The features of positron annihilation in KCl crystals before and after radiation exposure is investigated. A significant increase in the efficiency of the "ortho-vapor" process of positronium state conversion is detected. A model is proposed for taking part in the "ortho-vapor" conversion of conduction electrons drawn into the conduction band by a positron field that affords a qualitative interpretation of the results obtained and permits values of the electron concentration in a spur to be obtained.
