• In order to develop information-radiography, a definition of information volume is given with respect to the information of contrast due to test-pieces on an object having a wide thickness-range. Among the density-to-exposure curves which passes the same end-points, the linear one has maximum information. A contrast-deficient radiograph has more information than an excessively contrasted radiograph, since the former represents the entire thickness-range. The information volumes thus defined gives radiographic effects due to the combination of equipment, exposure-factors, and objects. Some numerical examples are included.
