Alpha particle - Wikipedia
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. [5] They are generally produced in the process of alpha decay but may also be produced in other ways.

Alpha Particles | Properties, Sources & Uses
2024年5月29日 · Alpha particles, also known as α-particles, are a type of ionizing radiation predominantly emitted during the radioactive decay of some heavy elements. They are highly intriguing to physicists and engineers alike because of their properties, sources, and various applications in science and medicine.
Alpha Radiation | Definition, Decay & Characteristics ...
Alpha radiation consists of alpha particles, that are energetic nuclei of helium. The production of alpha particles is termed alpha decay. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus.
Alpha Particles Properties and Applications - Open MedScience
Alpha particles are a form of ionising radiation emitted from the decay of certain radioactive elements, notably heavy metals like uranium and radium. Each alpha particle comprises two protons and two neutrons, making it identical to the nucleus of a helium atom.
