Detector

Halogen-quenched GM tube with thin mica end window. Mica window density 1.5-2.0 mg/cm2. Effective diameter of window is 45 mm (1.77 in.). Side wall is .012 inch thick.
Operating Range
µR/hr – 1 to 50,000
CPM – 0.0 to 175,000
nSv/hr – 1 to 500,000
CPS – 0.0 to 2500
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
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. 3600 CPM/mR/hr (137Cs). Smallest detectable level for 125I is .02 µCi at contact.
Display
