AP4000 Hand-Foot Surface Contamination Monitor
AP4000 (AP4000-T) Hand-Foot Surface Contamination Monitor integrates large-area dual scintillation detectors for α/β surface contamination screening of hands, feet, and clothing prior to exiting controlled radioactive areas. Multiple positioning sensors ensure correct posture, with a 10-inch touchscreen and voice guidance for operation and results.
It incorporates a personnel information management system with relational database binding personnel identity to measurement records, meeting IAEA GSG-7 traceability requirements. Dual identification modes: manual touchscreen lookup and optional IC/ID card reader.
Applications
The monitor features a dedicated DO interface that can be integrated with revolving doors, barrier gates, and other access control systems; it is primarily deployed at access points to nuclear power plants, radioactive medical facilities, radiation laboratories, nuclear fuel production sites, and nuclear waste treatment facilities.
