The introduction of x-ray paper for the radiographic control of Materials Testing Reactor fuel was preceded by an investigation of the sensitometric properties of Kodak and Agfa-Gevaert paper at 45 and 150 kV. Radiographic quality of aluminum, steel, and uranium/aluminum block and uranium/aluminum plate radiographs showed that the x-ray paper has adequate quality (image quality indicator sensitivity better than 2%) and therefore can be used instead of x-ray film, which is more expensive and requires longer exposure and processing time.
