METHOD FOR INACTIVATION BY ELECTRON BEAM IRRADIATION AND TREATMENT APPARATUS

摘要

The present invention provides a method for inactivation by electron beam irradiation, and a treatment apparatus, whereby irrespective of the shape of the object to be treated and/or the retention form of the object to be treated, microorganisms can be inactivated uniformly with a simple configuration, and also whereby damage to the object to be treated caused by electron beams can be reduced in spite of the use of electron beams. A treatment apparatus for inactivating microorganisms as in one embodiment of the present invention is provided with: a treatment chamber; an electron beam irradiation device for irradiating the inside of the treatment chamber with electron beams; a retaining unit for retaining the object to be treated, the retaining unit being furnished within the treatment chamber; and a gas nozzle configured so as to supply a predetermined gas that has been excited by electron beams to the object to be treated retained by the retaining unit.
