SACE Physics — Stage 2

Nuclear Decay — Flashcards & Quiz

Nuclear decay is the spontaneous transformation of unstable nuclei into more stable configurations, releasing radiation. SACE Physics Stage 2 expects you to write balanced decay equations for alpha, beta-minus, beta-plus, and gamma emission, apply half-life to exponential decay calculations, and compare the penetrating power and ionising ability of each radiation type.
