FILM-TYPE DOSIMETER AND METHOD FOR MEASURING DOSE BY USE OF FILM-TYPE DOSIMETER

摘要

PROBLEM TO BE SOLVED: To provide a film-type dosimeter capable of measuring a dose more easily and accurately, and a dose measuring method by the use of the film-type dosimeter.;SOLUTION: The dose of a radiation is measured from data on exposed light quantities from which variances in the thickness of a photosensitive layer have been excluded, by having a step for emitting the radiation to the film-type dosimeter, and making the film-type dosimeter generate density unevenness corresponding to the variations in the thickness of the photosensitive layer, a step for acquiring density distribution data on the density unevenness as first data, a step for emitting the radiation being a dose measuring object to the film-type dosimeter having the density unevenness and exposing the photosensitive layer to light, a step for acquiring density distribution data of the photosensitive layer exposed to the light as second data, and a step for finding the difference between the second data and the first data and extracting substantial exposed light quantity data.;COPYRIGHT: (C)2009,JPO&INPIT
