    NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION B-BEAM INTERACTIONS WITH MATERIALS AND ATOMS   263 ( 1 ) 58 - 62  2007.10  [Refereed]

     View Summary

    This paper describes a direction finding gamma-ray detector, which consists of three different scintillators; NaI (Tl), CsI (Tl) and BGO. The detector positively increases directional sensitivity to incident gamma-rays, and can measure direction, energy and number of gamma-rays. This detector will be useful to carry out monitoring of nuclear power plants or radiation facilities in emergencies. It will be also effective in searching for radiation sources such as radioisotopes and radioactive contaminations. Experimental results have shown the proposed directional detector has a potential for practical use in real fields and will contribute to radiation emergency preparedness. (C) 2007 Elsevier B.V.

    NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION B-BEAM INTERACTIONS WITH MATERIALS AND ATOMS   213 ( 213 ) 255 - 259  2004.01  [Refereed]

     View Summary

    This paper describes directional gamma ray detectors with different types of scintillators. The detectors, which positively increase directional sensitivity to incident gamma rays, have been developed to measure directions, energies and counts of gamma rays, and to search for radioactive materials such as orphan radioisotopes or contaminations. Experimental results have shown that proposed directional detectors have a potential for practical use in real fields and will contribute to radiation protection and safety. (C) 2003 Elsevier B.V.

  • A build-up treatment for thickness gauging of steel plates based on gamma-ray transmission

    Y Shirakawa

    APPLIED RADIATION AND ISOTOPES   53 ( 4-5 ) 581 - 586  2000.10  [Refereed]

     View Summary

    A thickness gauging model of steel plates with build-up treatment, which is based on a gamma-ray transmission technique, has been proposed. Its performance has been evaluated by experiments using the real Cs-137 thickness gauge equipped at the heavy plate mill in the steel industry. It is shown that the calculated values with the new model are in good agreement with experimental data obtained by the gamma-ray thickness gauge in the thickness range from 0 to 10 cm.
