A different perspective to the effective atomic number (Zeff) for some boron compounds and trommel sieve waste (TSW) with a new computer program ZXCOM

In this study, the effective atomic number (Zeff)has been calculated for some boron compounds, such as concentrate colemanite, tincal, ulexite, boric acid, probertite and TSW (Trommel Sieve Waste) by means of ZXCOM at incident beam energy (E0=59.543 keV) and scattering angle (θ=35°). We present and discuss the (Zeff) obtained by Rayleigh/Compton (R/C) ratio and evaluated for the purpose of radiation shielding which contains boron compounds, which are commonly used as shield materials.

► The (Zeff) of an infinite number of compounds will be determined according to the number actually consisting of elements which correspond to an integer number at the curve of ZXCOM.
► The result of this study shows that the effective atomic number (Zeff) is closely related to the scattering angles.
► The main objective of the study is to construct a computer program, ZXCOM, to calculate the (Zeff) at compromise (E0) and (θ) for each element, compound and mixture.
