Abstract

A radiation dosimeter system and method for estimating a deposited radiation dose to an object involves locating at least one radiation dosimeter at the object. The radiation dosimeter includes a radiation sensitive medium having an optical property that changes due to the deposited radiation dose. An optical interrogation signal is provided to the radiation dosimeter via an enclosed optical path for interacting with the radiation sensitive medium. During irradiation, the optical interrogation signal is transformed into an optical information signal that encodes an ionizing radiation induced change in the optical property of the radiation sensitive medium. The radiation dosimeter system then processes the optical information signal for estimating the deposited radiation dose.
