Personal electronic alarm dosimeter

Technical specification
Detected radiation: gamma measured in Hp(10)
Detector: Si-diode
Measuring range:
– dose 1 µSv – 10 Sv
– dose rate: 5 µSv/h – 3 Sv/h
Calibration: better than ±5% (662 keV @ 2 mSv/h), Hp(10)
Energy response: Hp(10), 60 keV – 3 MeV, better than ±25%, up to 6 MeV, better than ±35%
Dose rate linearity: better than ±15%, up to 3 Sv/h

Audible alarms:
– eight separate alarms, sound level typically better than 85 dB(A) @ 30 cm
– integrated dose
– dose rate
– exceeding the dose
– dose rate above the flow rate at 3 Sv/h
– low battery 1 and 2
– defect
Alarm thresholds: 7 preset values ​​for integrated dose and dose rate, manually selectable by button

Button functions:
– the button on the front panel has the following optional functions:
– switching between dose and dose rate display
– on/off
– Chirp ON/OFF
– reset of the integrated dose
– change alarm thresholds
– activate the battery test

Note that active alarm thresholds and button function configuration can be changed using the ADR-1 readhead in combination with PC software
Dimensions: 78 x 67 x 22 mm
Weight: 80 g including battery
Temperature range: -20° to +50° operation, humidity up to 90% RH, non-condensing

Power supply: one standard AAA alkaline battery, lifetime typically 1800h in background field

Communication with the reader: infrared through the lower part; using the ADR-1 reading head in combination with computer software
