Instruments PM1703GN/GNA/GNM are designed to detect and locate even the slightest amounts of radiation emitting materials. Devices provide two operating modes: search for gamma and neutron radiation sources and measurement of dose equivalent rate. PRDs have shockproof hermetic case, fluorescent backlight and LCD display, non-volatile memory, audible, visual and vibrating alarms, user-friendly interface. PRDs of PM1703 series are recommended to non-technical personnel, no special knowledge or training is required.
Instruments are recommended for first responders, security guards, police, customs officers and border patrol. No special experience or training is necessary to operate the instrument.
Personal radiation detectors are designed for search, detection and localization of radioactive materials using method of impulse count analysis when registering gamma radiation with alarms and visualization on the LCD of the average gamma radiation count rate. Once the detector is turned on, it automatically starts taking measurements and storing the background radiation information. Instruments advanced processing algorithm enables user to update the background levels and setup alarm thresholds thus adjusting to the specific radiation environments and satisfy the requirements for the false alarm rate.
PM1703GN - model with γ-CsI (Tl) and LiI (Eu) detectors
PM1703GNA - model with γ-CsI (Tl) and LiI (Eu) detectors with increased sensitivity
PM1703GNM - modification is equipped with 3 detectors: CsI(Tl), GM counter, LiI (Eu) and USB interface
The instrument is equipped with three detectors:
Extremely sensitive scintillation counters allow detecting even the smallest amounts of gamma and neutron radiation emitting materials. Extra GM counter provides correct measurement of gamma radiation DER in the wide range up to 10 Sv/h (1000 R/h) and DE up to 10 Sv (1000 R).
