Systematic introduction
BG3400-215 Passage-type Pedestrian Radioactive Automatic Monitoring System is a set of automatic radioactivity detection system equipped with large volume and high sensitivity gamma-ray detector. It can detect pedestrians and carry-on baggage through the detection channel online and real-time, find trace radioactive substances carried, output alarm information, and complete the check-up. Storage of measured data. At the same time, the system can also be networked with the superior management system to form a remote real-time detection system platform. The system can be used in many places, such as airports, wharfs, ports and so on, to detect whether radioactive substances are carried in pedestrians and luggage.

Applications: Entry and exit corridors for stations, wharfs, airports, customs and other places.
System characteristics
The unique radiation background discrimination algorithm eliminates the interference caused by background radiation change in measurement by continuously detecting environmental background radiation fluctuations and automatically adjusting reference points, and solves the problem of the influence of background radiation fluctuations on the sensitivity of detection system.
_System adoption2Group of large scintillating crystal detector module, each group of detector crystal equipped with double photomultiplier tube to process signal, can greatly reduce interference and improve detection efficiency.30%；
The system uses infrared detectors to detect pedestrian passage, which can effectively distinguish the system in the background update mode and detection mode.
_The system background management computer software uses full Chinese operation, graphical interface, can real-time monitor the on-site personnel traffic and radiation alarm, and can store monitoring data, query and print monitoring reports;
Configurable high-definition camera, real-time capture of monitoring images, and achieve synchronous storage and query of monitoring images and alarm data; multi-point monitoring and system networking.
