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, and gamma and has an assortment of units of measure, customizable alarm levels, and a backlit display. 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.
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.
