Applications & Uses: X-ray chamber inspection, Expanded Range up to 1000 mR/hr, Linear Response needs with Energy Compensation, Checking accelerator & x-ray shielding for leakage, Checking industrial gauges, such as moisture, density, or level gauges containing Cesium-137, Locating lost sources, Personal protection, Linear response detection applications, General surveying
Detector
Energy Compensated Halogen-quenched GM tube.
Operating Range
mR/hr – .001 (1µR) to 1000 mR/hr
µSv/hr – .01 to 10000
CPM – 0 to 450,000
CPS – 0 to 7500
Total Counts – 1 to 9,999,000 counts
Accuracy
Typically ±15% from factory, ±10% (NIST)
Anti-Saturation
Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
Energy Sensitivity
450 CPM/mR/hr referenced to Cs137. Detects gamma and x-rays down to 40 keV. Response is flat from 40 keV up.
Selectable Alert Set Range
mR/hr .001 – 1000 and CPM 1 – 450,000. 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.
