Abstract

In order to produce radiographs with controlled image quality, among other factors, it is important to know and to be able to monitor any changes in the actual size of the radiation source. This article describes a simple and practical method for the determination of source sizes which can be conveniently applied in any radiographic testing shop or even in the field. The use of a microdensitometer often needed for focal spot size measurements is avoided.
