Quantification of gamma-ray Compton-scatter nondestructive

A method is presented for quantifying information obtained from the indicat ions of a Compton scattering nondestructive testing technique. This is achi eved by formulating a measurement model, which provides a numerical estimat e of the detector response for a given anomaly. Using the measured response function, the location of an anomaly, its size and density are obtained wi th the aid of the model. The process is demonstrated by quantifying indicat ions obtained from experimental measurements for flaws artificially created in an aluminum block. (C) 2000 Elsevier Science Ltd. All rights reserved.
