Which risk increases greatly under ultraviolet radiation due to disruption of orbitals?

💡 Explanation

Polymer chain scission accelerates under UV because bond absorption induces **electronic excitation**, breaking chains, therefore weakening the material. UV interaction affects polymer chains rather than metals or ceramics, where different degradation mechanisms prevail.
