WebAlpha radiation is composed of fast-moving helium nuclei ejected from the nucleus of heavy unstable atoms due to electromagnetic and strong interactions. Alpha particles consist of two protons and two neutrons and have a travel range of up to a few centimetres in the air. The process of producing alpha particles is called alpha decay. WebAn interesting thing about alpha particles is that they do not penetrate far through matter (unlike beta or gamma radiation). They are stopped by paper! Therefore an external … dyned online
