Abstract
Disclosed is a device for measuring radiation doses absorbed by a gel dosimeter, including in particular a polarizer for a light beam according to at least two distinct polarization angles, the polarizer being positioned between a light source and an optical detector, a unit for measuring the value of the intensity of the light beam, which intensity is measured by the optical detector, and a unit for calculating the value of a ratio of intensities of the light beam, which intensities are measured by the optical detector, for two distinct polarization angles of the light beam that is selected by the polarizer.
