Abstract
A method and apparatus for sterilization of webs and products made therefrom using electron beams (ebeams) is provided. A controller is configured to modulate an ebeam to ensure that a non-continuously moving web is sterilized within a desired range of exposure. During sterilization in place operations, manifolds are configured to operate to ensure that sterilants do not enter an irradiation zone to prevent damage to ebeam emitters.
