The Radiation Alert® Frisker is a radiation con***ination instrument that has been designed to meet the demands of today’s radiation responder. By integrating the latest electronics with a proven and dependable Geiger-Mueller detector, S.E. International has created a rugged, ergonomic tool that addresses a number of radiological applications.
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).
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.
Anti-Saturation
Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
Alert
Pulsating beeper sounds the alert. Adjustable alert levels are used for µR/hr / CPM, and nSv/hr / CPS. 
Display
Backlit liquid crystal display with mode indicators.
Count Light
Red LED flashes with each count.
Audio Indicator
Sounds with each count (can be switched off for silent operation)
