Abstract: A method for determining a level of exposure to radiation utilizes a radiation dosimeter (10) comprising a substrate (12) provided with a radiation sensitive layer or patch (14) having an optical density which varies in accordance with the degree of radiation exposure. In addition, the substrate is provided with optically readable coding (16a, 16b) which identifies one or more encoded mathematical parameters for enabling an automated calculation of dosage from a detected optical density change of the radiation sensitive material. Each dosimeter is provided with a unique identification code encoded in the bar coding on the dosimeter substrate, to enable memory storage of pre-exposure optical densities for multiple dosimeters.
