Abstract
Effective atomic numbers’ (Zeff) effective electron density (Nel) for human organs and tissues have been computed in the energy region of 1 keV to 100 GeV using WinXCOM. The computed data of Zeff and Nel are tabulated. The computed values are compared with previous results. The computed data of Zeff and Nel for almost all tissues (34 tissues of different human organs) in the given energy range are not available in literature and find application in radiotherapy and dosimetry.
