Product Manual

The Radiation Alert 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. It detects alpha, beta, gamma, and X-ray and has the ability to take readings in multiple different units of measure, customize alarm levels, and comes equipped with a backlit display. By integrating the latest electronics with a proven and dependable Gieger-Mueller detector, S.E. International has created a rugged, ergonomic tool 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 1.77" (45 mm). Side wall is 0.012" (0.30 mm) thick.
Operating Range:	μR/hr: 1 to 50,000 CPM: 0.0 to 175,000 nSv/hr: 1 to 500,000 CPS: 0.0 to 2,500
Accuracy:	Typically ±15% from factory. ±10% (NIST)
Energy Sensitivity:	Detects Alpha down to 2 MeV. Detects Beta down to 1.6 MeV. Typical detection efficiency at 1 MeV is approximately 25%. Detects Gamma down to 10 KeV through the detector window. 3600 CPM/mR/hr (137cs). Smallest detectable level for 125l is .02 μCi at contact.
Anti Saturation:	Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
Alert:	Pulsating beeper sounds the alert. Adjustable alert levels are used for μR/hr / CPM and nSv/hr / CPS.
Display:	Backlit liquid crystal display with mode indicators
Count Light:	Red LED flashes with each count
Audio Indicator:	Sounds with each count (can be switched off for silent operation)
