What is specific charge of alpha, gama and beta particle?

Gamma ray (also called gamma radiation), denoted by the lower-case Greek letter gamma (γ or {\displaystyle \gamma } \gamma ), is penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nucleiAlpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. A beta particle, sometimes called beta ray, denoted by the lower-case Greek letter beta (β), is a high-energy, high-speed electron or positron emitted in the radioactive decay of an atomic nucleus, such as a potassium-40 nucleus, in the process of beta decay.
