    • PROBLEM TO BE SOLVED: To provide a neutron imaging plate with a low γ-ray sensitivity.
      SOLUTION: A powder obtained by uniformly mixing a fluorescent powder of BaFBr:Eu
      2+ and a boric acid (H
      3
      10 BO
      3 ) powder with a
      10 B isotope composition ratio of 90% is applied on a metal substrate and sintered. Defects are thermally diffused and introduced to the surface of the fluorescent powder of BaFBr:Eu
      2+ to obtain a surface sensitive stimulable phosphor. The inhibiting capacity of an α particle and an
      7 Li particle emitted when
      10 B capatures a neutron is greater than the inhibiting capacity of an electron emitted by the γ beam functioning as a back ground is used to lower the sensitivity to the γ beam. Thus, the imaging plate with desensitized γ-beam sensitivity is obtained.

    • The characteristics of the phosphor ZnS:Ag,Cl which has a considerably high fluorescence yield in response to incident particles thus allowing for their easy detection are used as such and combined with the finding that the fluorescence components in the range of shorter wavelengths are short-lived, which led to an improvement of counting characteristics, hence allowing for high-rate measurements of particles. When B370 was used as an optical filter to pick up fluorescence components shorter than 450 nm, the decay time of short-lived fluorescence components could be reduced from 370 ns to 200 ns.
    • 因此,使用荧光体ZnS:Ag,Cl的响应于入射粒子具有相当高的荧光产率,从而允许其容易检测的特征,并结合发现在较短波长范围内的荧光成分短, 生活,这导致计数特性的改善,从而允许高速率的粒子测量。 当B370用作光学滤光片以吸收小于450nm的荧光成分时,短寿命荧光成分的衰变时间可以从370ns降低到200ns。

    • The present invention is directed to a nuclide separation precipitator system in which noble gas nuclear fission products are introduced into a gas reservoir and generate charged daughter nuclides in the gas reservoir. A collector collects three detectable charged daughter nuclides. A detector detects the energy distributions of beta-rays and gamma-rays emitted from the daughter nuclides collected in the collector and outputs signals indicative of the detected beta-rays and gamma-rays. Three pulse height discriminators discriminate the signals output from the detector into three respective energy levels of a low energy range, a middle energy range, and a high energy range. A first order simultaneous equation of three unknowns obtained by utilizing a fact that counting ratios of the three energy ranges vary for each daughter nuclide is then solved.

    • A neutron detector with a unique neutron detecting element is disclosed. The neutron detecting element has an inner cylindrical neutron scintillator where a neutron detection body including a ZnS phosphor, and a neutron converter material which contains 6Li or 10B is arranged outside of the cylindrical substrate; a scintillator fluorescence detection body made by placing coiled wavelength shift fibers where two wavelength shift fibers are wound in parallel along the cylindrical substrate on said inner cylindrical neutron scintillator; and an outer cylindrical neutron scintillator where a neutron detection body is arranged inside of the cylindrical substrate, the outer cylindrical neutron scintillator being arranged on the scintillator fluorescence detection body. The fluorescence signals converted into pulse signals by two optical detectors are led to a coincidence circuit, and when two fluorescence signals are measured simultaneously during the predetermined period of time, a neutron signal is output.

    • 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.
