Semi-empirical model for fluorescence lines evaluation in diagnostic x-ray beams

Appl Radiat Isot. 2016 Jan:107:152-159. doi: 10.1016/j.apradiso.2015.10.018. Epub 2015 Oct 23.

Abstract

Diagnostic x-ray beams are composed of bremsstrahlung and discrete fluorescence lines. The aim of this study is the development of an efficient model for the evaluation of the fluorescence lines. The most important electron ionization models are analyzed and implemented. The model results were compared with experimental data and with other independent spectra presented in the literature. The implemented peak models allow the discrimination between direct and indirect radiation emitted from tungsten anodes. The comparison with the independent literature spectra indicated a good agreement.
