<p>A dosimetry method and associated apparatus characterized by the steps of storing information in a three-dimensional optical memory element (20), then exposing the optical memory element to neutron or other high LET radiation to alter the information stored in the optical memory element as a function of the radiation to which the optical memory element is exposed, and then retrieving the altered information from the optical memory element. In a preferred embodiment, subsequent analysis of the altered information uses a neural network computer apparatus (30). The altered information is used to provide a measure of both the radiation dose and energy. The optical memory may be a 3-D ORAM (20) with a volume of a transparent polymer doped with a light sensitive chemical and, in particular, spirobenzopyran. Also, a spectrometer (40) for monitoring neutron and other types of radiation, an electronic dosimeter (50) for providing real-time monitoring of radiation exposure, and associated methodologies, are all based on use of an optical memory element.</p> |
