Personal Radiation Detectors

Personal Radiation Detectors (PRDs) are pager size pocket high sensitive devices for the search for the nuclear and radioactive materials. The high sensitivity and fast response time to the variations in the ambient radiation levels clearly distinguish PRDs from family of the electronic dosimeters which are mainly used for the precise dose and dose rate measurements.

The PRDs are carried in pockets or clipped to a belt. They automatically monitor environment and alert user in case of the radiation danger.

The main features of Polimaster’s Personal Radiation Detectors are:

  • Gamma and gamma/neutron radiation detections;
  • High sensitive, small and lightweight;
  • Non-volatile memory to store history events data;
  • Low power consumption;
  • Easy-to-use, two-button interface;
  • Reduced user training;
  • PC communication interface;
  • Capability to record gamma spectrum and transfer data to PC or PDA for radionuclide identification analysis*
    * Bluetooth enabled models


PM1703MA-II and PM1703GNA-II are a brand-new PRDs of well-known PM1703M/GN Series. Instruments are extremely sensitive and power-safe, designed for detection and localization of radiation sources in different environmental conditions by first responders.

New PRDs PM1703MA-II/GNA-II have significant competitive advantages, such as: special detection algorithm (suppress NORM algorithm), which allows excluding alarm signal when the natural gamma background value increases and NORM are detected; USB channel for data transmission to PC.

As well as previous well-known modifications of this Series, PRDs continuously monitor the environment for radiation, evaluate dose equivalent rate (DER) and alert the user with a visual, audio and/or vibrating alarm if a radiation source is detected.

The PM1703MO-1 and PM1703MO-2 instruments combine features of both Personal Radiation Detector (PRD) and Dosimeter in one housing.

Each instrument is equipped with two detection modules: highly sensitive CsI(Tl) scintillation detector and small-sized GM tube detector. CsI(Tl) scintillation detector allows to search for radioactive and nuclear materials and GM tube detector allows to measure dose rate of gamma radiation in the wide energy range.

In PM1703MO-1 modification bluetooth 4.0 is compatible with Microsoft operating system (mod.PM1703MO-1BT) .
