Portal-Type Radiation Monitoring System For Pedestrians/Luggage
Product Introduction
This product is independently developed and manufactured by Supersense Technology Co., Ltd. It is primarily installed at key entry and exit points—such as those at airports, seaports, railway stations, banks, immigration and security checkpoints, nuclear power plant control zones, nuclear waste processing facilities, and government offices—to monitor pedestrians and packages for the presence of radioactive materials. Featuring high sensitivity, a broad detection range, and rapid response times, the system offers advanced capabilities including automatic radiation alarms, data logging, automated image capture, and remote data management. If the radiation level detected from a pedestrian or package exceeds a preset threshold, the system triggers an audible and visual alarm, thereby preventing the spread of radioactive materials and contaminants.
