Radiation Alert Monitor 200

Specifications:

Detector

Halogen-quenched GM tube with thin mica end window. Mica window density 1.5-2.0 mg/cm2. Effective window diameter is .360 inch. Side wall is .012 inch thick.

Operating Range mR/hr – .001 (1µR) to 200 mR/hr µSv/hr – .01 to 2000 CPM – 0 to 235,400 CPS – 0 to 3923 Total Counts – 1 to 9,999,000 counts

Energy Sensitivity

1070 CPM/mR/hr referenced to Cs137
Detects alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV is greater than 80%.
Detects beta at 50 keV with typical 35% detection efficiency.
Detects beta at 150 keV with typical 75% detection efficiency.
Detects gamma and x-rays down to 10 keV typical through the window, 40 keV minimum through the case.
(Ref to Cs137)

Accuracy of Radiation Detector Device

Referenced to Cs137
Typically ±15% from factory, ±10% with NIST Source Calibration NIST Calibration Additional

Anti-Saturation

Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.

Selectable Alert Set Range

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.
