Claim:
1. A radiation dosimeter for measuring radiation dose at multiple points within a detection region, wherein the radiation dosimeter comprises: a radiation detector comprising a plurality of scintillating elements located within the detection region, each scintillating element configured to generate optical energy in a different region of a scintillation spectrum in response to irradiation at multiple points within the detection region, each of the plurality of scintillating elements being responsive to a same type of radiation; a single collecting light guide optically coupled to the radiation detector and configured to receive and transmit the optical energy in the different regions of the scintillation spectrum generated by the plurality of scintillating elements; a spectral filter stage optically coupled to the single collecting light guide and configured to receive and spectrally decouple the different regions of the scintillation spectrum in the transmitted optical energy; a photo-detector stage optically coupled to the spectral filter stage and configured to generate electrical signals indicative of optical energy within at least one region of the spectrally decoupled optical energy; and a computing device connected to the photo-detector stage and configured to receive and process the electrical signals to compute the measured radiation dose.
