Regulatory and safety risk
Uncontrolled radioactive material can create a health, environmental, and reporting incident. The response can outlast the shift.
INDUSTRIAL SAFETY
Screen vehicles before they enter the yard.
RadCar is a vehicle radiation monitoring system for scrap yards, steel mills, recycling facilities, logistics parks, and border crossings. It detects, alarms, records, and gives the operator a clear next step.
WHY SCREEN AT THE GATE
A single source can become an expensive problem
A single orphan radioactive source in a scrap load can trigger a regulatory incident, contaminate a furnace, or shut down a production line. The cheapest place to catch it is the entrance, before the vehicle unloads.
Production risk
Melting a source can contaminate equipment and force a costly cleanup. The furnace may be down for weeks.
Operational risk
Without a gate check, you rely on drivers and visual inspection. Neither is reliable at vehicle volume.
SYSTEM
What's in the lane
RadCar is assembled from standard components. The site survey decides the detector count, lane layout, and mounting positions.
| Component | Role |
|---|---|
| Detector nodes | Radiation detectors mounted around the lane, calibrated against local background. |
| Edge gateway | Reads sensor data, parses vehicle state, calculates speed, and sends events. |
| Management platform | Stores passes, alarms, sites, devices, and audit records. |
| Industrial PC | Runs the operator UI in kiosk mode on the lane. No internet required. |
| Alarm and video | Pulsed audible alarm, visual banner, and camera linkage for evidence. |
| License and roles | Device-bound license, with admin, operator, and reviewer roles. |
CAPABILITIES
Built for a working gate, not a lab
Operators are busy. The system has to work with dust, vibration, power interruptions, and staff who did not design it.
01 / SENSORS
Dual photoelectric input
4-state parsing (none, front, both, rear), backward compatible with single-sensor firmware.
02 / SPEED
Speed estimation
Time between front and rear beam triggers, using configurable sensor spacing.
03 / ANOMALY
Anomaly detection
Stuck sensor, chatter, detector offline, overlapping vehicles, wrong-way movement, and serial silence.
04 / CALIBRATION
Threshold calibration
Per-site background measurement and alarm thresholds, recorded for acceptance.
05 / ALARM
Alarm workflow
Pulsed alarm, silence button with automatic timeout, and an event record that survives the shift.
06 / VIDEO
Video linkage
Captures the vehicle event for later review. The operator sees what triggered the alarm.
07 / OFFLINE
Offline operation
Local database and kiosk application. The gate keeps working when the internet does not.
08 / AUDIT
Audit and backup
Role-based access, audit log, and data backup/restore procedures.
09 / LICENSE
Licensing
Device fingerprint binding and a short license key for kiosk entry.
SCENARIOS
Where it fits
Any site that receives vehicles carrying material of unknown origin can use a gate check. These are the common deployments.
Scrap and recycling
Inbound loads from mixed suppliers, with high vehicle volume and limited time per check.
Steel and metallurgy
Furnace protection and contamination prevention. A single source can stop production.
Ports and logistics parks
Gate screening and event records for vehicles moving between sites.
Nuclear and research
Controlled material movement with audit trails and role separation.
DEPLOYMENT
From survey to handover
Most of the work happens before the first vehicle is screened. The installation itself is usually the shortest part.
STEP 01
Site survey
Lane layout, detector placement, power, network, and camera positions.
STEP 02
Installation
Detectors, edge gateway, industrial PC, alarms, and wiring.
STEP 03
Calibration
Background measurement, thresholds, speed parameters, and test passes.
STEP 04
Trial run
Real vehicles, alarm drills, and false-positive review before acceptance.
STEP 05
Training and handover
Operators, supervisors, administrators, documents, license, and support plan.
