    Abstract: PURPOSE:To reduce size and improve the efficiency of detection by coupling a scintillator in one body to the leading end part of an optical fiber in a radiation detector combined with the scintillator and the optical fiber. CONSTITUTION:A scintillator 22 is buried integrally in the leading end part of an optical fiber 21 consisting of a core 211, cladding 212 and coating 213. The radiation detector of such construction is formed by piercing a hole through selective etching of only the core of the leading end part by, for example, an aq. HF soln. by utilizing the difference in the compositions of the core 211 and cladding 212 of the fiber 21 and burying the scintillator 22 into this hole. NaI(Tl), Bi4Ge3O12, CdWO4, etc. are used as the scintillator 22, and when radiations R are made incident to the leading end part, the scintillator 22 generates light. This light is transmitted by the fiber 21 to a photodetector 23, whereby the information on dose rate, energy, counting rate, etc. relating to the radiations R is analyzed.

    Abstract: The present disclosure relates to a method for detecting incoming radiation having a plurality of differing properties including at least one of differing types, differing energies or differing incoming directions. The method involves using a scintillator structure formed from first and second dissimilar scintillator materials, where the first and second dissimilar scintillator materials emit first and second different colors of light in response to the incoming radiation. A first light detector is used for detecting light having the first color, and a second light detector is used for detecting light having the second color. A first output signal is generated in response to the detection of light having the first color, and a second output signal is generated in response to detecting light having the second color. The first and second output signals are then analyzed to determine at least one property of the incoming radiation.

    Abstract: Interstitial brachytherapy is a cancer treatment in which radioactive material is placed directly in the target tissue of the affected site using an afterloader. The accuracy of this placement is monitored in real time using a urinary catheter that locates the radioactive material according to the radiation levels measured by sensors in the walls of the urinary catheter. A scintillator that is embedded in the walls of the urinary catheter produces light when irradiated by the radioactive material. This light is proportional to the level of radiation at each location. The light produced by each scintillator is carried through optical fibers and then converted to an electrical signal that is proportional to the light and the radiation level at each location. The radioactive material is located according to the plurality of electrical signals. This location can be used as quality control feedback to the afterloader.
