Africa-Press – Sierra-Leone. <\/strong><\/span>Researchers from Ural Federal University (UrFU), working with an international team, have developed new environmentally friendly-materials to protect against nuclear radiation.<\/p>\n

The materials are made from mineral clays and glass industry waste, the study published in Journal of Science: Advanced Materials and Devices explained.<\/p>\n

Nuclear radiation takes three main forms:<\/p>\n

But tungsten is costly and lead is toxic, UrFU scientists explained.<\/p>\n

With a growing number of nuclear reactors and the increasing use of radioactive materials in medicine, the demand for new, safer shielding materials continues to rise, said Professor Oleg Tashlykov of UrFU\u2019s Department of Nuclear Power Plants and Renewable Energy Sources.<\/p>\n

UrFU researchers \u2014 in collaboration with scientists from Iraq \u2014 created ceramic materials capable of shielding radiation of varying intensities.<\/p>\n

The composition was based on a large-scale experimental methodology previously tested with natural minerals from Egypt, Jordan, Vietnam and other countries.<\/p>\n

\u201cWe mixed Iraqi clay with glass industry waste and a small amount of boric acid to create durable, inexpensive ceramics that can effectively block gamma radiation,\u201d said Karem Mahmoud, senior researcher at UrFU.<\/p>\n

\u201cAdding glass improves the tile\u2019s strength,\u201d he added. \u201cThis approach also recycles glass waste by integrating it into construction materials for radiation-prone facilities or X-ray rooms \u2014 without using lead.\u201d<\/p>\n

The materials \u2014 clay, glass waste, and boric acid \u2014 are widely available, and the production process of grinding and pressing at around114 MPa and firing at 550\u00b0C is simple.<\/p>\n

Although their shielding efficiency is lower than that of heavy oxide concrete, the ceramics are ideal where lead-free, moderately shielding, mechanically strong, and eco-friendly materials are preferred, Tashlykov explained.<\/p>\n

The next stage involves optimizing the ceramic for specific uses \u2014 achieving effective shielding with minimal weight and cost \u2014 and testing the materials under various conditions, including moisture, temperature cycles and radiation exposure.<\/p>\n

The research is being carried out with support from the Russian Ministry of Science and Higher Education as part of the Decade of Science and Technology initiative.<\/p>\n
