PROBLEM TO BE SOLVED: To provide a method and a device for irradiating an object which stabilize the dose of an electron beam applied to the object and can minimize the fluctuation in surface doses. SOLUTION: In an electron beam uniform irradiator, an object 18 is irradiated from an electron beam irradiation section 16 after an electron beam generated by an electron gun 10 and controlled to a constant value by a grid voltage on the basis of the value of a current measured by a current controller 20 is passed through an acceleration tube 14, a deflection magnet 14 and the like. The irradiator is characterized in that an ampere meter 24 is placed directly at the front of the electron beam irradiation section 16 and that a means 21 for controlling the speed of an irradiation conveyor 17 which conveys the object 18 according to the fluctuation in the value of the current measured by the ampere meter 24 is provided so that the dose of the electron beam applied to the object 18 may be constant. |
