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.

Apparatus and method for determining radiation dose

A method and an apparatus for examining the subsurface microstructure of a sample are provided. Radiation from a plurality of optical radiation sources travels along a first optical path. In the first optical path, a device focuses the optical radiati n from each of the optical sources into a plurality of respective focal points along the first optical path to provide substantially continuous coverage of a selected portion of the first optical path. Then, a sample on the first optical path within the selected length extending into the sample is scanned along said selected portion of the first optical path.
