ABSTRACT:
Minimum electron energy is used for the sterilization of preformed containers in order to minimize the machinery size, cost and radiation shielding required for in-line use. The electron energy required is reduced by the use of one-sided (unilateral) irradiation wherein the dose delivered by the primary radiation to thicker portions of the containers is supplemented by the dose delivered by scattered electrons.
