Abstract

Neutron radiography (NR) for non-destructive testing (NDT) of defects in structural materials was studied. Sensitivities and resolutions for various combinations of converters and emulsion films were measured and evaluated. Some defect indicators were prepared and imaged with NR to obtain practically usable data for NDT of steels and plastics. Very fine fatigued cracks in steels were detected by using a simple image-enhance technique. In order to obtain clearer images from blurred ones, a computed resoration technique was developed.
