Core Viewpoint - The Guangzhou Customs has developed the first radiation detection "robot dog" for national customs, which is now in use at various ports in Foshan, enhancing safety and efficiency in customs operations [1]. Group 1: Technology and Functionality - The "robot dog" measures 65 centimeters in length and integrates five sensors and functional modules, including radiation detection, gas detection, video monitoring, and temperature and humidity monitoring [2]. - It is equipped with an audio-visual law enforcement recording device, allowing for remote operation by customs officers for tasks such as radioactive cargo detection and safety inspections in confined spaces [2]. Group 2: Operational Impact - In a recent operation at the Pearl River freight terminal, the "robot dog" detected radiation levels in an imported container, with gamma radiation dose rates increasing from 0.11 μSv/h to 16.6 μSv/h, exceeding natural environmental radiation levels by 150 times [4]. - The use of the "robot dog" significantly reduces the time customs officers spend on detecting radioactive sources, which previously required extensive manual checks and posed risks of radiation exposure [4]. Group 3: Future Applications - Guangzhou Customs plans to expand the application of the "robot dog" in customs supervision, exploring its use in site inspections, empty container checks, and general cargo inspections to enhance the efficiency of customs clearance and safeguard national security [4].
