First robot dog to conduct radioactive cargo screening at key Guangzhou ports

(ECNS) -- Guangzhou Customs in Guangdong Province has introduced China's first radiation-detection robot dog to key ports in Foshan City, including the Zhujiang Freight Terminal and Beijiao Port, according to an official announcement on Thursday. 

Application of the quadrupedal robot marks a leap forward in automating high-risk inspection tasks. 

Measuring 65 centimeters in length, the robotic device integrates five sensor modules for radiation detection, gas monitoring, video surveillance, alongside temperature and humidity measurement. 

Equipped with audio-visual recording capabilities, it allows customs officers to remotely conduct radioactive cargo screenings and confined-space inspections.  

During a recent operation at Zhujiang Terminal, the robot approached a radioactive-alert-triggering import container, collecting three samples from 10 designated points. 

By automatically cross-referencing data with baseline standards, it pinpointed the radioactive source and quantified radiation levels. 

Real-time video feeds and metrics streamed to controllers 20 meters away revealed a gamma radiation dose equivalent rate spike about 150 times above local environmental norms. 

"Traditional manual inspections required officers to conduct time-consuming grid-based detection across multiple container points, exposing personnel to prolonged radiation risks," explained Li Longhai, deputy chief of equipment at Guangzhou Customs. "This robotic solution significantly enhances operational safety." 

The agency plans to expand the robot's application to facility patrols, empty container checks, and routine cargo examinations, aiming to streamline port operations while bolstering border security.
