1. A radiation dosimeter, comprising:

  • a substrate;

    a layer of radiation sensitive material on said substrate, said radiation sensitive material having an optical density which varies in accordance with a degree of radiation exposure of said radiation sensitive material;

    optically readable first coding disposed on said substrate, said coding identifying encoded mathematical parameters for enabling an automated calculation of radiation dosage from a detected change in optical density of said radiation sensitive material; and

    additional optically readable second coding on said substrate for uniquely identifying the dosimeter.
