GF-Instruments - Model SGR -Scintilation Gamma Radiameter

• 0.2 s response time
• Acoustic pitch response
• External audio output
• 64-point histogram
• Simple operation
• Long battery life for 3 - 6 working days

Applications

SGR scintillation gamma radiameter serves for fast and sensitive indication of gamma-ray sources.

Its main applications are:

• uranium ore prospecting
• search for hidden artificial emitters
• industrial and health purposes

SGR covers two basic ranges of measurements:

• quick and selective searching for radioactive sources with fast response, acoustic signalization and histogram of 64 measured values
• radiometric measurements (dose rate) with the support of point and continuous measurements

The dose rate measurement is based on evaluation of pulses collected in the energy ranges from 50 keV or 400 keV to 3000 keV according to recommendation of IAEA (International Atomic Energy Agency).

Standard accessories:

• Transport case
• Carrying belt
• User guide

Detector:

• NaI(Tl), dia 51 x length 51 mm (6 in³)

Sampling:

• 0.2 s to 120 s, standard or fast response

Measuring range and resolution:

• up to 250 µGy/h, resolution 0.1 nGy/h
• up to 250000 cps, resolution 0.1 cps
• 50 to 3000 keV or 400 to 3000 keV

Alarm:

• external audio output
• threshold setting from 50 - 2000 nGy/h
• variable frequency from 250 to 4000 Hz depending on the measured dose rate (upper frequency corresponds with 10-time multiple of the actual threshold)

Display:

• large graphical LCD display 320 x 240, white backlight

Power supply:

• 3 pcs of C cells (single use or rechargeable - NiCd, NiMh)
• working time 3 - 6 days

Casing:

• waterproof with increased resistance against mechanical damage and shocks

Dimensions & weight:

• 290x120x205 mm
• 2.3 kg

Ambient temperature:

• -20 to +60 °C
