Cosmic Rays to Revolutionize UK Infrastructure Monitoring: University of Glasgow Research Explores Non-Destructive Testing

(IN BRIEF) The University of Glasgow is pioneering a project to use cosmic rays for non-invasive structural assessments of the UK’s ageing transport infrastructure. Led by Dr. David Mahon and supported by a £459,000 grant from UKRI’s Science and Technology Facilities Council (STFC), the research focuses on adapting muography technology to detect early signs of structural fatigue in bridges. By analyzing cosmic ray-induced muon deflections, the project aims to create detailed 3D images without damaging the structures. In partnership with Transport Scotland, field trials will be conducted in Glasgow, with plans to enhance the portability and efficiency of muon detectors using machine learning. The initiative also aligns with net-zero goals by extending the lifespan of infrastructure and reducing the carbon footprint of construction materials. Lynkeos Technology Ltd will lead the commercialization of the updated technology.

(PRESS RELEASE) GLASGOW, 9-Dec-2024 — /EuropaWire/ — The University of Glasgow, a major research-led university, is leading a groundbreaking initiative to use cosmic rays as a tool for assessing the structural integrity of the UK’s ageing transport infrastructure. Spearheaded by Dr. David Mahon from the School of Physics & Astronomy, the project has secured £459,000 in funding from UKRI’s Science and Technology Facilities Council (STFC). This research aims to significantly lower the cost and environmental impact of maintaining road and rail bridges by enabling early detection of structural issues.

Dr. Mahon’s expertise lies in muography, a cutting-edge technique that leverages cosmic ray interactions to generate detailed 3D images of structures. Cosmic rays, upon colliding with atmospheric gases, release high-energy particles known as muons. When these muons encounter objects on Earth, their paths are subtly deflected, with the degree of deflection depending on the object’s density and composition. By analyzing these deflection patterns using advanced computational methods, muography provides non-destructive imaging capabilities that surpass traditional techniques like X-rays.

Lynkeos Technology Ltd, a spinout from the University of Glasgow, has already adapted muography to aid the nuclear industry in locating radioactive waste within concrete storage containers. Building on this success, Dr. Mahon’s team will now focus on refining the technology for applications in transport infrastructure. Over the next two years, the project will develop smaller, faster muon detectors that can function in real-world environments. Field tests, in collaboration with Transport Scotland, will be conducted on bridges across Glasgow.

“There are more than 74,000 road and rail bridges in the UK, many of which were constructed 50 to 60 years ago and are nearing the end of their intended lifespan,” Dr. Mahon explained. “Traditional inspection methods often require invasive procedures that can inadvertently weaken structures. Muography, already proven in the nuclear sector, offers a non-invasive alternative that could revolutionize how we monitor and maintain critical infrastructure.”

The new detectors will enable maintenance teams to identify structural fatigue and defects earlier than current methods allow, reducing repair costs and minimizing disruptions. Transport Scotland’s Chief Bridge Engineer, Hazel McDonald, highlighted the transformative potential of this technology: “Muography’s ability to provide deep insights into structural integrity could ensure the safety of public infrastructure while minimizing travel disruptions.”

In addition to enhancing detector portability and efficiency, the project will integrate machine learning techniques to accelerate cosmic ray data analysis. Following the research phase, Lynkeos Technology Ltd plans to commercialize the updated technology, making it accessible for widespread use.

Dr. Mahon emphasized the broader implications of the work, stating, “Prolonging the lifespan of infrastructure through non-destructive testing contributes to global net-zero ambitions. By extending the service life of existing structures, we can reduce the need for replacements, thereby decreasing the carbon footprint associated with the production of concrete and steel.”

This innovative research promises to reshape how infrastructure is maintained, providing safer, more sustainable solutions for the future.
