“…Manohara et al [15] have contributed to find the energy absorption buildup factors for thermoluminescent dosimetric materials and evaluated their tissue equivalence in detail. While the studies dealt with some photon interaction parameters such as effective atomic numbers in essential amino acids, fatty acids and carbohydrates have been made with success before [2,[16][17][18][19][20], there are almost no studies for energy absorption and exposure buildup factors in essential amino acids, fatty acids and carbohydrates. This prompted us to carry out this study.…”

The total and partial mass attenuation coefficients for different Maraging steel compositions have been determined by using the WinXCom and MCNP5 programs. The effective atomic number, Z eff , and effective electron number, N eff , for the studied steels have been determined via the total mass attenuation coefficients μ/ρ, the total atomic and electronic cross sections (σ a and σ e ) of the investigated steels. The shielding parameters μ/ρ, Z eff , and N eff have been calculated at the incident photon energy range of 1 keV-100 MeV. The calculated results of total and partial mass attenuation coefficients, the effective atomic number and the effective electron number by using MCNP5 program were found to be in good agreement with the theoretical results of the WinXCom program. The calculated data clarify that the different steel compositions under investigation have so far the same ability of gamma attenuation. Also, it was found that the total mass attenuation coefficients of the different investigated steels (cobalt free-Maraging steels) are comparable to the C250 standard steel (cobalt Maraging steel).

Mass attenuation coefficients, effective atomic numbers, and electron densities for semiconductor and scintillation detectors have been calculated in the photon energy range 1 keV-100 GeV. These interaction parameters have been found to vary with detector composition and the photon energy. The variation in the parameters with energy is shown graphically for all the partial photon interaction processes. The effective atomic numbers of the detector were compared with the ZXCOM program, and the results were found to be comparable. Efficiencies of semiconductor and scintillation detectors are presented in terms of effective atomic numbers. The study should be useful for comparing the detector performance in terms of gamma spectroscopy, radiation sensitivity, radiation measurement, and radiation damage. The results of the present investigation should stimulate research work for gamma spectroscopy and radiation measuring materials.
