Alpha radiation consists o helium nuclei an is readily stopped bi a sheet o paper. Beta radiation, consistin o electrons or positrons, is haltit bi an aluminum plate. Gamma radiation is dampened bi leid.

Beta pairticles are heich-energy, heich-speed electrons or positrons emittit bi certain types o radioactive nuclei such as potassium-40. The beta pairticles emittit are a furm o ionizin radiation an aa kent as beta rays. The production o beta pairticles is termed beta decay. Thay are designatit bi the Greek letter beta (β). Thare are twa furms o beta decay, β an β+, which respectively gie rise tae the electron an the positron.[1]
