Abstract
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.
Highlights
Recent advancement of nanotechnology has made nanoscience hot area of research due to their infinite number of advantageous properties
The molar volume clearly shows that the prepared glass samples structure corresponding to higher lead composition is becoming more open leading the formation of non-bridging oxygen[9]
The molar volume and density the glass samples corresponding to low lead compositions decreases due to decreases of heavy metal content
Summary
Recent advancement of nanotechnology has made nanoscience hot area of research due to their infinite number of advantageous properties. Borosilicate glasses containing lead is of great importance because it possesses desirable electrical resistivity, low melting points, high chemical stability over a wider range of concentrations[4] These glasses play vital role in wide area of research and industrial applications related to enamels, solder glasses, semiconductor microelectronics glass, ceramic cements and in nuclear waste immobilization[5]. The study of borate glass in particular, as one the major essential glass former, once it incorporated with certain amount of heavy metal such as lead oxide and zinc oxide its properties such as hardness, mechanical strength, transparency and optical properties, drastically change(4, 5) These B2O3 glasses is one of the form major glass former due to its higher bond strength, that make them promising candidate for feature shielding materials. Mean free path (MFP) is considered as the reciprocal of the linear attenuation coefficient[8]
