Which decay product creates risks inside sealed Am-241 smoke detectors?

💡 Explanation

Alpha particles cause material fatigue due to helium embrittlement, where alpha decay generates helium atoms which accumulate and form bubbles creating stresses; therefore fatigue occurs, rather than the others which are less impactful given the low activity and shielding.
