Abstract

A mobile electron beam radiation sterilizing apparatus includes a movable chassis vehicle; a cabinet body installed on the chassis vehicle; an electron accelerator, which generates electron beam for articles to be radiation-processed, wherein the electron accelerator is provided in the cabinet body; an accelerator control box, which controls operation of the electron accelerator, a radiation shielding system comprised of: a stationary shielding body covering the electron accelerator; a pair of rotatable shielding doors, through which a passage is formed for an article to be processed to enter or exit, rotatably connected to the stationary shielding body; a motor for switching on and switching off the rotatable shielding doors.
