Radiation Alert Ranger
Applications:
• Detecting and measuring surface contamination
• Monitoring possible radiation exposure while working with radionuclides
• Screening for environmental contamination
• Detecting noble gases and other low energy radionuclides
Specifications:
Detector
Operating RangemR/hr – .001 (1µR) to 100 CPM – 0 to 350,000 µSv/hr – .01 to 1000 CPS – 0 to 5000 Total Counts- 1 to 9,999,000 counts |
Energy Sensitivity
Detects Alpha down to 2 MeV. Detects Beta down to .16 MeV; typical detection efficiency at 1 MeV is approx. 25%. Detects Gamma down to 10 KeV through the detector window. 3340 CPM/mR/hr (137Cs). Smallest detectable level for 125I is .02 µCi at contact.
Built-in Efficiencies
Sulfur (35S), Strontium (90Sr/y), Cesium (137Cs), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt (60Co), and Alpha
Display
Graphic LCD with Backlight
Anti Saturation
Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.
Averaging Periods
This radiation detector display updates every 3 seconds. At low background levels, the update is the average for the past 30-second time period. The timed period for the average decreases as the radiation level increases.
Outputs
USB for use with Free Observer USB Software for PCs
Bluetooth for use with the Free Observer BLE App for Android.
Count Light
Red LED flashes with each radiation event.
Audio Indicator
Internally mounted beeper (can be switched off for silent operation)
Power Requirements
USB Power or Two (2) AA alkaline batteries (included). Approx. 800 hrs @ background.
Accuracy
Reference to Cs137
Typically ±15% from factory, ±10% with NIST Source Calibration NIST Calibration Additional
Selectable Alert Settings
mR/hr .001 – 100 and CPM 1 – 350,000. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m. Alarm will sound when in Timer Mode when set alarm threshold is reached.
