A brief history of neutron radiography is presented to set the stage for a discussion of significant neutron
radiographic developments and an assessment of future directions for neutron radiography. Specific advances are seen
in the use of modern, high dynamic range imaging methods (image plates and flat panels) and for high contrast
techniques such as phase contrast, and phase-sensitive imaging. Competition for neutron radiographic inspection may
develop as these techniques offer application prospects for X-ray methods.
