GammaRAE II R

The GammaRAE II R is a gamma radiation detector and full-range dosimeter in a single instrument. Designed specifically to meet the needs of first responders, it has the rapid response of a detector and the accurate dose measurement of a dosimeter.

Key Features

• Sensitive CsI scintillator for excellent search capability and fast response
• Energy-compensated PIN diode sensor for high dose rate range and accurate dosimeter capabilities
• Prominent visible, audible and vibration alarms
• Alerts first responders to radioactive threats
• Accurately measures accumulated dose to the wearer
• Immersible in water for easy decontamination
• Top-mounted, invertable display
• Continuous digital readout in Rem/hour (μR/h & mR/h) or in Sievert/hour (μSv/h & mSv/h) and counts per second (cps)
• Two operation keys, simple intuitive programming
• Long calibration life
• Two AA Alkaline batteries last up to 600 hours
• Large, 30,000-point datalog capacity, downloaded via cable-free Bluetooth® connection

Sensor

• Energy Range: 0.06 to 3.0 MeV
• Dose Equivalent Rate (DER) Range for 137Cs: 1 μR/h to 600 R/h (0.01 μSv/h to 6 Sv/h)
• Accuracy of DER: ±20%
• Dosage Range: 1 μR to 999.9 R (0.01 μSv to 9.9 Sv)
• Background Reference: Background level reference set automatically on start-up (Search Mode only), plus user-initiated as needed
• Calibration: None required; periodic functional test recommended using 1 μCi and 16 μCi 137Cs check sources; factory calibration available if needed

Alarms

• Time to Alarm: <2 seconds
• Alarms
  • Loud audible buzzer (85+ dB @ 30 cm)
  • Built-in vibration alarm
  • Highly visible LED lights on both sides of LCD graphic display
• Alarm Settings
  • Dose Rate
    • Search Mode: Alarm threshold based on variations in local background level
    • Safety Mode: User-programmable low and high alarm thresholds based on dose rate
  • Dose
    • User-programable low and high alarm thresholds based on dose
    • Stay Time: Alarms vary by time (3 min to 2 hrs, once per minute; <3 min, once every 5 sec; 0 min and beyond, same as dose alarm)
