Portable underwater X-ray lets divers inspect submerged objects safely in real time

Oak Ridge National Laboratory (ORNL) has developed a groundbreaking portable underwater X-ray imaging system that allows divers to inspect the interiors of submerged objects in real time. This compact, lightweight device can be operated by a single diver and provides immediate images on-site, overcoming previous challenges of underwater X-ray imaging such as water’s weakening effect on X-rays and safety risks associated with gamma radiation. Specialized image processing techniques enhance clarity, enabling detailed inspections in difficult underwater conditions. The system has been successfully field-tested in ocean environments, demonstrating reliability and ease of transport and setup without heavy infrastructure. The technology holds significant potential for various industries, including maritime safety, infrastructure inspection, and oil and gas. It can be used to examine ship hulls, weld joints on bridge supports, pipelines, and oil rig structures more quickly, safely, and precisely than existing methods. Recognized with a 2025 R&D 100 Award and being commercialized by The Sexton Corporation, the system represents a major advancement by bridging laboratory X
