Which risk increases when unshielded americium-241 is stored long-term?

💡 Explanation

Radiation-induced material degradation increases, because alpha decay emits high-energy particles causing displacement damage within the storage structure. Therefore, embrittlement worsens progressively rather than a sudden failure or criticality which Am-241 cannot sustain.
