PM1703MO-II BT – Personal Radiation Detector for Protective Shelters and Mobile Security

The PM1703MO-II BT is a personal gamma radiation detector with an integrated dosimeter, specifically designed for the rapid detection of radioactive materials and the continuous monitoring of personal radiation exposure. The device combines a highly sensitive CsI(Tl) scintillation detector with a Geiger-Müller tube, enabling both reliable source detection and precise measurement of dose rates up to 200 mSv/h and accumulated personal dose up to 10 Sv.

As part of the proven PM1703®-II series, the detector is capable of identifying even very small amounts of radioactive material. Thanks to its compact design and integrated belt clip, it can be comfortably worn on clothing and is suitable for both experienced radiation professionals and users with limited radiation protection experience.

Advantages of PM1703MO-II BT

Continuous Personal Protection

The PM1703MO-II BT continuously monitors ambient radiation and immediately alerts the user whenever predefined alarm thresholds are exceeded. Alarm notifications are provided simultaneously through:

• Visual indication
• Audible alarm
• Vibration alarm

This ensures reliable warning even in noisy, complex, or low-visibility environments.

Rapid Detection of Radioactive Sources

Its high sensitivity enables the PM1703MO-II BT to detect even very small quantities of radioactive material, supporting rapid localisation of potential radiation hazards.

An integrated NORM suppression algorithm distinguishes between Naturally Occurring Radioactive Material (NORM) and artificial radioactive sources. Natural background radiation is indicated by a green status light, while potentially hazardous artificial radiation sources trigger a red warning indicator together with an alarm. This significantly reduces false alarms and supports faster operational decision-making.

Designed for Mobile Operations

The compact housing allows the detector to be comfortably carried using its integrated clip. It is designed for reliable operation in demanding field environments.

Key features include:

• Impact-resistant housing
• IP65 protection rating
• Operating temperature from –40 °C to +50 °C
• Battery life of up to 1,000 hours

---

Communication & Data Logging

All measurements and alarm events are automatically stored in non-volatile memory with a capacity of up to 2,000 events, ensuring that data is retained even when the battery is replaced. Measurement data can be transferred via USB and processed according to ANSI N42.42.

The integrated Bluetooth® interface also enables wireless connection to the free Polismart® App for Android and iOS. This allows users to view measurement data, adjust device settings, and conveniently configure alarm thresholds.

Additional Features:

• View and analyse measurement data
• Configure alarm thresholds
• Transfer stored measurement records
• Manage operational data

Why choose PM1703MO-II BT?

The PM1703MO-II BT complements modern shelter and security concepts by providing a mobile solution for personal radiation monitoring.

While fixed radiation portal monitors supervise entrances and controlled access points, a personal radiation detector protects individuals both inside and outside protected facilities.

It is therefore particularly well suited for:

• Shelter personnel
• Emergency responders
• Critical infrastructure operators
• Security organisations
• Individuals requiring enhanced radiation protection
