Description

A method to measure void fraction quantitatively by neutron radiography was proposed. The method to measure the offset of the image by the brightness of the umbrer made by a neutron absorber tape placed between the neutron source and the object have already been proposed. The quatitative brightness was calculated by subtracting the image with the tape from the image without the tape. The quatitative brightness on one image line could be obtainable with this method. A simple algorism for estimating the offset by interpolation by the two or four umbrers in one image with neutron absorber grid. (author)
