From 1963 American Society of Metals/Metals and Materials Show, Cleveland, Oct. 1963. 23rd National Convention of the Society for Nondestructive Testing. The factors which affect the attainment of optimum results in radiography are radiation source, specimen, filmscreen combination, film processing, and their mutual relationships. A general review is presented of radiographic practice and the effects of variations in the factors, at energies below 400 kvp, on radiographic contrast and sensitivity. (D.L.C.)
