“…This is most evident in the borate system where there are fairly large differences between the calculated and measured values, most notably, there are a group of borate data points that have calculated index of refraction values that are much higher than the experimental values. 55,59 This is in contrast with the other glasses measured at the sodium D line, which show that the calculated index of refraction value is generally less than the experimental one, such as the other boron-containing glasses (borosilicate and boroaluminates).…”

“…9,55 It should also be noted that both Ramesh et al and Divina et al used porcelain crucibles to melt their glasses for long periods of time ≥30 min. 55,59 It is well known that the crucible type that a glass is melted in is very important. For instance, if a borate glass is melted in an alumina crucible, it will tend to leach alumina from the crucible, which will then incorporate into the glass.…”

The Gladstone–Dale relation is among one of the many formulae put forward in the 19th century to try and relate the index of refraction and density of a material. Compared to other relations of the time, the Gladstone–Dale relation is advantageous as it is relatively simple to use. It has been suggested that the Gladstone–Dale relation can be used as a reliable way to calculate the index of refraction for oxide glasses because of the additive nature of the relation, making it ideal for glass compositions. The reliability of the Gladstone–Dale relation with regards to its use in glass science has been explored. Various oxide glass systems that use different network formers, conditional network formers, modifying oxides, and dopants have been obtained from the literature to determine the reliability of the relation with regards to index‐of‐refraction calculations. The benefits and faults of the relation are discussed, and it was found that it is not universally applicable for all glass compositions.

“…when the TeO2 content changes from 0 up to 40 % mol for all glasses, the calculated mass attenuation coefficient showed an increasing behavior principally at an energy value 0.356 MeV, 4TBS glass material displayed the lowest value of half-value layer. The study assures that the alteration of B2O3 by TeO2 supports the capability of the prepared glassy materials to minimize the gamma photons [15]. Furthermore, TL dosimetric properties for rare-earth-doped tellurite form glasses were examined [13].…”

Magnesium silicate has been prepared by a precipitation technique. This composite structure was proven by different tools, XRD, TGA&DTA, FTIR, and XRF. Magnesium silicate was found to have the formulas Mg1.1SiO3.2.1.1H2O. Thermoluminescence (TL) dosimetric properties like (linearity, fading, energy independence) of magnesium silicate in the shape of MgSiO3 have been estimated. A strong TL dosimetry peak associated with gamma radiation arises from 137 Cs was developed. Different doses from gamma radiation were measured by thermoluminescence (TL) detection technique for magnesium silicate glasses in unique magnesium elements concentration to assess its dosimetric properties. A single strong peak of about 230 °C arises for all irradiated samples. Total integral values of TL output and TL of the principal peak values showing a linear behavior start with 0.5 Gray up to 2 Gray dose range. Correlation of magnesium silicate TL response and different doses showed dose-response improvement concerning low doses linear relationship.

“…This procedure was extended for the epoxy composites of different compositions of varying thickness (0.095 to 2.956 g cm −2 ) and the μ/ρ values were determined. Other γ-ray interaction parameters such as half value layer (HVL in cm), tenth value layer (TVL in cm), and relaxation length (λ in cm) were also determined using Equations (5,6,7).…”

Epoxy resin filled with suitable high Z elements can be a potential shield for X‐rays and γ‐rays. In this work, we present the γ‐ray attenuation properties of epoxy composites filled with (0–30 wt%) Tantalum pentoxide (Ta2O5) and Ta2O5‐Bi2O3, which were prepared by open mold cast technique. X‐ray diffraction patterns showed crystalline peaks of Ta2O5 and bismuth oxide (Bi2O3) in the prepared epoxy‐Ta2O5 and epoxy‐Ta2O5‐Bi2O3 composites. Homogeneity of the samples at higher filler wt% was revealed by SEM images. Mechanical characterization showed the enhanced mechanical strength of epoxy‐Ta2O5‐Bi2O3 composites compared to epoxy‐Ta2O5. Higher storage modulus and glass transition temperature of the epoxy‐Ta2O5‐Bi2O3 composites showed enhanced stiffness and thermal stability when compared to neat and epoxy‐Ta2O5. Decrease in the value of tan(δ) at higher content of filler loadings indicated the good adhesion between filler and matrix. Mass attenuation coefficients of epoxy‐Ta2O5 (30 wt%) composites at γ‐ray energies 59.54 and 662 keV were found to be 0.876 cm2 g–1 and 0.084 cm2 g–1, while that of epoxy‐Ta2O5‐Bi2O3 (30 wt% Bi2O3) composite were 1.271 cm2 g–1 and 0.088 cm2 g–1, respectively. The epoxy‐5% Ta2O5‐30% Bi2O3 composites with higher μ/ρ value and tensile strength may be a potential γ‐ray shield in various radiation environments.
