7.2.4 Measurements
The manufacturer of the detector recommends calibration by using 137Cs emitting 662keV gamma particles
with a dose rate in the following range: from 3 to 6 mSv/h and 60 seconds irradiation time.
Once the calibration factor is adjusted, we suggest validating an uncertainty below 10% from measurements
at 20%, 50% and 80% of the global dose rate range.
Irradiation duration must be adjusted in function of the dose rate to reach a sufficient counting statistic.
