PM1703 High-Sensitivity Radiation Detectors



PM1703M personal radiation detector (PRD)

The PM1703 series consists of compact, belt- or pocket-clip radiation detectors widely used by security forces, emergency response teams, and operators of radioactive or recycling facilities in many countries.

The instruments are based on a CsI(Tl) scintillation detector, which provides high sensitivity to gamma radiation, significantly increasing the probability of detecting shielded or concealed radioactive materials.

All versions measure gamma radiation efficiently using a CsI scintillation sensor. The PM1703MO versions include an additional Geiger detector for accurate dose rate measurement, while the PM1703GNA versions incorporate a neutron sensor for detecting special nuclear materials.

Operating history is stored in the device’s non-volatile memory (up to 2,000 data points). The unit is compact, lightweight, and includes both audible and vibration alarms that activate when radiation levels exceed a preset threshold. The count rate is displayed on an illuminated LCD screen.

Optionally, PM1703 detectors can be supplied with an extension tube, useful for scanning scrap metal loads or recyclable materials, for example.

The PM1703, when mounted with an extension tube, is ideal for searching and detecting radioactive sources in facilities dedicated to the recovery, storage or handling of metallic materials for recycling, as required by RD 451/2020, on the control and recovery of orphan radioactive sources.

Data, including alarm times and levels, are stored in stable memory and can be downloaded to a PC via Bluetooth. They can also connect to mobile devices through the free Polismart® app.

PM1703M radiation detector with app

The available versions are as follows (all models feature Bluetooth communication):

  • PM1703MA-IIBT: Gamma radiation detector with a high-sensitivity scintillation sensor; the standard model for a wide range of applications.
  • PM1703MO-1BT, PM1703MO-IIBT: Versions that include an additional Geiger sensor for accurate dose rate measurement; the PM1703MO-IIBT version offers enhanced sensitivity.
  • PM1703GNA-IIBT, PM1703GNA-IIMBT: Versions incorporating a neutron detector for improved sensitivity to uranium and plutonium; the MBT version also includes a Geiger sensor.
