ABSTRACT:
A beam of X rays is directed into a traveling product such as paper having a constituent such as ash made up of components such as clay, chalk and titanium dioxide.
X rays from the product may produce signal channel responses that are the same to one component but different to another component, and a resultant response indicative of the content of the constituent or component.
The X rays from the product may produce a response to a detected spectrum wherein the intensities of the rays are so distributed as a function of energy that the average effective absorption coefficients for the components are substantially equalized, so that the response will be indicative of the constituent and comparatively unaffected by the relative amounts of the components.
