Radiation gate measuring principle by Berthold!
The system operates using high‑efficiency scintillation detectors capable of detecting gamma radiation throughout a wide range of energy. When a vehicle, container, or person enters the detection zone, photocells, installed at the detectors, trigger „Start“ and „Stop“ of the measurement. The system continuously determines both the natural background and the reference background, the latter being automatically recalculated for each passage to compensate for shielding effects caused by the load. The corresponding transmitter processes detector signals, evaluates transit speed and direction, and applies customizable alarm thresholds. After the object exits the detection zone, the system automatically calculates results and provides detailed measurement data.
The system software manages parameter settings, background tracking, alarm evaluation, data logging and reporting to ensure consistent and reliable operation.
Customer benefits
Quality and safety
- High sensitivity due to large‑volume scintillation detectors
- Versatile use e.g. for vehicles, goods and personnel
- Robust design for industrial and outdoor environments
Simple and intuitive operation

Measuring arrangements & function
Customised arrangements for your gate monitor
The detectors of the radiation gate monitor can be combined or reconfigured in terms of number and orientation to fit different site layouts and traffic needs. This flexible design allows easy expansion, maintenance, and upgrades while ensuring reliable radiation detection at entry points such as borders, ports, or secure facilities.
Arrangement with vertical detectors on both sides
- Automatic drive‑through radiation detection – no manual detection required
- Dual side monitoring for enhanced accuracy, with detectors positioned on both sides of the vehicle
- Immediate identification of radioactive materials before entering or leaving the facility
- Safe, fast and uninterrupted material flow during daily operation
Arrangement with top and one or two side detectors
- Enhanced detection for low‑profile or compact loads
- Space‑saving single‑side installation for narrow or wall‑mounted setups
- Improved sensitivity from above when sources may be positioned higher inside the load
- Flexible setup for special application
RadSpect - the Radiation Gate Monitor
The RadSpect System
The system consists of three main components: the detector, the transmitter and the PC‑software.
The detector enables precise radiation measurement, while the transmitter processes the signal and manages system control processes the signal, monitors background radiation, calculates alarm thresholds and manages the alarm functions. The software is used for data display and post‑processing: it visualizes measurement values, allows exporting and storing data, supports report generation and enables integration with external systems such as networks, or printers. The system can be supplemented with various optional accessories, such as traffic lights or license plate recognition, allowing flexible configuration for different applications. Together, these modules form a robust and modular solution for accurate gate monitoring.
