発明の名称 (英語) SCINTILLATOR AND RADIATION DOSIMETER USING SAME
発明の概要(英語) Provided are a scintillator with improved energy sensitivity dependence within the energy range of diagnostic X-rays, more specifically in the range of 40-150 kV, and a radiation dosimeter using same. Due to the scintillator comprising a photopolymer resin that contains a polymerizable monomer, a filler and a photoinitiator, energy sensitivity dependence within the range of 40-150 kV is improved. Furthermore, changes in relative sensitivity within this energy range can be reduced to 3% or less by containing an inorganic fluorescent substance such as Zn2SiO4.
従来技術、競合技術の概要(英語) BACKGROUND ART
A highly-responsive body insertable and real-time as a dosimeter, the scintillator and the optical fiber a combination of the very small dosimeter is (SOF dosimeter) have been developed. Such SOF is, using Ir-192 dose measuring device at the time of brachytherapy but developed as, application to X-ray dose measurement it is also possible.
However, for the treatment of γ diagnostic X line is relatively low compared to the ones in energy, the energy in the range of 40 kv - 150 kv tube voltage sensitivity dependence and not to be taken into account.
