SE International Radiation Alert Frisker Radiation Detector (50 mR/h)

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.

Accuracy (Reference to Cs137): Typically ±15% from factory, ±10% with NIST Source Calibration NIST Calibration

Anti-Saturation: Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.

Display: Backlit liquid crystal display with mode indicators.

Alert: Pulsating beeper sounds the alert. Adjustable alert levels are used for µR/hr / CPM, and nSv/hr / CPS.

Count Light: Red LED flashes with each count.

Audio Indicator: Sounds with each count (can be switched off for silent operation)

Power Requirements: Two (2) AA alkaline batteries (included). Battery life is approx. 800 hours at normal background radiation levels.

Temperature Range: -10° to +50°C (14° to 122°F)

Humidity: 10% to 70% Non-Condensing.

Weight: 217 g (7.7 oz.)

Size: 276 x 44 x 64 mm (10.88 x 1.75 x 2.5 in.)

Includes: Carrying Case, Lanyard, Batteries, and Protective Boot. Protective boot fits most industry standard dose rate and compensation filters.

Options: NIST Calibration
