Radiation Portal Monitor - Model 4525-10500
CE Seal

The Ludlum 4525-10500 Radiation Portal Monitor (RPM) represents state-of-the-art technology at detecting orphan radiation sources. Ludlum has sold over 800 of these types of systems throughout the world to scrap yards, recycling companies, landfills, and foundries. The 4525 series detectors are ruggedized, large plastic scintillation systems that can be optimally arranged to monitor moving vehicles entering into the system.
Each detector system can be configured with either 2, 3, 4, 5, or 6 large detectors. The Model 10500 uses three. Real-time data acquisition and analysis is performed directly at each detector system and then reported to a central PC for logging, reporting, and alarm notification. Up to four detector systems (lanes) can be networked together via Ethernet or wireless to the central PC where vehicles entering from either direction can be monitored in real time. Each detector system additionally includes a remote control/enunciator panel to support operator awareness, alarm acknowledgement, and if necessary, backup operation in the event the central PC is unavailable.
Data from all system sensors are acquired and checked by powerful, field-tested, and time-proven algorithms designed to check each load vigorously in a multi-dimensional, multi-layered manner before declaring any load as clean. Any abnormality is immediately alarmed and annunciated both locally and remotely.  An optional camera system can capture the image of the offending vehicle and identify to the operator the location of the radioactivity on the image to facilitate a more immediate investigation. The image is included in the logged data for permanent record keeping.  Alarms can also be configured to automatically directly notify shift supervisors by email if desired.
The system is designed for ease of use and can be customized to accommodate a wide variety of site and application specific criteria.  Intuitive menus and controls combined with pre-defined automatic event handlers ensure each situation is handled properly and consistently.
