Ranger Radiation Detector

This is the Ranger Radiation Detector

Designed for industrial use, it’s a lightweight yet rugged radiation sensor built for reliable surveys both in the field and at facilities. For detailed usage and setup, refer to the Ranger Radiation Alert manual.

Detector

Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.77 in.).

Operating Range

• mR/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
• Accuracy (Referenced to Cs137)
• Typically ±15% from factory, ±10% with NIST Source Calibration

 

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)
• Alpha

 

Selectable Alert Set Range

mR/hr .001 – 100 and CPM 1 – 350,000. Pulsating beeper sounds the alert. Device uses adjustable alert levels for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m. Alarm will sound when in Timer Mode when set alarm threshold is reached.

Anti-Saturation

Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.

Averaging Periods

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.
