“…The synthesis and development of shielding materials is a fertile research area, and multiple investigations have been conducted to provide effective radiation protection tools. [9][10][11] Despite the considerable number of guidelines published by specialized radiation protection organizations and professional societies, some controversies remain regarding the utility and efficiency of shielding practice. Marsh and Solisky (2019) challenged radiographers to rethink patient shielding practice.…”

“…However, different types of shields and dose reduction methods are being investigated. [9][10][11][12][13] This has encouraged us to perform this experimental investigation on the effectiveness of breasts and eyes shielding during Cervical Spine (CS) radiography. CS radiography is a frequent radiological examination undertaken to rule out cervical injures.…”

This study assessed the effectiveness of breast and eye shielding and measured the radiation dose to radiosensitive tissues (eyes and breasts) due to scatter radiation during cervical spine X-ray radiography examinations. Methods: Using an anthropomorphic phantom, the scattered radiation dose was measured before and after the placement of the lead shield over the eyes and breasts in the anteroposterior (AP) and left lateral projection. A regression formula was utilized to determine the exposure. Mean values and standard deviation of breasts and eyes doses were calculated. The paired two sample t-test was used to compare the recorded dose before and after shielding placement. Results: Radiation shielding of eyes and breasts during AP cervical spine X-ray decreased radiation dose to the breasts by 99.9% and to the left and right eye by 91% and 89%, respectively. For the left lateral cervical spine X-ray, the radiation dose decreased by 26% and 31% for the left and right eye, respectively, and by 23% and 99% for the left and right breast, respectively. A significant difference was noted comparing the dose before and after the implementing shielding on the eye and breast. Conclusion:According to the results presented, the dose is significantly reduced, especially considering that they are not in the area of interest but are exposed to scatter radiation.

“…The shielding characteristics such as MAC (μ/ρ), EAN (Zeff), HVL, MFP, RPE, and EBF are evaluated theoretically to explore the proficiency of the Cr2O3 -Ba(La)2SiO6 glasses. The subsequent equation can be employed to calculate the experimental LAC (μ -linear attenuation coefficient) values [25,26]. The variation in the MAC (cm 2 /g) against photon energy (~ 0.015 to 15 MeV) with an increase in the Cr2O3 concentration is presented in Fig.…”

The research on Cr2O3 doped SiO2 glasses is well known for advanced dielectrics. However, there are many other valuable properties associated with Cr2O3 inclusive various glasses. In this view, the current research aimed to develop the radiation shielding, elastically rich, and the EPR based Cr2O3 doped Ba(La)2SiO6 glass resource. Electron paramagnetic resonance, radiation shielding, and elastic studies have been employed to investigate the advanced characteristics. Structural characterization suggests glassy behavior with the Cr2O3 undoped glass. Whereas the other involved with Cr2O3 mol% shown with the ceramic behavior. The glass transition phenomena and forming abilities are studied with the help of differential thermal analysis techniques. Elastic studies have been done with the limit on the glasses, which suggests the glasses are flexible for elastic use. The electron paramagnetic resonance reports suggest high order of dipole-dipole super-exchange interaction and rhombohedral distortion within the glasses. Furthermore, we have tested the glasses for radiation shielding properties. The values of mass attenuation coefficient, radiation protection efficiency, mean free path, and energy absorption build-up factor of the glasses are measured and compared with values obtained with the help of standard photon shielding and dosimetry software. The studies indicate that the glasses developed are capable of radiation shielding. Upon 50 kGy, γ - irradiation, the thermoluminescence properties of the glasses are reported. The results found to be interesting, and reveal the resource developed are thermoluminescent at low activation energies. Furthermore, we have tested, the glasses for radiation shielding properties. Moreover, to introduce the detailed correlation between electron paramagnetic resonance, and thermoluminescence phenomenon, we have annealed the glasses under 0 to 300 oC temperature and upon the 0 to 50 kGy, γ - irradiation dose level. The electron paramagnetic resonance and thermoluminescence properties obtained for the glasses are highly correlative.

“…The mass attenuation coefficient ( ) is one of these parameters; it indicates the amount of photons scattered or absorbed by the interacting material. The mass attenuation coefficient is regarded as a fundamental parameter that can be used to calculate additional shielding parameters [19][20][21][22][23]. Additionally, the effective atomic number (Zeff) is a critical parameter for interpreting the attenuation efficiency of gamma photons by a multi-element substance.…”

“…Zeff indicates the protective material's efficiency; a higher Zeff value indicates that photons are more likely to be absorbed due to the presence of more electrons to communicate with. Additionally, since the mean free path (MFP) is an energy-dependent quantity, it allows the determination of the distance traveled by a photon in a sample prior to any interaction [23][24][25][26]. The mass attenuation coefficients (MAC) for 0.015-15 MeV gamma-ray energies are determined using the Py-MLBUF online software in order to determine the photon shielding parameters of the BSABa-x glass systems tested in this analysis.…”

The aim of this research is to examine the radiation shielding properties of 5B2O3-40SiO2-(55-x)Al2O3-xBaO (BSABa-x) (where x = 25, 28, 31 and, 34) lead-free glass systems, which are containing barium and aluminum oxide added to borosilicate glasses, with varying from 25 to 34 weight fractions. Shielding parameters, such as linear attenuation coefficients (LAC), mass attenuation coefficients (MAC), mean free path (MFP), effective atomic number (Zeff), effective electron density (Neff), half-value layer (HVL), tenth-value layer (TVL), effective atomic weight (Aeff), exposure buildup factors (EBF) and energy absorption buildup factors (EABF) enable us to obtain information about the radiation shielding power of composite glass material groups. Therefore, the mass attenuation coefficients (MAC), for the 0.015-15 MeV gamma-ray energies are obtained by using the Py-MLBUF online software to determine photon shielding parameters of BSABa-x glass systems. The results are shown that the glass system, which contains higher BaO concentration has higher mass attenuation coefficients. BSABa-34 glass has the highest MACs, ranging from 0.111 cm 2 /g to 90.400 cm 2 /g, while BSABa-25 glass has the lowest values, ranging from 0.099 cm 2 /g to 69.000 cm 2 /g. The BSABa-34 glass with the highest BaO contribution has the thinnest MFP and HVL values. In addition, photon buildup is minimized by adding BaO to the BSABa-x glasses. Accordingly, we can conclude that adding BaO to aluminum borosilicate glasses at increasing rates, improves nuclear radiation resistance properties.
