“…Therefore, any type of material can be used for radiation shielding once it has capability to absorb the incident radiation to a certain level. In the area shielding material and propose same research works with different glass as new shielding material [11]. In the light of above discussion, the author in the present paper has shown interest in the borate glass system containing oxides of boron, zinc and lead.…”

“…At low mole fractions the role of metal oxide is of network modifier and at higher mole fractions the role changes to network former. [10,11] Further mass attenuation coefficients are given in table 2. A large attenuation coefficient means that the beam is quickly "attenuated" as it passes through the medium, and a small attenuation coefficient means that the medium is relatively transparent to the beam.…”

Some borate-based systems doped with sodium, zinc and lead are chosen to study gamma ray mass attenuation properties. Different parameters like mass attenuation, half value layer and mean free path have been analyzed at different photon energies. The values of molar volume have been estimated from density values to get idea regarding the compactness of the network structure. XCOM computer software has been employed to estimate mass attenuation coefficient at various energies. Further the values of HVL for the studied systems are compared with standard radiation shielding materials like concrete.

“…From Table 2 it can be concluded that sample S4 has the lowest mean free path at high energy, which means the rate at which the photon energy is penetrating the sample is less in samples S4. Furthermore, the values of mean free path increase with the increase in the energy of incident Photon 12 .…”

Gamma ray shielding properties of borate glass samples containing oxides of lead and zinc are prepared by melt and quench technique and evaluated theoretically using XCOM computer software for gamma ray shielding properties. However, gamma ray shielding properties are discussed in terms of various calculated parameters such as half value layer, mean free path and mass attenuation coefficient. The calculated parameters are compared by the author with conventional shielding material concrete. FTIR studies are undertaken to investigate the various structural groups present in the prepared system. Furthermore, it was observed that the glass sample S1 posses minimum HVL value and maximum mass attenuation coefficient, It has been inferred that addition of lead improve the gamma ray shielding properties and simultaneously decrease the rigidity of the glass systems due to formation of non bridging oxygen. Gamma ray shielding properties of our glass systems have been compared with standard nuclear radiation shielding concrete.

“…So, it is of interest to search for suitable shielding materials that can be used to protect mankind from hazard radiation, specially the contact users. Accordingly, many articles have been published aiming to investigate various types of glasses for such problem [1][2][3]. This is because, glasses are considered to be preferable shielding materials than those classically used, since glasses can be easily manufactured and shaped, in addition to their ability to transmit visible light and deprived toxicity [4].…”

These glasses can have many interesting applications especially as gamma ray attenuators.The amorphous nature and the glassy state character of these glasses can be confirmed from comparing the experimental and empirical values of both their density and molar volume. It was found that, as SrO was gradually increased the density increased while the molar volume decreased which may be due to the gradual decrease of the number of oxygen ion density in the glass networks.The micro-hardness and magnetic susceptibility are also increased, which can be attributed to the gradual migration of iron from glass network modifier (GNM) to glass network former (GNF) positions, as confirmed by IR and ME results. IR and ME analysis indicated that both ferric and ferrous have tetrahedral and octahedral symmetry respectively and acting as GNF and GNM at different SrO contents. The gradual replacement of P2O5 by SrO force the iron to transfer from GNM to GNF.The gamma-ray mass attenuation coefficient increased with the gradual increase of Sr 2+ as heavy metal, while the HVL decreased. On the other hand the attenuation coefficient decreased with the increase of gamma-ray photon energy. So, these glasses can be used as transparent shielding materials for low gamma-ray energies and to capsulate the radioactive wastes, while the sample containing 15 mol% SrO, exhibits the highest attenuation coefficient.
