Definition
A beta ray is a stream of beta particles, which are high-energy electrons or positrons ejected from the nucleus of an atom during radioactive decay. ☢️ These rays have a greater range and penetration power compared to alpha particles but are less penetrating than gamma rays. Picture it as a swift-moving stream of tiny bullets. When beta rays interact with matter, they can cause ionization, potentially leading to cellular damage in living organisms. Beta rays are used in various industrial and medical applications. For example, they can be used to treat certain eye and bone diseases, as well as in quality control to test the thickness of materials.
