Precise Gamma Radiation Monitoring for Shelters, Security, and Monitoring Systems

The PoliProbe™ G1 Smart Probe is a professional gamma radiation probe designed for continuous measurement of ambient dose equivalent rate and accumulated ambient dose equivalent. Equipped with an energy-compensated Geiger-Müller tube, it delivers reliable measurements across a wide measurement range and is suitable for both fixed and mobile radiation protection applications.

The Smart Probe has been specifically developed to enhance existing systems with advanced radiation monitoring capabilities or to serve as an external sensor integrated into security, measurement, and monitoring solutions. This makes it ideal for both new installations and the retrofit of existing systems.

Designed for Shelters and Critical Infrastructure

In bunkers, protective shelters, and other security-critical facilities, continuous monitoring of ambient radiation is an essential part of modern protection concepts. The PoliProbe™ G1 can be deployed as an external gamma probe to continuously monitor radiation levels and transmit data to higher-level monitoring or control systems.

Its compact design makes it ideal for integration into:

• Protective shelters and bunker systems
• CBRN and NBC protection systems
• Fixed radiation monitoring installations
• Mobile response systems
• Security and alarm systems
• Industrial monitoring and measurement solutions

Function and Operating Principle

The PoliProbe™ G1 continuously measures gamma radiation and calculates both the current ambient dose equivalent rate and the accumulated ambient dose equivalent. An integrated microcontroller processes measurement data in real time using statistical evaluation algorithms to ensure stable and accurate readings, even when radiation levels fluctuate.

If predefined alarm thresholds are exceeded, the probe immediately alerts users through:

• Visual LED indicators
• Audible alarm

Measurement data can be transmitted continuously to an external system for real-time monitoring, visualisation, and documentation.

Flexible System Integration

The PoliProbe™ G1 does not include its own power supply and is designed for operation with external systems.

It can be connected to:

• Industrial automation systems
• Security and surveillance systems
• Polimaster PoliPack BRD
• Custom control systems
• PC workstations

Communication interfaces include:

• USB
• RS-485

This enables seamless integration into existing security and monitoring networks.

User Software

The PoliProbe™ G1 User Software is included with the device.

The software provides:

• Live display of measurement data
• Ambient dose rate monitoring
• Alarm threshold configuration
• Probe configuration
• Convenient data evaluation on a PC

This makes the system equally suitable for permanent installations as well as maintenance and service operations.
