A METHOD FOR QUANTITATIVE MEASUREMENT BY THERMAL NEUTRON RADIOGRAPHY
Source abstract
Abstract
Abstract A quantitative measurement method by thermal neutron radiography was proposed for two-dimensional void fraction measurement in two-phase flow. The umbra method was modified for two-dimensional measurement by using a neutron absorber grid. Image processing methods to compensate for the effects of neutrons scattered in the object and optical rays scattered in camera were developed. A step made from acrylic resin was tested with a B4C grid 3mm in width and 3mm in interval. It was shown that two dimensional quantitative measurement was possible with this method in sacrifice of the spatial resolution. keywords: Neutron radiographyQuantitative measurementUmbra methodScattering
