Quantification of gamma-ray Compton-scatter nondestructive testing

A method is presented for quantifying information obtained from the indications of a Compton scattering nondestructive testing technique. This is achieved by formulating a measurement model, which provides a numerical estimate of the detector response for a given anomaly. Using the measured response function, the location of an anomaly, its size and density are obtained with the aid of the model. The process is demonstrated by quantifying indications obtained from experimental measurements for flaws artificially created in an aluminum block.
