What are the effects of cosmic radiation on aluminum outdoor sculptures in high-altitude installations?

Cosmic radiation, a constant stream of high-energy particles from space, poses unique challenges for aluminum outdoor sculptures installed at high altitudes. Over time, prolonged exposure can lead to material degradation, including surface oxidation, discoloration, and reduced structural integrity. Unlike lower elevations, high-altitude locations lack sufficient atmospheric shielding, intensifying radiation effects. Aluminum, while lightweight and corrosion-resistant, may develop micro-cracks or become brittle under sustained cosmic ray bombardment. Artists and conservators must consider protective coatings, alloy adjustments, or strategic placement to mitigate these risks. Understanding these effects is crucial for preserving public art in mountainous or elevated urban environments.
