The Frisker - Pancake Radiation Detector.

  • Model: Frisker


Add to Cart:
The Radiation Alert® Frisker is a handheld, wand-shaped radiation detector, featuring digital display and an internal pancake G-M. This detector is ideal for general purpose survey in laboratory use, nuclear power plant frisking, emergency response, border patrol, customs inspections, airport security, and other applications.


Halogen-quenched pancake GM tube with thin mica end window. Mica window density 1.5-2.0 mg/cm2. Effective window diameter is 45 mm. 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
Typically ±15% from factory. , ±10% (NIST).
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.
Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
