AGDM® Ambient Gamma Dose Rate Monitor

Technical data

  • Detected radiation: X and Gamma (24.6 keV ÷ 10MeV )

  • Measuring range: 0.01 µSv/h ÷ 10 Sv/h

  • Measured quantity: Ambient dose equivalent rate H*(10)

  • Measurement principle: Dead time independent 

  • Detectors: 2 x GM tubes

  • Response time: ≤ 8 s (1 µSv/h ÷ 10 mSv/h),
    ≤ 2 s (10 mSv/h ÷ 10 Sv/h)

  • Accuracy :  5 % (respect to calibration direction)

  • Calibration:  5 % (@ 137Cs)

  • Over exposure: 50 Sv/h over 5 min without decrease
    in counting rate

  • Communication interface:  RS 485, EMI protected

  • Alert / Alarm thresholds: Programmable over entire range

  • Remote data / commands communication via 4G/LTE modem

  • Files format: ANSI 42.42
