The relationship between signals and graininess on radiographs is discussed here in the following report. It has been reported so far that the signals are reproduced by Fourier inverse transform even though the spectra of signals are cut off. For this reason, it is considered that the intensity of light which is transmitted through films makes the products of the signals and the radiographic mottles. In opposition to these, however, the following could be obtained experimentally. Those products which are made by the signals are the grains of films out of the radiographic mottles, and the brightness of reproduced images is related to the size of grains.
