Neutron Activation Analysis of Inhomogeneous Large Samples

The aim of the work described in this thesis is the development of a reconstruction method for the determination of spatial element distributions using Large-Sample Neutron Activation Analysis. For a proper introduction to this field of research, first the principles of Neutron Activation Analysis are described. Secondly, Large-Sample Neutron Activation Analysis is summarized. This is followed by the scope of the thesis and an overview of its contents. Contents include: Reconstruction of element distributions in neutron activated inhomogeneous large samples, introduction, Sampling, homogeneity and representativity, Reconstruction of element distributions in neutron activated inhomogeneous large samples, 3D-modeling of the GE detector full-energy peak efficiency for measurements of the spatial radioactivity distributions, Optimisation of the LS-INAA measurement facility for scanned measurements, Detection of inhomogeneities via collimated scanning, Gamma-ray attenuation assessment, Reconstruction Algorithms for analysis of element distributions in neutron-activated inhomogeneous large samples, REDNAILS: application with prior knowledge to samples of practical interest, General discussion.Baas, Hendrik Willem is the author of 'Neutron Activation Analysis of Inhomogeneous Large Samples ', published 2004 under ISBN 9789040725289 and ISBN 9040725284.
