Which outcome occurs when isotopes decay within smoke detectors?

💡 Explanation

Alpha particles from Americium-241 decay ionize air molecules via ionization, generating a current; because airflow changes with smoke density, the current varies and alarms trigger; therefore, the alarm signals rather than neutrons triggering secondary reactions because americium emits only alpha not neutron radiation.
