-Mass attenuation coefficients and partial photon interactions have been calculated theoretically at incident photon energy 1 Kev to 100 GeV for garnet series of gemstones (Grosaularite (GS1), Pyrope(GS2), Spessarlite(GS3), Almandine(GS4), Uvarovite(GS5) and Androdite(GS6) using XCOM software [1]. The values of these parameters have been found to change significantly with incident photon energy and composition of the garnet series of gemstones. Half value layer (HVL) and tenth value layer (TVL) has also been calculated; whose lower value reveals the good shielding ability for gamma rays. Hence it is concluded that GS4 shows the maximum shielding effectiveness and also GS6 and GS3 seem to have good radiation shielding. It is also analyzed that our calculated mass attenuation coefficient of NBS concrete by the present method are in excellent agreement with standard values given by ANSI/ANS-6.4.3 data.

The mass attenuation coefficient μ/ρ (cm 2 /g) is a measure of the probability of interactions of photon with matter (Hubbell, 1982(Hubbell, , 1999Hubbell and Seltzer, 1995).…”

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).

“…They found that for medium-Z glasses, effective atomic number was nearly constant and equal to the mean atomic number in a wide energy range dominated by Compton scattering process. Singh et al [8][9][10][11][12] has found a good agreement between the experimental and theoretical (calculated by the WinXCom program) values of gamma-ray mass attenuation coefficient, the Photon mean free path (MFP), the effective atomic number and the effective electron density for ZnO -PbO -B 2 O 3 glasses, investigated at photon energies of 511, 662, 1173 and 1332 keV. Singh et al [13,14] carried out two respective studies on the radiation shielding properties of lead barium borate glass and bismuth lead borate glasses.…”

Abstract:The glasses studied here have been prepared by the melt quenching technique from Egyptian rice husk silica.The obtained solid glasses exhibit amorphous nature and transparency. These glasses were selected to obey the following composition, (75-x) mol % RH silica. 25mol % Na 2 O. x mol % Bi 2 O 3 , where x takes the values, 0, 5, 10, 15 and 20. It was found that, as Bi 2 O 3 was gradually increased both the density and molar volume values increased. The comparison between the experimental and empirical density and molar volume values confirm that all the studied glasses are in amorphous glassy phase. Moreover, all samples showed also good shielding properties against gamma ray radiation and neutrons. The mass attenuation coefficient of gamma ray radiation increased gradually as Bi 2 O 3 was gradually increased while the HVL values exhibit gradual decrease, and the sample that contains 20 mol % Bi 2 O 3 appeared the efficient one at low gamma ray energy (especially at 356 KeV). On the other hand "for shielding neutrons" the sample that contains 5 mol% Bi 2 O 3 appeared the best one since it exhibits the highest neutron removal cross section.
