What is an alpha particle?

An alpha particle is a fast moving packet containing two protons and two neutrons (a helium nucleus). Alpha particles carry a charge of +2 and strongly interact with matter. Produced during alpha decay, alpha particles can travel only a few inches through air and can be easily stopped with a sheet of paper.
