Abstract
Method for determining the average density or volume percentage of at least one coarse grained component of a multicomponent mixture by gamma transmission analysis, including the steps of irradiating the mixture with gamma radiation from at least one source, detecting the transmitted radiation by means of at least one detector, and evaluating the relation between the transmitted and detected radiation to determine the average density or volume percentage by using a transmission equation applicable to homogeneous mixtures, the evaluation including transforming the values resulting from solving such equation, or a selected term of such equation, with the aid of a correction function which is derived by comparison of corresponding values in the transmission equation applicable to the homogeneous mixtures and in a further transmission equation which is dependent on the particle sizes of the coarse grained component in order to provide a corrected determination relative to that component.
