Abstract

The article focuses on the development and demonstration of COMRIS (COMpton camera for Radiation Imaging System), a graphical user interface (GUI)-based software designed to visualize the three-dimensional (3D) location of radioactive sources using synchronized output data from a Compton camera and a simultaneous localization and mapping (SLAM) device. COMRIS integrates gamma-ray event data from the Compton camera with 3D environmental models and positional data from SLAM to project Compton cones onto either point cloud data or voxelized spaces, enabling visualization of radiation sources even when hidden by objects. A demonstration using a remotely operated four-wheel drive robot equipped with a commercial Compton camera and a 3D LiDAR-based SLAM device successfully visualized a ^137Cs radiation source in both visible and obscured scenarios within a dark laboratory environment. The software’s flexibility allows for the combination of various Compton cameras and SLAM technologies, suggesting potential applications in nuclear decommissioning sites like Fukushima Daiichi and broader environments including aerial and underwater radiation mapping.
