Investigation of the Efficiency of Shielding Gamma and Electron Radiation Using Glasses Based on TeO2-WO3-Bi2O3-MoO3-SiO to Protect Electronic Circuits from the Negative Effects of Ionizing Radiation

“…In view of this, the absorption efficiency depended not only on the Z eff value, but as the results of a number of experimental studies show, an increase in absorption efficiency was due to the synergistic effect of absorption due to a large number of different ions in the glass structure and the presence of a large number of absorbing centers capable of reducing the intensity of passing gamma rays as well as that of the resulting secondary radiation. Similar effects were observed in a number of works [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ] focusing on the effects associated with changes in the elemental composition of glasses due to the variation of the components, which, in turn, affects the absorption capacity. These effects are associated with a change in the electron density distribution, as well as differences in the atomic radii and their masses of the elements of the glass components, which, when interacting with gamma radiation, play a very important role in absorption.…”

“…The potential of telluride glasses for shielding gamma and neutron radiation in a wide energy range has been reported in a number of works, and in most of them the concept of creating protective shielding materials is based on an increase in the Z eff value, a characteristic that is responsible for the absorbing ability of the material, due to the fact that the absorption of gamma radiation is directly dependent on the given value of the material in which braking occurs [ 28 , 29 ]. However, for microelectronics, especially those used in spacecraft, the use of classical lead-based shielding materials is not advisable due to their large mass, which leads to an increase in the overall dimensions and weight of microelectronic devices [ 30 , 31 , 32 , 33 , 34 , 35 ]. In view of this, the main aim of this work is to assess the prospects of using telluride glasses doped with MoO 3 and SiO to create local protection against the ionizing radiation of microelectronic devices by depositing thin glasses with high absorption capacity and screening characteristics on the most important nodes.…”

Monte Carlo simulations study on gamma ray–neutron shielding characteristics for vinyl ester composites

“…From the obtained results, it can be concluded that the composite coded as V-P50 contains the largest total macroscopic attenuation, while the lowest number of hydrogen and oxygen atoms are obtained. [25] This discrepancy is due to the relevancy and strong linearity of the P t to the density of the samples that is clear in Figure 19. On the other hand, in the present vinyl ester composites, the weight percentages of low Z materials like hydrogen and oxygen vary in lower range, while this variation for density is in higher ranges.…”

Assessment of Gamma Ray Shielding Properties for Skin

“…The conventional shielding materials for several years are lead, tungsten, and other heavy elements. Besides these materials which have a high absorption rate, researcher developed new alternative materials due to negative aspect of this conventional materials [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In order to obtain cell from harmful radiation effect, the shielding character of the skin itself should be known.…”
