Arktis - Model P-RPM-IDn -Pedestrian Radiation Portal Monitor
Detects radiological threats to protect airports, government buildings and other critical infrastructure. The Arktis P-RPM-IDn enables reliable and discreet screening of pedestrians and their luggage for radiological threats. Real-time spectroscopic analysis of the alarms enables high throughput, does not infringe on personal privacy, and has minimal impact on daily operations The system’s modular open architecture is the right solution for fixed installed indoor detection scenarios.
- Spectroscopic isotope identification
- NORM/Medical rejection
- User friendly Graphical User Interface (GUI)
- Browser based: runs on any operating system (desktops, laptops, tablets, (desktops, laptops, tablets, smartphones)
- Based on Arktis ’ digital detection technology
- Solid state 6LiF-based neutron detection
- Real time automatic data transfer to network and central alarm station
- Real time, multiple RPM management
- Elegant design
Arktis P-RPM-ID is an indoor RPM to detect radiological threats transported by pedestrians. The system allows detection at high throughput with remote operation. Ideal deployment location include building entrances, in front of security screening lines, at customs clearance, or at boarding gates.
- Fully autonomous, the internal CPU performs real time ambient spectrum acquisition utilizing natural radiation signature for calibration and stabilization.
- The acquired ambient radiation data is used for real time dose calculation and tuning of the alarm parameters when no gate occupancy is detected.
- The spectra acquired during an occupancy are compared with a wide library spectra, evaluating potential threats even in case of multiple radiation sources (masking) or concealment attempts (shielding).
- The browser-based user interface doesn’t require a specific operating system or screen size.
Gamma Detectors: 2-liter (10 x 40 x 5 cm3), Sodium Iodide Nal{TI) based detectors with integrated MCA (fast multichannel analyzer). Energy range from 30 keV to 3000 keV.
Neutron Detectors: Arktis M800 neutron detector based on natural helium and eLiF. Uses solid state Silicon Photomultiplier (SiPM) technology rather than obsolete high voltage discharge methods.
Minimum Detectable Activity: The system detects a wide range of radioactive sources, including:
