What are aplha particles?
Alpha particles are generally produced during the alpha decay of the unstable nucle and this particle consists 2 protons and 2 neutrons in it.
These alpha particles have low penetrating power and will use as a smoke detectors and Ionising smoke detectors often use americium-241. Smoke entering the detector reduces the amount of alpha particles measured, causing the alert to sound.
Hence unique use of alpha prticle is as a smoke detector.
