Webalpha radiation will damage cells if the radioactive source has been breathed in as a gas or dust or if it is swallowed. Some of the effects that radiation has on a human body are shown below. Eyes WebApr 8, 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.

WebThe alpha radiation ionises the air within the metal chamber. A low electric voltage applied across the chamber causes a current to flow through the ionised air. When smoke particles enter the chamber, the current flow is altered and this in turn triggers an alarm.
