Abstract
AUTORADIOGRAPHY is a technique which reveals the sites of radioactivity in an object by means of a photographic emulsion. The object is brought into close contact with the emulsion and after a suitable period of time the emulsion is processed by photographic development. In such a preparation the sites of radioactivity are indicated by the presence of silver grains in the emulsion. At present, regions of an autoradiograph are regarded as different if the densities of their silver grains, in terms of some attribute of the object, are different. It may be possible to use another property of the grains to show that regions are different. This property is the way the grains are distributed in clusters.
