Effective Atomic Numbers, Electron Densities and CT Numbers of Some Hormones of Dosimetric Interest
KC Suresh
Abstract: The Effective atomic number, electron density and CT numbers of hormones such as testosterone, methandienone, oestradiol and progesterone for partial (coherent scattering, incoherent scattering, photoelectric absorption, and pair production in the field of the atomic nucleus and in the field of the atomic electrons) and total photon interactions in the wide energy region 10-3MeV to 105MeV using WinXCOM programme. These values are found to vary with energy and composition of hormones and Zeff vary from the element with lowest Z to the highest Z present in their composition of them. The significant variation of Zeff and Electron density with photon energy is shown in the graphs. Even CT numbers are also not remaining constant with energy and it helps in visualizing the image of the biological samples.
