Initial and final state radiation Initial and final state radiation In particle physics, initial and final state radiation refers to certain kinds of radiative emissions that are not due to particle annihilation. It is important in experimental and theoretical studies of interactions at particle colliders. Particle accelerators and colliders produce collisions (interactions) of particles (like the electron or the proton). In the terminology of the quantum state, the colliding particles form the "Initial State". In the collision, particles can be annihilated or/and exchanged, producing possibly different sets of particles, the "Final States". The Initial and Final States of the interaction relate through the so-called scattering
Nuclear Power and the Environment ejected by the nuclei of some unstable atoms that are large subatomic fragments consisting of two protons and two neutrons), beta particles (subatomic particles ejected from the nucleus of some radioactive atoms that are equivalent to electrons), gamma particles (electromagnetic energy photon) and energetic neutron radiation (energy released from an atom in the form of neutral particles called neutrons). The second half focuses on knowledge of radiation introduced into the environment and humans. Flower's and his team concluded in 1976 that low levels over a long exposure time can prevent a cell from dividing or further damaging genetic information. Other
