Abstract

Technique of measurement energy density of high-current electron beam by means of dosimetric field of POR type (5-50 kGy) and standard scanner is presented. Also is shown that relative optical density of the film increases linear to increasing of absorbed dose in the range of absorbed dose 5-120 kGy. Correlation dependence of digital image parameter "light" of irradiated samples of dosimetric film on samples relative optical density is obtained. By means of correlation function, two-dimensional matrix of absorbed dose\´s values, corresponding with electron beam autograph on dosimetric film is derived. Elaborated technique allows to measure nonuniformity of energy density of pulsed electron beam with spatial definition less than 1 mm during the measurement of absolute values of energy density.
