“…4 shows that the values of HVL for the present G1-G6 glasses increased with the increments in the incident photon energy. It is found that the HVL thickness is the lowest for G6 glass system with ρ=6.22 g/cm 3 and the highest for G1 glass system with ρ=5.82 g/cm 3 . It can be easily expressed that the HVL values reduces with the increase of density; hence the shielding superiority increases with the density of the material.…”

“…In order to determine the characteristic of the selected glass systems and the possibility of development as a promising shielding material, it is required to compare the radiation shielding performance with previously published various materials (such as concretes, glasses [42]. The obtained HVLs have lower than all concretes (C1-C7) and glasses (S1-S7) while they are higher than those of Gl4, Gl5 and Gl6 glass samples having densities of 7.726, 7.801 and 8.284 g/cm 3 , respectively [39]. Furthermore, the present results are a rather similar as those of Gl2 and Gl3 glass types.…”

“…There are three parameters to attenuate intensity of gamma-rays: exposure time, distance from the source and shielding. Among these parameters, the most relevant technique on protection from nuclear radiation has been provided by shielding with a material of convenient thickness [1][2][3]. Therefore, the option of improvement and production of different content materials as preventive shielding for ionizing radiation has been of great interest.…”

In the present study, the gamma radiation shielding properties of glasses in CdO-WO 3 -TeO 2 ternary systems have been calculated using WinXCom program. The mass attenuation coefficient ( ), half value layer (HVL), effective atomic number (Z eff ) and electron density (N eff ) values for total photon interaction for a wide range of photon energies from 0.015 to 10 MeV have been estimated. The obtained results for the investigated glass systems have been compared in terms of HVL with some standard concrete and different glass samples in order to validate these glasses in point of the radiation shielding. Among the present glasses, G6 glass sample has the best shielding capability against gamma radiation.

“…Roughly speaking, photons and particles with energies above about 10 electron volts (eV) are ionizing (some authorities use 33 eV, the ionization energy for water). Particle radiation from radioactive material or cosmic rays almost invariably carries enough energy to be ionizing [5].…”

Radiation is the emission or transmission of energy as waves or particles through space or through a material medium which is able to penetrate various materials and is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Radiation processing can be defined as exposure of materials with high energy radiation to change their physical, chemical, or biological characteristics, to increase their usefulness, and safety purpose, or to reduce their harmful impact on the environment. Ionizing radiation is produced by radioactive decay, nuclear fission, and fusion, by extremely hot objects, and by particle accelerators. The radiation coming from the sun is due to the nuclear fusion; therefore, we are living in a natural radioactive world. Radioactive substances are common sources of ionized radiation that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Alpha rays are the weakest form of radiation and can be stopped by paper. Beta rays are able to pass through paper but not through aluminum. Gamma rays are the strongest radiation. They are able to pass through paper and aluminum, but not through a thick block of lead or concrete. Alpha and beta radiation are the high energy subatomic particles where gamma radiation is a form of high energy electromagnetic waves. This review presents the fundamental introduction of radiation, the three types of radiation, and their applications.

“…Various Turkish granites and marble spices were investigated via measuring (µ), (µ/ρ) the half value layer and the tenth value layer, at the energy region 80.99 keV to 1.332 MeV using HPGe detector, the results were compared with literature. [10] The density of hydrous peridotite magma containing 5% wt. H2O was measured at pressures and temperatures up to 4.3 GPa and 2073-degree K, respectively, using the X-ray absorption method.…”

Using a γ-ray spectrometer with 3"x3" NaI (Tl) detector the linear and mass attenuation coefficients (µ/ρ) and (µ b /ρ) from narrow and broad beam experimental arrangements have been measured and compared with the theoretical values for the granites Double Black, DB, from India, Rose Al-Howdy, RH, from Aswan, south Egypt and Bianco Halayeb, BK, from Halayeb, south Egypt. The photon energies lei in the range 0.081-1.332 MeV from the radioisotopes 133 Ba, 137 Cs and 60 Co. The build-up factor B, the effective atomic number Z eff , and the total atomic cross-section σ t for the granites as a function of photon energy were determined and discussed. It is found that the experimental results are consistent, within the experimental errors, with the theoretical values. The effective atomic number Z eff , the build-up factor B, and the total atomic cross-section σ t were calculated and discussed as a function of photon energy. The B factor is large at low gamma energy and not sensitive for discrimination between the granites. The maximum Z eff corresponds to minimum B factor at the photon energy 0.356 MeV. The broad beam geometry is more efficient than narrow beam geometry in characterizing the shielding properties of the studied granites.
