Abstract

Fundamental techniques employed for radiographing materials used in nuclear energy installations are described. The X- and gamma-ray energies required for radiographing a variety of materials from plastics to gold for thicknesses ranging from foils to several inches are discussed. The X-ray energies range from 10 kvp to 22 Mev; the gamma sources include cesium-137 and cobalt-60. Details of exposure for plastic, graphite, beryllium, zirconium, lead, thorium, tantalum, tungsten alloy, uranium, plutonium, and gold are given. Information on film-screen combinations and on filter protection against the autoradiographic effects is included. Some practical applications of radiography to reactor component inspections are shown.
