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.
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.
µR/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).
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 (Cs-137). Smallest detectable level for I-125 is .02 µCi at contact.
Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
Pulsating beeper sounds the alert. Adjustable alert levels are used for µR/hr / CPM, and nSv/hr / CPS.
Backlit liquid crystal display with mode indicators.
Red LED flashes with each count.
Sounds with each count (can be switched off for silent operation)
Two (2) AA alkaline batteries (included). Battery life is approx. 1000 hours at normal background radiation levels.
