Measured Attenuation Coefficients at Low Photon Energies (9.88-59.32 keV) for 44 Materials and Tissues

摘要: Measurements have been made of narrow-beam linear attenuation coefficients for six important human tissues using low-energy photon radiation in the range 9.88 to 59.32 keV and, at and 17.44 keV, 38 materials employed experimental physics. The study was performed assess improve accuracy dosimetric measurements which such substitute are used simulate body air. results obtained compared with calculated published elemental compositions interaction data a polynomial fitting routine. In general, good agreement between measured basic materials. However, inhomogeneities certain produced large discrepancies.
