Personal Combined Radiation Detector/Dosimeter PM1703MO-II BT (PM1703®)

Category: Gamma PRDs

PM1703MO-II BT is a personal combined radiation detector/dosimeter with improved search algorithm and NORM rejection function. The instrument provides fast and reliable search of nuclear materials, continuous monitoring of the environment for radiation, alert the user if a radiation source is detected or any of the of the preset radiation thresholds are exceeded.
PM1703MO-II BT is intended for everyday and/or emergency use by firefighters, military, police, and other first responding communities.

Operation Principle

  • The instrument has increased sensitivity due to two built in detectors: the highly sensitive CsI (Tl) scintillation detector for a fast response and location of radioactive sources, as well as energy compensated Geiger-Muller detector for high dose rate range and accurate measurement.
  • The suppress NORM algorithm allows excluding alarm signal when the natural gamma background value increases and Naturally Occurring Radioactive Materials (NORM) are detected.
  • The instrument displays the current level of gamma radiation background in numerical range from 0 to 9, that simplifies  visualization of the radiation dose rate for the user.
  • All the operations history is stored in the instrument non-volatile memory, protecting the data even when the battery is removed. The stored data can also be transferred to the personal computer via USB interface.
  • The instrument is equipped with Bluetooth channel and can exchange data with smartphones, that's very important for the day-to-day operation.
  • The instrument can be used both indoors and outdoors.


Optionally PM1703MO-II BT can be equipped with holster that provides additional protection for the instrument from weather, dust and occasional drops. It can be also fixed on the waist belt using belt loop.

Supress NORM algorithm

The suppress NORM algorithm allows excluding alarm signal when the natural gamma background value increases and Naturally Occurring Radioactive Materials (NORM) are detected.  If NORM are detected - green indication light is given. In case the other radionuclides types (IND, NUC, MED) are detected, red indication light and audio alarms are activated.

Communication with smartphone

PM1703MO-II BT can transfer data via Bluetooth® 4.0 to smartphones based on iOS (version 7.1.1 and higher) and Android (version 6.0 and higher) with  Polismart® Mobile App. Free Mobile App is available for iPod® touch, iPhone®, iPad®(iOS) and for AndroidTM mobile devices and can be downloaded from App StoreSM or from Google PlayTM.
