    摘要: Various embodiments are described herein for a radiation dosimetry apparatus and associated methods for measuring radiation dose. In some embodiments, the apparatus includes multiple scintillating elements for detecting amounts of radiation dose at multiple points within a detection region. Each of the scintillating elements generates light in response to radiation interacting within their volume. A light guide combines the light generated by all of the scintillating elements as well as radiation-induced contaminated optical energy and transmits the combined light to a spectral analysis setup. Multi or hyper-spectral calibration technique allows calculating the dose or dose rate at the positions of the different scintillating elements. The calibration technique isolates the light produced by a given scintillating element from the other scintillating elements as well as any other source of radiation-induced contaminating light.

    摘要: A radiation dosimetry apparatus and method use a scintillating optical fiber array for detecting dose levels. The scintillating optical fiber detectors generate optical energy in response to a predetermined type of radiation, and are coupled to collection optical fibers that transmit the optical energy to a photo-detector for conversion to an electrical signal. The detectors may be embedded in one or more modular, water-equivalent phantom slabs. A repeatable connector couples the collection fibers to the photo-detector, maintaining the fiber ends in a predetermined spatial relationship. The detector fibers may be distributed as desired in a three-dimensional detection space, and may be oriented with their longitudinal axes at different orientations relative to a transmission axis of an incident radiation beam. A calibration method uses two measurements in two spectral windows, one with irradiation of the scintillator at a known dose and one with only irradiation of the collection fiber.
