The Radiation Alert® Frisker is a radiation contamination 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, we have created a rugged, ergonomic tool that addresses a number of radiological applications, but particularly those of first responders who need an instrument to hand that can quickly assess radiation hazards.

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.

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.

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

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.  energy response Cs-137
