Portal-type Pedestrian Radiation Monitoring System
Product Introduction
This product is independently developed and manufactured by Supersense Technology Co., Ltd. It utilizes a large-volume plastic scintillator detector and features integrated dose-rate measurement, enabling rapid and effective radiological screening of pedestrians and luggage. It is primarily installed at key access points in locations such as customs facilities, airports, transport stations, large-scale event venues, hospitals, nuclear power plants, nuclear material mining sites, and military installations.
Product Overview
Detector: Plastic scintillator detector; each unit has a volume of 15L. The system comes standard with two units (total volume: 30L) and features 5-sided, 5mm-thick lead shielding to reduce the false alarm rate.
– Energy range: 20 keV – 3 MeV
– Detection zone height: 0.1 – 2 m
– Detection zone width: 1.5 m (with detectors on both sides)
– Maximum allowable transit speed: 1.2 m/s
– Environmental adaptability: Temperature: -30°C to +50°C; Humidity: 30% – 95% RH
– Capable of distinguishing between naturally occurring radioactive materials and special nuclear materials
– False alarm rate: ≤ 1/1000
– Detection sensitivity: At a background radiation level of 0.2 μSv/h, the system will trigger an alarm within 1 second upon an increase of 0.1 μSv/h; detection probability is 99.9%
– Lower detection limit: < 100 nSv/h
– Compliant with national standard GB/T 24246-2009, "Monitoring Systems for Radioactive Materials and Special Nuclear Materials"
– Automatic background subtraction
– Modular design for easy assembly/disassembly, expansion, customization, and maintenance; high resistance to interference, suitable for operation in harsh natural environments
