Researchers from the University of Waterloo have created a lightweight alternative to traditional lead aprons used by X-ray technologists, aiming to alleviate chronic back pain caused by the heavy gear. The project, which has been in development for three years, was inspired by discussions with radiologists about the physical toll of wearing lead aprons. Tizazu Mekonnen, a chemical engineering professor, noted that many technologists retire early due to apron weight-related pain. The innovative solution employs tungsten nanoparticles, processed into a flexible polymer that is significantly lighter—one-tenth the weight of lead aprons. The research team, including PhD student Aklilu Messele, overcame numerous challenges in material selection and synthesis. Their findings, published in the journal Materials Today Physics, mark a significant advancement in radiation protection technology. The next phase involves scaling up for commercial production, with cost considerations being a crucial factor for adoption in hospitals. Additionally, the team sees potential for this material in blocking gamma rays, which are present in nuclear facilities.
