/5
Displays the current measurement values of the radon concentration in Bq/m³ (or
pCi/l), the temperature in °C (or °F), the relative air humidity in %rH, the air pressure
in mbar or hpa (or inHg) and the gamma ambient dose rate in nSv/h (if equipped
with dose rate module). When operating in Radon/Thoron discrimination mode,
the thoron value appears on Acquisition 1/5 instead of the gamma ambient dose
rate (DF2000). The radon and the thoron values are followed by the appropriate
statistical error bars.
Figure 10: Acquisition window 1/5
In order to record and display gamma dose rate measurement values it is required
to equip the
AlphaGUARD
with an additional module consisting of a Geiger-Müller
tube and associated electronics. The dose rate (gamma) as ambient dose
equivalent rate H*10 is displayed in the unit nSv/h. The measuring range of the
additional gamma dose rate detector is 20 nSv/h - 10 mSv/h.
The display value for the gamma dose rate is updated along with each
new measuring cycle.
