Study of Mass Attenuation Coefficients of Some Human Tissues Using X-Com
(Addis Ababa University, 2021-10-04) Abajihad, Mohammed; Tesfaye, Tilahun (PhD)
Themass attenuation coefficient of some tissues such as muscle(ICRU),adipose(ICRP) andblood(whole) and tissue equivalents such as soft tissue model (H63C6O28N) And water were investigated theoretically at different photon energies using XCOM computer program (version3.1) in the energy range of 1keV-2MeV.Specifically,the mass attenuation coefficients obtained theoretically (XCOM computed coefficients )were compared with experimental results for 59.5, 81.0, 356.5, 661.6, 1173.2 and 1332.5keV photon energies. The mass attenuation coefficient the XCOM computed were compared totheexperimentalvalues,between the two with uncertainties about 5% that is the XCOM program is essential in the calculation of photon mass attenuation coefficient of some human tissues as the other found in literature.
