Abstract

The single scattering model for gamma backscatter density gauges has been extended to describe how the total detected count rate changes in response to localised density variations within the material. This extended model suggests there is a spatial region where density perturbations have a contradictory effect on the measured density value, an effect that has already been shown experimentally by previous workers. Here we compare their results with those predicted by application of the extended single scattering model. Since a complete description of their experimental apparatus was not available, only a crude fit could be achieved. Nevertheless, all the basic features of the data could be reproduced.
