Radiation - Radioactivity Detector
The Madoors USA Radiation and Radioactivity Detector is a passive in-vehicle and vehicle-mounted gamma and neutron radiation detection system used to find radioactive elements, special nuclear materials, radiation-contaminated bombs, and nuclear devices hidden in trucks, containers, passenger vehicles, vans, and freight vehicles — operating at speeds up to 20 mph (30 km/h) with a very low false alarm rate of 1:15,000, gamma spectroscopy logic, automatic license plate recognition, live video recording, side and general view cameras, source location profiling, UPS power supply, and Windows-based software with remote connection for maintenance and service. Deployed at customs facilities, border ports, sea ports, air transportation terminals, and land transportation checkpoints, the system is used by Presidency, Prime Ministry, military and security units, and Customs and Border Protection — detecting nuclear and radiological materials intended to be illegally transported into a country by land, sea, or air before they can cause mass casualties or disrupt national economies.
TECHNICAL SPECIFICATIONS
The Madoors USA Radiation Detector is a passive detection system — it does not produce X-ray images or active radiation. Instead, it captures and responds to the energy naturally emitted by radioactive sources passing by the detector panels — functioning in the same way as a radio receiver that responds to specific energy frequencies. The operator receives an indication of the energy power level from the detected source, with source location profiling identifying the position of the radioactive material within the passing vehicle.
The system detects both gamma radiation and neutron radiation — the two primary radiation types of concern for nuclear and radiological threat scenarios. Gamma radiation detection covers the wide range of radioactive isotopes that emit gamma rays, including natural radioactive materials, medical isotopes, industrial isotopes, and the weapons-grade special nuclear materials that represent the highest national security threat. Neutron radiation detection specifically addresses the neutron emission signatures of weapons-grade fissile materials — plutonium and highly enriched uranium — that are the primary concern for nuclear weapon and dirty bomb detection.
The gamma spectroscopy logic identifies the specific radioactive isotopes present in the detected source — distinguishing between benign naturally occurring radioactive materials, legitimate medical and industrial isotopes, and the special nuclear materials and radiation-contaminated bomb materials that require security response. This isotope identification capability is the primary false alarm reduction mechanism — the 1:15,000 false alarm rate is achieved through spectroscopic discrimination between threat and non-threat radioactive sources rather than responding to all radiation above a threshold level.
Operating speed of up to 20 mph (30 km/h) allows the system to scan vehicles moving at slow checkpoint approach speeds without requiring complete stopping — maintaining vehicle throughput at busy customs and border crossing positions. The detector panels are connected in sequence to an Ethernet switch that connects directly to a PC, existing network, or remote announcer — allowing distributed panel installations across a wide vehicle lane to feed a single centralized detection and display system.
UPS power supply ensures continuous detection operation during mains power failure — the critical reliability requirement for a border security system where any interruption in detection coverage creates an exploitable gap for illegal radioactive material transport.
KEY FEATURES
Gamma & Neutron Detection — Complete Radiation Threat Coverage
The simultaneous detection of both gamma and neutron radiation provides comprehensive coverage of the full nuclear and radiological threat spectrum — gamma detection for the broad range of radioactive isotopes including medical, industrial, and weapons-related materials, and neutron detection specifically for the fissile weapon-grade materials that represent the highest threat level. The combination of both detection modalities from a single system ensures that no nuclear or radiological threat type can bypass detection by presenting a radiation signature that only one modality would detect.
1:15,000 False Alarm Rate — Gamma Spectroscopy Discrimination The very low 1:15,000 false alarm rate — achieved through gamma spectroscopy logic that identifies the specific isotope rather than merely detecting radiation above a threshold — is the critical operational performance specification for high-volume vehicle scanning at busy border crossings and ports. Without spectroscopic discrimination, naturally occurring radioactive materials in cargo, building materials, fertilizers, and ceramic goods would generate constant false alarms that would either overwhelm the inspection capacity of the checkpoint or force threshold settings so high that genuine threats are missed. The spectroscopic discrimination directly maintains inspection credibility and operational efficiency.
Passive System — No Active Radiation Production
The passive detection principle — capturing the energy naturally emitted by radioactive sources without producing any active radiation — means that the Madoors USA detector does not require radiation safety exclusion zones, does not expose vehicle occupants or checkpoint personnel to any additional radiation, and does not require the complex radiation safety management associated with active X-ray and gamma scanning systems. This passive operation allows the detector to be installed at any checkpoint position without the infrastructure, safety management, and regulatory licensing requirements of active radiation-producing systems.
Up to 20 mph Operational Speed — Traffic Flow Integration
The 20 mph operational speed allows vehicles approaching and passing through the checkpoint to be scanned at normal low-speed checkpoint approach velocity without requiring vehicles to stop at the detector panel position. This moving-vehicle scanning capability maintains the traffic flow of the checkpoint — vehicles that are not flagged by the radiation detector proceed to the standard customs inspection without an additional stop specifically for radiation scanning.
Source Location Profiling — Pinpoint Material Position
The source location profile capability identifies the position of the detected radioactive source within the vehicle — front, rear, left, right, or specific cargo position — providing the customs officer with precise information about where the radioactive material is located before the vehicle is opened for physical inspection. This location information directly reduces the time required for the physical inspection by directing inspectors to the specific area of the vehicle where the source is detected.
Automatic License Plate Recognition — Vehicle Identity Coupling
The automatic license plate recognition system couples each radiation detection event with the vehicle registration number — providing the complete documentation required for customs enforcement action, national security intelligence, and post-incident investigation. Plate recognition also supports comparison against watchlists of vehicles of concern — automatically flagging vehicles that have been identified in previous intelligence as potential nuclear or radiological material transport suspects.
Live Video — General & Side View Cameras
The live video recording from both general viewing and side view cameras provides visual documentation of every vehicle that triggers a radiation detection alert — confirming the vehicle identity, driver appearance, and approach behavior at the time of the detection event. This video evidence supports the enforcement action following a positive detection and provides the investigation record required for prosecution of nuclear material smuggling offenses.
Gamma Spectroscopy — Isotope Identification
The gamma spectroscopy logic identifies the specific radioactive isotope present in the detected source — providing the critical discrimination between NORM (naturally occurring radioactive material) such as potassium-40 in fertilizer, legitimate medical isotopes such as technetium-99m in patients returning from nuclear medicine procedures, industrial isotopes, and the threat materials including weapons-grade uranium, plutonium, and radioactive bomb contaminant isotopes. This identification allows the operator to clear non-threat detections immediately without requiring physical inspection — maintaining throughput for the non-threat majority while escalating confirmed threat detections to full physical inspection and law enforcement response.
Remote Connection — Maintenance & Service
Remote connection capability allows Madoors USA engineers and technical support to access the system software remotely for maintenance, software updates, diagnostics, and fault resolution — reducing the service response time and eliminating the travel cost for routine maintenance at geographically remote customs and border facilities. Remote maintenance directly maintains system availability and detection performance without depending on local technical expertise for all service events.
UPS Power Supply — Continuous Detection Availability
The UPS power supply maintains continuous detection operation during mains power failure — ensuring that there is no detection gap during power outages that could be exploited for radioactive material transport. Continuous availability is the fundamental operational requirement for a border security detection system — any known detection gap provides an exploitable window for illegal transport.
