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.
