A product sterilization system includes a vault, a source of X-rays in the vault producing a field of X-rays in a treatment zone, a conveyance delivering products to the treatment zone for irradiation by the field of X-rays, a first X-ray detection subsystem in the treatment zone between the products and the source of X-rays, a second X-ray detection subsystem in the treatment zone behind the products, and a controller subsystem responsive to the first X-ray detection subsystem and the second X-ray detection subsystem and configured to determine an X-ray dose absorbed by the products.

Methods are provided that include positioning a disinfection apparatus in proximity to a cabinet, wherein the disinfection apparatus has a base supporting a germicidal source and the base includes components operationally coupled to the germicidal source for operating the germicidal source. The method further includes inserting the germicidal source into the cabinet such that at least a portion of the base is retained exterior to the cabinet and is operationally coupled to the germicidal source. Moreover, the method includes placing one or more items into the cabinet, closing the cabinet with the germicidal source and the one or more items in the cabinet and the base of the disinfection apparatus exterior to the cabinet, and then subsequently starting the disinfection source such that the germicidal source emits a germicide into the cabinet. Systems and cabinets used to conduct the aforementioned methods are also provided.
