摘要： A radiation or neutron detector wherein lateral side light detecting optical fibers prepared from clear optical fibers that are scraped on a lateral side to permit side incidence of fluorescence are used to detect the fluorescence from a phosphor or a scintillator such that the background to gamma-rays is reduced. If desired, the optical fibers may be bent at 90 degrees and guided to a photomultiplier tube in order to reduce the size of the detector. Fabrication and maintenance of the detector can be facilitated by adopting such a design that a detecting block comprising a detection medium and lateral side light detecting optical fibers is separated from a readout block comprising clear optical fibers.

摘要： Systems and methods for the simultaneous detection and identification of radiation species, including neutrons, gammas/x-rays and minimum ionizing particles (MIPs). A plurality of rectangular and/or triangularly shaped radiation sensitive scintillators can be configured from a plurality of nano-sized particles, dopants and an extruded plastic material. A wavelength-shifting fiber can then be located within a central hole of each extruded scintillator, wherein the wavelength-shifting fiber absorbs scintillation light and re-emits the light at a longer wavelength, thereby piping the light to a photodetector whose response to the light indicates the presence of radiation The resulting method and system can simultaneously detect neutrons, gamma rays, x-rays and cosmic rays (MIPs) and identify each.
