WebAlpha particles are most commonly used in smoke alarms. These alarms contain a tiny amount of decaying Americium between two sheets of metal. The decaying Americium emits alpha radiation. A small electric current is then passed through one of the sheets and into the second one. When the field of alpha radiation is blocked by smoke, the alarm ... Web8 apr. 2024 · 3. Alpha radiation is labeled as "ionizing radiation" for a reason. An alpha particle passing through electrons disturbs the electrons greatly. But the alpha particle has very high mass and kinetic energy compared to the electrons, so the presence of a few electrons doesn't really affect the alpha particle.
