Radiation 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, 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.

Applications & Uses: Screening personnel and objects, such as packages, surfaces, and clothing, Surveying for NORM (Naturally Occurring Radioactive Material) contamination, Gross wipe counting, Contamination surveys of packages, equipment, people, etc., Regulatory inspections, Low energy radionuclide detection


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

Radiation Frisker Detector WindowµR/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).


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

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.
