A biref smmary of the basic physical fearutes of positron annihilation (PA) is presented. The information content of PA, the fate of positrons in condensed media, the formation of positron bound states and positronium (Ps) are considered in connection with the experimental techniques of PA. Representative applications of PA from the fields of physics, chemistry and medicine are given to illustrate the virtue of these techniques. Performance and sensitivity limits and the future perspectives of PA are also briefly discussed.
