← ScienceWhich outcome occurs when a sealed americium-241 smoke detector reaches end-of-life?
A)Ionization chamber current decreases✓
B)Alpha particle energy increases
C)Detector voltage steadily increases
D)Beta decay converts Am into Pu
💡 Explanation
The alpha source decays; therefore, the ionization chamber current decreases because fewer ions are generated. Alpha emission diminishes, rather than beta decay causing transmutation, thus ionization cannot be sustained as activity falls with radioactive decay.
