 | A charged particle emitted from a nucleus during radioactive decay, with a mass equal to 1/1837 that of a proton. |
| Particles (alpha, beta, neutrons) or photons (gamma) emitted from the nucleus of unstable radioactive atoms as a result of radioactive decay. |
| As used in regulation of domestic nuclear facilities and materials, the use of material control and accounting programs verify that all special nuclear material is properly controlled and accounted for, and the physical protection (also referred to as physical security) equipment and security forces. |
| Particle Accelerators (Atom Smashers) (from nuclear energy) -- Britannica Student Encyclopedia (675 words) |
| Particle accelerators are machines that accelerate charged particles in a high vacuum by electromagnetic interactions. |
| When the particles reach a high velocity, they are made to strike either on a fixed metal target or, in machines called colliders, on a beam of particles traveling in the opposite direction. |
| At the center of each atom is a tiny core called a nucleus that is surrounded by a cloud of electrons—electrically charged particles that move in the outer regions of the atom. |
