Experimental studies on measurements of mass attenuation coefficients of boric acid at different concentration

Abstract

Measurements have been made to determine variation of the mass attenuation coefficients of H3BO3 according to percentage increasing concentration of H3BO3 by using an extremely narrow-collimated-beam transmission method in the energy range 15.746-40.930 keV with an X-ray transmission method. The characteristic K-alpha and K-beta X-rays of the different elements (Zr, Mo, Ag, In, Sb, Ba and Pr) passed through boric acid was detected with a high-resolution Si(Li) detector. Results are presented and discussed in this paper. (C) 2003 Elsevier Ltd. All rights reserved.
