Effect of Bi2O3/WO3 on Improving the Ability of Polyepoxide-Based Composites to Attenuate Gamma Rays

This work aims to prepare a new series of polyepoxide resins reinforced with a mixture of WO3 and Bi2O3 compounds. The effect of replacing WO3 with by Bi2O3 on the radiation shielding parameters was experimentally evaluated using a NaI (Tl) detector and many radioactive sources, including 22Na, 133Ba, 137Cs, 60Co, and 152Eu. The linear attenuation coefficient for the prepared new polyepoxide-based composites was improved when substituting increasing amounts of WO3 with Bi2O3. When increased from 2.164 to 2.943 cm−1 (at 33 keV) and from 0.073 to 0.104 cm−1 (at 1332 keV), the Bi2O3 concentration in the prepared composites varied from 0 to 10 wt%, respectively. The substitution of WO3 with Bi2O3 greatly improved the shielding parameters of the fabricated composites. The half-value thickness, transmission factor, and lead-equivalent thickness were observed to decrease with increasing concentrations of Bi2O3 in the fabricated composites.

Comparison of shielding effects of over-glasses-type and regular eyewear in terms of occupational eye dose reduction

Given the new recommendations for occupational eye lens doses, various lead glasses have been used to reduce irradiation of interventional radiologists. However, the protection afforded by lead glasses over prescription glasses (thus over-glasses-type eyewear) has not been considered in detail. We used a phantom to compare the protective effects of such eyewear and regular eyewear of 0.07 mm lead-equivalent thickness. The shielding rates behind the eyewear and on the surface of the left eye of an anthropomorphic phantom were calculated. The left eye of the phantom was irradiated at various angles and the shielding effects were evaluated. We measured the radiation dose to the left side of the phantom using RPLDs attached to the left eye and to the surface/back of the left eyewear. Over-glasses-type eyewear afforded good protection against x-rays from the left and below; the average shielding rates on the surface of the left eye ranged from 0.70–0.72. In clinical settings, scattered radiation is incident on physicians’ eyes from the left and below, and through any gap in lead glasses. Over-glasses-type eyewear afforded better protection than regular eyewear of the same lead-equivalent thickness at the irradiation angles of concern in clinical settings. Although clinical evaluation is needed, we suggest over-glasses-type Pb eyewear even for physicians who do not wear prescription glasses.

Comparative analysis of TiO2, Fe2O3, CaO and CuO in borate based glasses for gamma ray shielding

This research intends to utilize melt-quenching technique in order to examine the radiation shielding capability of 10 % Mo, 10 % Na2O, 20 % PbO, and 60 % B2O3 glass system, with varying CaO, TiO2, CuO, Fe2O3 or Mo. XCOM and MCNP simulations were utilized to analyze the radiation shielding properties of the fabricated glasses. The results revealed CuO having the superior MAC of 49.91 cm2/g, then Fe2O3 with 49.24 cm2/g, followed by CaO with 49.10 cm2/g, and TiO2 with 48.49 cm2/g as the least. CuO and Fe2O3 were confirmed to have least HVL compared to CaO and TiO2. The value of the lead equivalent thickness showed fluctuation against the gamma energy, where it raisess within the photoelectric region and falls after the photoelectric region. The data reveal that, the lead equivalent thickness at 0.1 MeV were 7.88 cm, 7.86 cm, 7.81 cm and 7.80 cm for TiO2, Fe2O3, CaO, and CuO in the same order, respectively. The transmission factor (TF) raises as the gamma energy raises, having TiO2 as the highest with 76.068 %, while the radiation protection efficiency dropped as the energy raises.

Detailed investigations for mechanical and gamma-ray attenuation characteristics of B2O3-ZnO-BaO-TiO2 glasses doped with PbO

The effect of PbO addition with different concentrations on four synthesized zinc titanium borate glasses with the chemical formula xPbO-(75-x) B2O3-10ZnO-10BaO-5TiO2 (x = 30, 35, 40, and 45 mol%) was explored in this study. The partial PbO substitution for B2O3 increases the fabricated glasses' density by ≈ 20% from 5.31 to 6.37 g/cm3, respectively, with raising the PbO concentrations between 30 and 45 mol.%, respectively. Besides, the substitution mentioned above enhances the gamma-ray attenuation properties where the linear attenuation coefficient increased between 69.911 and 102.245 cm−1 (at 0.033 MeV), 0.341–0.415 cm−1 (at 1 MeV), and 0.200–0.262 cm−1 (at 10 MeV), increasing the PbO concentration between 30 and 45 mol.%, respectively. Simultaneously, increases in the PbO concentration within the fabricated glasses decrease the lead's equivalent thickness between 3.82 and 2.61 cm (at 0.033 MeV), 2.35–1.93 cm (at 1 MeV), and 2.81–2.14 cm (at 10 MeV). In contrast, substituting PbO for B2O3 compounds diminishes the fabricated glasses' mechanical properties, where the microhardness decreased by 13.5 % from 4.24 to 3.67 GPa. The lead equivalent thickness (Deq) values at 0.66 MeV were found equal to 2.410, 2.232, 2.078, and 1.945 cm, and at 1.112 MeV, these values were found equal to 2.222, 2.081, 1.956, and 1.829 cm for G1, G2, G3, and G4, respectively.

Extensive analysis of several Indian and Yemeni soils' gamma-ray shielding characteristics: An experimental and simulation approach

The linear attenuation coefficients (LAC) of four soils (Black cotton (S1), Sandy (S2), Clay (S3), and Sandy (S4)) samples were measured at photon energies released from radioisotopes Co57 (122 keV), Ba133 (356 keV), 22Na (511 and 1275 keV), Cs137 (662 keV), Mn54 (840 keV), and Co60 (1330 keV) using a gamma spectrometer includes a NaI (Tl) scintillation detector. The experimental measurements were confirmed utilizing the Monte Carlo N-particle transport code. The linear attenuation coefficient values enhanced from 0.256 cm−1 to 0.296 cm−1 (at Eγ of 122 keV), from 0.126 cm−1 to 0.142 cm−1 (at Eγ of 662 keV), and from 0.0938 cm−1 to 0.105 cm−1 (at Eγ of 1275 keV), raising the (Fe + Mn) concentration from 0.912 wt% to 11.214 wt%, as well as raising the soil samples density from 1.62 g/cm3 to 1.79 g/cm3. The study also shows an enhancement in the half value thickness, transmission factor, radiation protection efficiency and lead's equivalent thickness due to the enrichment of Fe + Mn concentrations within the studied soils. The results show that the Black cotton soil exhibits better shielding properties for γ-ray than the other soils.

Effect of different metal oxides on the Radiation shielding features of borate glasses

Three zinc barium-borate glasses were produced in the current work, incorporating different metal oxides (MO) (CaO, TiO2, and CuO) via the melt quenching technique under a 1100 °C melting temperature for 60 min. The fabricated samples' density is 4.112 g/cm3, 4.157 g/cm3, and 4.261 g/cm3 for glasses dopped with CaO, TiO2, and CuO, respectively. Additionally, the Makishima-Mackenzie model was employed to evaluate the effect of metal oxides on the fabricated glasses' mechanical properties. The study shows that the glasses with TiO2 have the highest mechanical moduli and microhardness which reach 4.67 GPa. The gamma-ray shielding properties in the 0.033–2.506 MeV energy interval were estimated by applying Monte Carlo simulation. The study demonstrates that the glass samples containing CuO exhibit the highest linear attenuation coefficient (LAC) when compared to the glasses containing Ca and TiO2 compounds. The LAC of the CuO-doped glasses varied between 28.367 cm−1 and 0.163 cm−1 when the photon energy was raised between 0.033 MeV and 2.506 MeV. Also, the study shows good shielding parameters (half-value layer, lead's equivalent thickness, and radiation protection efficiency) for the glasses doped CuO compared to glasses doped Ca and TiO2.

Microstructure investigation, Electrical properties, and γ-rays’ protection capacity for ZnO doped clay ceramic

A series of ceramic samples fabricated based on ZnO doped different concentrations of natural clay according to the relation (1-x) ZnO – (x) clay; 5 wt% ≤ x ≤ 20 wt%. The samples were pressed and sintered at 1200 °C. The experimental techniques were used to characterize and measure the chemical composition, density, and current-voltage measurements for the fabricated ceramics samples. The measurements depict an increase in the I–V nonlinearity with raising the clay concentration, where the increase in clay by up to 20 wt% shifts breakdown voltage to a higher value of up to 390 V/cm and decreases leakage current to 55 mA/cm2. The examinations for the gamma-ray shielding capacity for the fabricated composites (utilizing Monte Carlo simulation) demonstrate enrichment of clay concentration between 5 wt% and 20 wt% reduced the linear attenuation coefficient for the fabricated ceramics by 23.15% and 8.66% at γ photon energy of 0.059 MeV and 1.252 MeV, respectively. The half-value thickness and lead's equivalent thickness increased along with a drop in the linear attenuation coefficient, but the radiation protection effectiveness of the fabricated ceramics increased.

X-ray attenuation performance of a newly synthesized tellurium based lead-free radiation shielding glass system

The lead-free quaternary glass systems containing B2O3–CaO–ZnO–TeO2 were synthesized using the traditional melt-quenching method. XRD analysis confirmed that the TeZnCaB glass system exhibited an amorphous behaviour. The density of the glass samples was increased from 3.48 g/cc to 4.08 g/cc by increasing the TeO2 concentration from 20 to 45 mol%. From UV–visible spectroscopy, it was observed that direct and indirect energy band gaps decreased with increasing the TeO2 concentration whereas the refractive index increased. TEM analysis revealed the amorphous behaviour along with nanocrystals present in the glass sample. X-ray attenuation measurements were performed to assess the radiation shielding properties of the lead-free glass system and observed that the radiation shielding capacity was increased with the TeO2 concentration. The best lead equivalent thickness was 2.02 mm for the sample with 45% TeO2 and these glasses could be promising materials for medical diagnostic applications.

Mathematical Calculation of X-Rays/Gamma-Rays Interaction with Zinc Bismuth Borate Glass Using Phy-x Program in Compton Energy Range

The zinc bismuth borate (ZBB)glasses have been calculated using Phy-X program at the Compton energy range. The ZBB glasses were decided in the concentration of Bi2O3 = 25, 30, 35 and 40 mol%. The mass attenuation coefficient, the effective atomic number, the effective electron density, the half value layer and the lead equivalent thickness were investigated. The results show the trend of values were decrease when the Compton energy increasing and found the values were higher when the concentration of Bi2O3 increases. The Zeff and Neff show similar trend showing that the values decrease with decrease in Bi2O3 content. The HVL value shows lowest with an increase in concentration of Bi2O3 suggesting their role to be good candidature for radiation shielding material applications. The lead equivalent thickness of glass samples shows a good trend when adding more concentration of Bi2O3 and found the highest value at 40 mol% of Bi2O3 concentration.

Scheelite-type BaWO4 doped with Ho2O3 oxide as a promising lead-free shield for gamma rays: Structural, optical properties, and radiation attenuation efficiency

Humans are constantly exposed to ionizing radiation and radioactive substances that exist naturally within the earth, their bodies, and their homes. Therefore, people and their surroundings must be protected from high levels of ionizing radiation. In general, different materials for radiation protection are used in diverse fields and for specific cases. In this work, a new ceramic-based material containing barium tungstate-doped with different amounts (x= 0–75%) of holmium oxide Ho2O3 was proposed as a γ-radiation shield. The structural and optical studies were performed based on X-ray diffraction technique, Fourier transform infrared spectrum, and diffuse reflectance spectroscopies. Radiation attenuation coefficients were determined using the Monte Carlo simulation. The structural analyses indicated that the BaWO4 crystal belongs to the scheelite structure and a lattice distortion was shown due to the effect of Ho2O3 doping. The band gap energy of the material increased progressively with increasing the content of the dopant in the host material. The radiation shielding coefficients reduced with increasing the concentration of Ho2O3 into BaWO4, where the linear attenuation coefficient reduced by 13% from 0.386 cm−1 to 0.338 cm−1 at 0.662 MeV when the concentration of Ho2O3 increased from 0% to 75%, respectively. Simultaneously, the lead equivalent thickness increased from 3.22 cm to 3.67 cm with raising the Ho2O3 concentration.

Effectiveness of shielding materials against 177Lu gamma rays and the corresponding distance relationship.

The purpose of this study is to determine the dose reduction of different shielding materials at various distances from a 177Lu photon radiation source. Two protective aprons with lead equivalent thicknesses of 0.25mm and 0.35mm and tungsten-containing rubber (TCR) were used as shielding materials. A vial containing 177Lu was sealed in a lead container so that a narrow beam went out through a 3mm-diameter hole. The dose rate was measured at distances of 0, 10, 50, 100, and 200cm from the source using a NaI scintillation survey meter to obtain the rate of dose reduction. TCR was tested with thicknesses ranging from 0.3 to 1.0mm at 0.1mm intervals and from 1.0 to 4.0mm at 0.5mm intervals. At distances of 0, 10, 50, 100, and 200cm, the dose reduction for the lead equivalent thickness of 0.25mm were 32.7%, 54.5%, 93.1%, 97.9%, and 99.6%, respectively; and for the lead equivalent thickness of 0.35mm were 53.4%, 70.6%, 95.6%, 98.9%, and 99.6%, respectively. Without any shielding, the dose rate decreased by 34.4% at 10cm and by 88.8% at 50cm from the radiation source. The dose reduction for the TCR thickness of 3.5mm was 89.8% at 0cm and 93.3% at 10cm. The TCR thickness of 0.4mm provided a dose reduction comparable to or greater than that of the 0.25mm lead equivalent, whereas the TCR thickness of 1.0mm or greater provided a dose reduction comparable to that of the 0.35mm lead equivalent. Achieving a reduction of 95% or more requires the 0.25mm lead equivalent for a distance of 100cm, the 0.35mm lead equivalent for 50cm, the TCR thickness of 0.3mm for 100cm, or the TCR thickness of 0.9mm for 50cm. Without wearing a protective apron, a reduction of approximately 95% is observed at distances greater than 100cm. These findings would be useful for medical staff engaging in related activities.

Synthesis of pristine CaZrO3 and CaZrO3/Pr6O11 ceramic samples and assessment of their radiation protection features

The past few decades have witnessed significant variations in the use of shielding materials and ionizing radiation. The use of ceramics as shields for protection against radiation has attracted interest in research owing to exceptional properties that distinguish them from other materials that are available to this end. Calcium zirconate (CaZrO3) is a lead-free ceramic material that exhibits good physicochemical properties, and is considered to be a good host for lanthanide elements, such as praseodymium ions, where this makes it a suitable alternative to lead and lead-based compounds as well as a promising candidate for use in radiation protection. In this study, we examine the radiation shielding properties of pristine CaZrO3 and Pr6O11/CaZrO3 ceramic samples by using Monte Carlo simulations. The formation of the desired phase was identified by the XRD technique. The data analysis indicated that the samples crystallized into an orthorhombic structure. The densities of the pristine CaZrO3 and the Pr6O11/CaZrO3 samples were 4.20 g/cm3 and 4.54 g/cm3, respectively. The analysis of their radiation shielding properties indicated an improvement in their linear attenuation coefficient (LAC), with values of 59.3%, 24.4%, 11.3%, and 8.1% at γ-photon energies of 0.121 MeV, 0.356 MeV, 0.662 MeV, and 2.506 MeV, respectively, when Pr6O11 was added to CaZrO3. The improvement in the LAC of the prepared samples was accompanied by a considerable reduction in their half-value thickness, lead-equivalent thickness, and transmission factor.

Influence of SrO on radiation shielding features of MgO-LiF-SiO2-Bi2O3 glasses: A simulation study

The γ-ray shielding parameters were evaluated using the Monte Carlo simulation for a quadrable glass system consisting of LiF-MgO-Bi2O3- SiO2 in the γ-ray energy interval extended between 0.284 MeV up to 1.332 MeV. The substitution of MgO by SrO compounds was studied in the present work where the raising SrO concentration was between 0 and 20 mol.% enhances slightly the linear attenuation coefficient of the fabricated glasses from 0.507 cm−1 to 0.514 cm−1, at a gamma ray energy of 0.662 MeV. The enhancement in the linear attenuation coefficient leads to a decrease in the half values thickness and the lead equivalent thickness for the investigated samples. The results from this work demonstrated that replacing magnesium with strontium led to improve radiation protection ability of the glasses.

A closer look at the structure and gamma-ray shielding properties of newly designed boro -tellurite glasses reinforced by bismuth (III) oxide

This work presents the synthesis and preparation of a new glass system described by the equation of (70-x) B2O3–5TeO2 –20SrCO3–5ZnO –xBi2O3, x = 0, 1, 5, 10, and 15 mol. %, using the melt quenching technique at a melting temperature of 1100 °C. The photon-shielding characteristics mainly the linear attenuation coefficient (LAC) of the prepared glass samples were evaluated using Monte Carlo (MC) simulation N-particle transport code (MCNP-5) at gamma-ray energy extended from 59 keV to 1408 keV emitted by the radioisotopes Am-241, Ba-133, Cs-137, Co-60, Na-22, and Eu-152. Furthermore, we observed that the Bi2O3 content of the glasses had a significantly stronger impact on the LAC at 59 and 356 keV. The study of the lead equivalent thickness shows that the performance of fabricated glass sample with 15 mol.% of Bi2O3 is four times less than the performance of pure lead at low gamma photon energy while it is enhanced and became two times lower the perforce of pure lead at high energy. Therefore, the fabricated glasses special sample with 15 mol.% of Bi2O3 has good shielding properties in low, intermediate, and high energy intervals.

An investigation into potential improvements in the design of lead glasses for protecting the eyes of interventional cardiologists

The lens of the eye can be damaged by ionising radiation, so individuals whose eyes are exposed to radiation during their work may need to protect their eyes from exposure. Lead glasses are widely available, but there are questions about their efficiency in providing eye protection. In this study, Monte Carlo simulations are used to assess the efficiency of lead glasses in protecting the sensitive volume of the eye lens. Two designs currently available for interventional cardiologists are a wraparound (WA) style and ones with flat frontal lenses with side shielding. These designs were considered together with four modifications that would impact upon their efficiency: changing the lead equivalent thickness, adding lead to the frames, elongating the frontal lenses, and adding a closing shield to the bottom rim. For the eye closest to the source, standard models of lead glasses only decrease the radiation reaching the most sensitive region of the eye lens by 22% or less. Varying the lead thickness between 0.4 mm and 0.75 mm had little influence on the protection provided in the simulation of clinical use, neither did adding lead to the frames. Improved shielding was obtained by elongating the frontal lens, which could reduce radiation reaching the eye lens by up to 76%. Glasses with lenses that had a rim at the base, extending towards the face of the user, also provided better shielding than current models, decreasing the dose by up to 80%. In conclusion, elongating the frontal lens of lead glasses, especially of the WA design, could provide a three-fold increase in shielding efficiency and this is still valid for lenses with 0.4 mm lead equivalence.

New Radioprotective Device that can be Used for Fluoroscopic Exam: Possibility to Contribute to Staff Exposure Protection During VFSS.

The videofluoroscopic swallowing study (VFSS) is a recognized standard diagnostic imaging technique that is used to investigate swallowing disorders and dysphagia. Patients were assessed in a seated posture on a chair or wheelchair. Using X-ray fluoroscopy, the state of patients' swallowing was checked by eating and drinking according to the physician's instructions. VFSS procedures are prolonged, and VFSS staff members are exposed to radiation. Therefore, we evaluated original lead shielding device (OLSD) that can be attached to the handrail of a table and placed vertically. The OLSD has a lead-equivalent thickness of 0.3 mmPb, weighs about 6kg, and has the dimensions 50cm × 50cm × 8.0mm. We used a human phantom and a radiation survey meter with and without protection from scattered radiation at the positions of the physician and medical staff at the height of 150cm above the floor (i.e., the height of the eye's crystalline lens). After measuring the scattered radiation, we created radiation maps with and without the OLSD. The dose rate at the physician's position without and with the OLSD was 190 µSv/h and 92 µSv/h, respectively, and a dose reduction of 51.6% with the plate. Moreover, the radiation maps added clarity to the distribution of the scattered radiation. Such information should lead to greater awareness about exposures to physicians and other medical staff. Thus, the OLSD effectively provided protection from scattered radiation at the physician's position during fluoroscopy. It may contribute to the reduction of staff exposure for VFSS.

Radiation shielding properties of Silicon boron alloys

The current study focuses on the shielding properties of selected Silicon-Boron alloys like of various compositions. Lower value of mass attenuation coefficient (MAC), half value thickness (HVL), tenth value thickness (TVL), penetration depth, electron density (Ne), effective atomic number (Zeff) and higher lead equivalent thickness, Radiation Protection Efficiency (RPE) and KERMA value which are essential characteristics of a good absorber for Si0.95B0.05. From these observations, it is clear that the silicon boron alloy Si0.95B0.05 is found to have larger value of mass attenuation coefficient, effective atomic number, radiation protection efficiency and KERMA, however, HVL, TVL and penetration found to be small. Furthermore, the EMI shielding parameter (total shielding effectiveness) was also found to be larger for the silicon boron alloy Si0.95B0.05 in near infrared, mid infrared, far infrared, ultra-high frequency (UHF), very high frequency, high frequency radio waves, middle frequency radio waves, low frequency radio waves and very low frequency radio waves. Neutron scattering lengths and cross-sections for the above alloys are also studied. This is identified as a good characteristic of X-ray/gamma absorber radiation, neutron shielding and EMI radiations. Thus, the Si-B alloy, Si0.95B0.05 may be used for X-ray/gamma radiation shielding.

Evaluations for Determination of Optimum Shields in Nuclear Medicine

Background: 131I source is widely used in the treatment of hyperthyroidism and thyroid cancers. 131I emits both beta and gamma-rays. Radiation protection is considered for gamma rays emitted by 131I. It seems no special shield against 131I source to be designed.Objective: This research aims to evaluate determination of optimum shields in nuclear medicine against 99Tcm and 131I sources by dosimetric method. Additionally, Monte Carlo simulation was used to find the optimum thickness of lead for protection against 131I source.Material and Methods: This is an experimental research in the field of radiation protection. A calibrated model of GraetzX5C Plus dosimeter was used to measure exposure rates passing through the shields. The efficiency of the shields was evaluated against 99Tcm and 131I. Furthermore, Monte Carlo simulation was used to find the optimum thickness of lead for protection against 131I source.Results: The findings of the dosimetric method show that the minimum and maximum efficiencies obtained by the lead apron with lead equivalent thickness of 0.25 mm and the syringe holder shields with thickness of 0.5 mm lead were 50.86% and 99.50%, respectively. The results of the simulations show that the minimum and maximum efficiencies obtained by lead thicknesses of 1 mm and 43 mm were 19.36% and 99.79%, respectively. Conclusion: The optimum shields against 99Tcm are the syringe holder shield, the tungsten syringe shield, and the lead partition, respectively. Furthermore, based on simulations, the thicknesses of 11-28 mm of lead with efficiencies between 90.6% to 99% are suggested as the optimum thicknesses to protect against 131I source.

GAMMA RAY SHIELDING PARAMETER OF BARIUM-BORO-TELLURITE GLASS

Boro-tellurite glasses have recently been attracting the attention of several researchers as a tremendous optical device and shielding material. In this work, we have synthesized borotellurite glasses with barium oxide (BaO) by melt quenching technique. The structural and shielding property changes after adding of barium oxide in boro-tellurite glass were studied using Fourier Transform Infrared (FTIR) and Lead Equivalent Thickness measurement (LET), respectively. The results show that the bismuth oxide increases glass density, changes the glass structure, and increases the radiation shielding properties. Changes in the glass structure are due to atomic rearrangements and formation of nonbridging oxygen (NBO). The density of boro-tellurite glass system increased when BaO content increased, which is due to the high molecular weight of BaO and the increasing number of non-bridging oxygen (NBO) atoms in the glass structure. In addition, the mass attenuation coefficient, μm of the glass system increases as BaO concentration increases and the half value layer, HVL and mean free path, MFP of 30BaBTe glass is better than some standard concretes.

Radiation shielding properties of BaO:WO3:Na2O:B2O3 glass system using WinXCom program in the range of 1 keV to 100 GeV: Theoretical calculation

The research aimed to study the radiation shielding properties of xBaO-5WO3-15Na2O-(80-x)B2O3 glass system where x = 5, 10, 15, 20, 25, 30 and 35 mol%. The theoretical values calculated using WinXCom program in the range of 1 keV to 100 GeV energy regions. The results of calculation found that the mass attenuation coefficients were increased with increase in BaO concentration and decreased with the increasing energy. Moreover, these glass system at low energies show discontinuities corresponding to photoelectric absorption edges of tungsten and barium. For the partials interaction at the low energies range the photoelectric absorption is the main interaction in these energy regions. At the medium energy regions, the radiation shielding parameters are almost constants dominated by Compton scattering process. In the high energy regions, pair production becomes the main interaction process over the energy. It can also be concluded that the characteristics of radiation shielding parameters for the glasses system depend on different barium in this concentration and the energy regions. The lead equivalent thickness of glass samples show that glass samples increasing trend with increase in concentration of BaO and the experimental are good agreement with theoretical value.
