Taal ash shields radiation in facilities

Researchers at Ateneo de Manila University and National University-Mall of Asia Campus have discovered that Taal Volcano's volcanic ash can serve as an effective radiation shield in hospitals, industrial sites, and nuclear facilities.

The study highlights the potential of iron-rich minerals in Taal volcanic ash to provide strong radiation attenuation properties due to their high electron density and tight structure, making it a viable alternative to expensive and environmentally hazardous materials like concrete and lead.

According to the World Health Organization, exposure to ionizing radiation can cause serious health issues such as skin and blood damage, cataracts, infertility, birth defects, and cancer. This discovery aims to mitigate these risks while reducing costs associated with traditional shielding materials.

Further studies are needed to refine the durability and optimize the shielding performance of Taal volcanic ash, ensuring its practical application in various critical areas.

The research team emphasized that since volcanic materials are abundant in the tectonically active Philippine archipelago, this discovery offers a practical way to manage disaster waste while enhancing safety in essential facilities.
