Alpha particles are positively charged, comparatively heavy particles made up of two protons and two neutrons. Because of their size, alpha particles have little penetrating power and can be stopped by a sheet of paper or a layer or two of skin. However, if an alpha-emitting substance is inhaled or swallowed, it can do more damage than other radiation because of the mass and charge of the alpha particles. 1, record 1, English, - alpha%2Demitting%20substance
