Personal Radiation Detectors

Personal Radiation Detector (PRD) is a pager size pocket high sensitive device 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


The gamma-neutron personal radiation detectors allow searching and detecting of radioactive and nuclear materials. The detectors have a hermetic and shockproof case and are ideal for operation in the unfavorable and/or harsh environment.

Personal Combined Radiation Detector/Dosimeter PM1703GNM is a highly sensitive device which is used to search for nuclear and radioactive materials and to measure dose and dose rate of gamma radiation. PM1703GNM allows to detect and locate both gamma and neutron radiation sources.

The modern gamma-neutron detector PM1703GNM can be used even by non-technical personnel. Ease of use and sensitivity make this instrument irreplaceable tool for police and for other specialists of emergency services, customs and border patrol. No special knowledge in radiation is required.

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.

PM1703MO-1BT - This modification is equipped with Bluetooth v 4.0 Low Energy Module (BLE112) and can exchange data with user’s mobile device in real time.
