Ranger EXP
The Ranger EXP is a maximum performance, lightweight, rugged nuclear radiation detector to use for surveys in the field or at your facility. The Ranger EXP is designed specifically for individuals operating in tough environments. The small, handheld Geiger counter offers excellent sensitivity to NORM and low levels of alpha, beta, gamma, and x-rays. The digital readout is displayed with a red count light and a beeper sounds with each count detected. Other features include an adjustable timer, selectable alert, and with the free Observer USB Software Family, you can download your collected data, and set alarms!
Applications & Uses: Surveying for NORM (Naturally Occurring Radioactive Material) contamination, Contamination surveys of packages, equipment, people, etc., Regulatory inspections, Scrap Metal Screening, Low energy radionuclide detection
Detector
RAP-RS2 Probe – External Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.75 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
Built-In Efficiencies
Sulfur (35S), Strontium (90Sr/y), Cesium (137Cs), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt (60Co), and Alpha
Selectable Alert Set Range
mR/hr .001 – 100 and CPM 1 – 350,000. 70db @ 1m. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 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.
