How does aluminum protect against radiation?

Aluminum protects against radiation primarily through its density and atomic structure, which can absorb and scatter certain types of radiation, particularly gamma rays and X-rays. While it is not as effective as denser materials like lead, aluminum's lightweight nature makes it useful in applications where weight is a concern. Additionally, its ability to form a protective oxide layer prevents corrosion, ensuring long-term effectiveness in shielding environments. Overall, aluminum serves as a practical barrier in specific radiation protection scenariOS.
