WebOct 1, 2016 · The variation in dosimetric parameters such as mass attenuation coefficient, half value layer factor, exposure buildup factor, and the photon mean free path for different oxide glasses for the incident gamma energy range 0.015–15 MeV has been studied using MicroShield code.It has been inferred that the addition of PbO and Bi 2 O 3 improves the … WebFigure 12 shows variation of energy absorption buildup factor (EABF) and exposure buildup factor (EBF) against effective atomic number (Z eff) at 1 MeV and 5 mfp for all glasses. It can be clearly seen from Figure 12 that the EBF and EABF is higher for glasses with high Z eff than for glasses with low atomic Z eff .

WebDec 14, 2024 · The buildup factor is a correction factor that considers the influence of the scattered radiation plus any secondary particles in the medium during shielding calculations. If we want to account for the buildup of secondary radiation, then we have to include the buildup factor. WebNew work has been done on buildup factors since then. In 1991, the numbers indicate that at low energies the buildup factor is 1 or close to it. New studies and new calculations indicate that it is not so. A paper published in 2001, “Low and High energy factors for selected materials updated with Monte Carlo code factors”: Chibani, Omar, 2000.
