“…Also various researcher have studied gamma ray buildup factors of different types of materials such as amino acids, fatty acids and carbohydrates (21), polymers (22), Heavy metal oxide glass (23), which showed that the GP fitting is a very useful method for estimation of exposure and energy absorption build-up factors.…”

ABSTRACT:To check the feasibility of the use of Dana's minerals such as Analcime (M1), Chabazite (M2), Heulandites (M3), Pyrophyllite (M4), Scapolite (M5), Stilbite (M6) and Serpentine (M7) as gamma ray shielding materials, some parameters of dosimetric interest has been investigated at incident photon energies from 15 keV to 15 MeV and penetration depth upto 40 mfp.The photon interaction with minerals has been discussed mainly in terms of Mass attenuation coefficient (µ m ), Equivalent atomic number(Z eq .) and exposure buildup factors (EBF). The results have been shown graphically with more useful conclusions. From the present investigations, it has been concluded that among the selected minerals, M2 and M5are the best gamma ray shielding material, due to its higher values of mass attenuation coefficient and least values for exposure buildup factor in the selected energy range.

“…Thus, firstly the Compton partial mass attenuation coefficient, (µ/ρ) Compton , and the total mass attenuation coefficients, (µ/ρ) Total , were obtained for the elements of Z= 4-40 and for the soils and ceramic materials in the energy region 0.015-15 MeV, using the XCOM [18] computer program. For the interpolation of Z eq for which the ratio (µ/ρ) compton /(µ/ρ) Total lies between two successive ratios of elements, the following formula has been employed [16]:…”

“…Buildup factors, on the other hand, can be obtained from existing tables, developed by the American Nuclear Society. Since these tables are not applicable for a general case, they should be adopted for given kinds of measurements [3,4]. Buildup factor is important for proper gamma attenuation measurement and can affect the measurement quality [5].…”

Gamma ray measurement is an important issue in nuclear technology, since it is widely used in industry, medicine, agriculture, education research, and some military applications. Gamma ray is also needed to build radiation protection, which is very useful for human health. When gamma radiation penetrates through shielding material, it generates two radiation components within or beyond the shield, namely: the uncollided and the collided photons. Therefore, the buildup factor is an important parameter for gamma ray measurement. Buildup factor is defined as the ratio of the total number of particles at a given point to the number of uncollided particles, at that same point. In this work, we evaluate the gamma-ray buildup factors for copper , as a function of energy, for 0.511, 0.662, 1.275 MeV, by using cesium and sodium radioactive sources. The results show that the value of energy buildup factor decreases with increasing gamma energy, and increases with increasing thickness. Moreover, it was found that at high energies (1.275 MeV), the absorption buildup factor is at minimum when the energy is at high level. The results also reveal that there is no contribution from the scattering photons to the value of buildup factor, in general, at low intensity levels, when the geometry structure is built well. While for bad geometry, the detector measures intensity, which is greater than that described by the main linear attenuation coefficient, because the scattered photons will be detected as well. All in all, in order to get rational results, a well geometry should be used for the future applications.
