Which outcome results when a portable X-ray fluorescence (XRF) analyzer's radioactive source undergoes alpha decay?

💡 Explanation

Reduced excitation occurs because alpha decay reduces the source's activity via a stepwise release of alpha particles, weakening the excitation field over time; therefore, reduced energy results, rather than changes to spectral resolution, temperature, or target materials.
