Abstract:
Orphan radioactive sources pose a significant environmental and human health threat. This study presents a novel, scalable detection system for localizing and identifying these sources within large areas. Our system integrates a network of radiation detectors with surveillance cameras, employing data fusion algorithms to analyze both radiological and visual data. This multi-sensor approach enables accurate estimation of radionuclide types and the assessment of associated radiological risks. Real-world experiments demonstrate the system's effectiveness in enhancing the efficiency and accuracy of orphan radioactive source detection, contributing to improved environmental monitoring and the mitigation of potential radiological contamination risks.
