| annihilation radiation |
The radiation produced when a particle and its antiparticle collide and destroy one another. In the case of collisions between electrons and positrons, gamma rays with a characteristic energy of 511 keV are produced.

| annihilation radiation |
is a form of photon radiation associated with a class of radioactive decays. Positrons, since they are antiparticles of ordinary electrons, cannot survive long in normal matter. Thus, positrons emitted during radioactive decay will slow down in matter until they reach thermal equilibrium. They combine with an electron in an annihilation event in which their combined mass (1.022 MeV) is converted to energy. ...
