ELECTRON BEAM IRRADIATION AUTOMATIC MEASUREMENT APPARATUS USING RADIOCHROMIC FILM DOSIMETER AND METHOD FOR MEASURING ELECTRON BEAM QUALITY USING THEREOF

摘要

An apparatus for measuring the electron beam irradiation quantity automatically by using a film dosimeter and an electron beam irradiation quality testing method thereof are provided to increase processing amount per unit time and to manage and record the absorbed dose strictly. An apparatus for measuring the electron beam irradiation quantity automatically comprises a film dosimeter(1), a supporting body(2), a transfer unit(3), an image obtaining unit(4,4'), and a controller(5). The film dosimeter measures the radiation quantity of an electron beam irradiator(6). The supporting body keeps the film dosimeter in a reference position during a radiation process and supports the film dosimeter during a measuring process. The transfer unit transfers the supporting body continuously to a loading position, an electron beam irradiation area, and an unloading position. The image obtaining unit changes an image into a digital signal and stores the digital signal in a memory medium.
