Product Parameters

• Energy scale of gamma rays

  Uncertainty ≤ ± (5% + 20keV) or typical uncertainty ± (2% + 10keV) at 23±5°C within 100 to 10kcps

• Energy resolution of gamma rays

  Based on the technical parameters published by the sensor.

• Standard sensor: (Left window)Crystal 10X10X25.4mm CsI(Tl) with 2X9mm² SiPM energy resolution 10%
• Additional resolution degradation of the instrument (95% confidence level):
• where E is the peak center energy in keV.

• Gamma radiation absorbed dose rate (error exists)

  Energy spectrum mode: background ~ 1mGy/h, uncertainty ±15%@662keV
  Dose mode: background ~ 2mGy/h, same as above
  Compensated energy response: ±20% (80keV～1.5MeV), -23%～+43% (50keV～2MeV)
  Strong radiation alert: 1mGy/h～10Gy/h, -50%～+100%@662keV. Since energy compensation is not available at this time, the error may be greater at other energies.

• Gamma radiation equivalent dose rate (error exists)

  ≤1mSv/h, typical uncertainty ±15%
  > 1mSv/h, -50% to +100%
  Equivalent dose (typical value at ≤1mSv/h, directionality exists):HP(0.07), HP(3): ±30%, HP(10): ±20%
  Limit of equivalent dose accumulation: ~10Sv

• Measurement time

Energy spectrum accumulation time: settable from 1s to 86400s (maximum count rate of 80kcps for scintillation detector, maximum count rate of 10kcps for PIN detector).

Dose accumulation time:any time: since the last time the user cleared the accumulated dose, to view the accumulated dose, nonvolatile storage cycle ~ 1h, shutdown and save.

• Stability 

Temperature stability: -20～45℃, amplitude drift ≤±10%, energy drift ≤±5%.
 Long-term stability: typical amplitude drift ±10%/a, typical valuedrift ±5%/a.

• Standard sensor: (Left window)Crystal 10X10X25.4mm CsI(Tl) with 2X9mm² SiPM energy resolution 10% ; 3x3mm PIN detector
• Temperature range: -20～50℃(work properly ); -40～65℃ (performance not guaranteed )
• Humidity range: 0% to 100% ( for short term, when there is no condensation inside the device)
• Altitude: -2000m～8000m(Barometric pressure change rate＜10hPa/min)
• Waterproof level: IP65 (for short term, the rubber cap on the interface must be well-covered)
• Seismic resistance: 1g,20Hz,30min
• Shockproof: Any direction, 1.5m, without functional failure, but performance degradation (including loss of accuracy) or cosmetic damage may occur.
