Radiation Alert® Frisker

Radiation Alert® Frisker

Sick of getting tripped up by cables? Want that free hand back? Tired of lugging around a meter the size of a lunch box? Presenting The Radiation Alert® Frisker. The Radiation Frisker detects alpha, beta, gamma, and X-ray. It has the ability to take readings in multiple different units of measure, customize alarm levels, and comes equipped with a backlit display. The Frisker is a light weight, single-handed radiation contamination instrument that has been designed to meet the demands of today’s radiation personnel for leak testing, surface monitoring, sample screening, and personnel screening. By integrating the latest electronics with a proven and dependable Geiger Mueller detector, S.E. International has created a rugged, ergonomic Geiger counter that addresses a number of radiological applications.

SPECIFICATIONS

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
Up to 50 mR/h. Instrument begins readings in µR/h and changes to mR/h at 1000 µR/h
Up to 500 µSv/h. Instrument begins reading in nSv/h and changes to µSv/h at 1000 nSv/h

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.

Accuracy
Reference to Cs137
Typically ±15% from factory, ±10% with NIST Source Calibration NIST Calibration

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

Display
Backlit liquid crystal display with mode indicators.

Alert
Pulsating beeper sounds the alert. Adjustable alert levels are used for
µR/hr / CPM, and nSv/hr / CPS.

Count Light
