Radiation Portal Monitor
A Radiation Portal Monitor (RPM) is a large-scale, passive radiation detection system specifically engineered to automatically screen vehicles, cargo containers, and pedestrians for the presence of radioactive materials—without interrupting the normal flow of traffic. By operating in a non-intrusive manner, RPMs enable high-throughput screening while ensuring the safety and comfort of both operators and the public.
Deployed at strategic security checkpoints such as border crossings, seaports, airports, power plants, critical infrastructure, and government facilities, RPMs play a vital role in countering the illicit transport of nuclear and radiological threats. They form part of a layered defense strategy, complementing other security measures to prevent the smuggling or accidental movement of hazardous radioactive substances. This cutting-edge system seamlessly integrates state-of-the-art sensors with an intuitive user interface, allowing for smooth and efficient operation even in busy, high-traffic environments.
Stay Connected Anywhere with the RPM Mobile App
Our Radiation Portal Monitor Mobile App puts real-time security intelligence in the palm of your hand. Receive instant alerts the moment abnormal radiation levels are detected, no matter where you are. Monitor multiple RPM units remotely, view live detection data, and access alarm history anytime—without being tied to the control room.
Designed for fast decision-making and rapid response, the app integrates seamlessly with CCTV feeds, License Plate Recognition (LPR), and other security systems, giving you a complete situational overview on your smartphone or tablet. Perfect for border agencies, port authorities, and critical facility operators, this mobile solution ensures your security team can act swiftly, efficiently, and from anywhere.
