Operation Principle

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.

Benefits

• due to special detection algorithm, devices are able to detect smaller excess in 2-5 times of gamma radiation above the natural background within the time normalized by standards. On the other hand, it enables to alarm in shorter time in comparison with the requirements of the standards
• due to operating time from one AA battery up to 1000 h., benefit in operating cost of the device over 6-year period is achieved: for РМ1703 series  (PM1703^®) – not more than 50 dollars, for other competing devices – 180-1000 dollars
• at the same time devices of the PM1703 series (PM1703^®) remain one of the smallest PRDs in the world
• devices of PM1703 series (PM1703^®) is the best value for reasonable price
