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 . 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 tool that addresses a number of radiological applications.
The Radiation Frisker detects alpha, beta, and gamma with an
assortment of units of measure, customizable alarm levels, and a backlit
display.

Detector

Internal Halogen-quenched, uncompensated GM tube with thin
mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter
of window is 45 mm (1.77 in.).

Calibratable 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 (Cs

Typically ±15% from factory, ±10% with NIST Source
Calibration

Energy Sensitivity

Detects Alpha down to 2 MeV. Detects Beta down to .16 MeV;
typical detection efciency at 1 MeV is approximately 25%.
Detects Gamma down to 10 KeV through the detector window.
