The sterilization apparatus (1) comprises carrier sources (6,7) for generating charge carriers, and an acceleration device for accelerating the generated charge carriers on the outer wall of the containers (2). A transport device (19) moves the carrier sources relative to each other along a predetermined transport path (5). A holding element which holds the containers, is partially inserted into the interior of the container such that the holding element is brought into contact with the inner wall of the container, for sterilization of the outer wall of container. Independent claims are included for the following: (1) a plant for treating containers； and (2) a method for sterilization of containers, through accelerated charge carriers.
