Mr. Masaki Ishida, Engineer at the Radiation Science Center, received the Outstanding Poster Award at the 20th Ibaraki Analytical Technology Workshop

Mr. Masaki Ishida, Engineer at the Radiation Science Center, received the Outstanding Poster Award at the 20th Ibaraki Analytical Technology Workshop held on November 6, 2026. The title of the award-winning presentation was “Non-Destructive Identification of Washi Materials by Infrared Spectroscopy: A Comparative Study of ATR and Reflectance Measurement Methods.”
The Environmental Measurement Group of the Radiation Science Center has been conducting a collaborative research project with the Historiographical Institute of the University of Tokyo since FY2022. The project focuses on the non-destructive identification of washi materials, including source plants and additives, for applications to paper-based cultural heritage objects.
In this presentation, Mr. Ishida reported on an FT-IR analysis using a reflectance measurement unit (ConservatIR, Thermo Fisher Scientific), which improved both material discrimination and non-destructive analysis of washi samples.
