    en.m.wikipedia.org/wiki/Alpha_particle

    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.

    For a given energy, alpha particles are much slower than beta particles, giving rise to greater impulses. Additionally, its double charge (+2 e) makes an alpha particle have a very high rate of energy loss in matter, thus making it heavily ionizing radiation.
