Alpha particle radiation is equivalent to fast moving nuclei of which element?
Alpha particle to strict control of radioactive elements in the packaging of semiconductor materials, and the problem is largely considered to be solved. Alpha particle Alpha particles, also called alpha ray or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways. Alpha particles are named after the first letter in the Greek alphabet, α. The symbol for the alpha particle is α or α. Because they are identical to helium nuclei, they are also
Particle radiation Particle radiation Particle radiation is the radiation of energy by means of fast-moving subatomic particles. Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam. Due to the wave–particle duality, all moving particles also have wave character. Higher energy particles more easily exhibit particle characteristics, while lower energy particles more easily exhibit wave characteristics. Particles can be electrically charged or uncharged: Particle radiation can be emitted by an unstable atomic nucleus (via radioactive decay), or it can be the product from some other kind of nuclear
