A Closer Look on Nuclear Radiation Shielding Properties of Eu3+ Doped Heavy Metal Oxide Glasses: Impact of Al2O3/PbO Substitution

Abstract

In this study, a group of heavy metal oxide glasses with a nominal composition of 55B2O3 + 19.5TeO2 + 10K2O + (15−x) PbO + xAl2O3 + 0.5Eu2O3 (where x = 0, 2.5, 5, 7.5, 10, 12.5, and 15 in wt.%) were investigated in terms of their nuclear radiation shielding properties. These glasses containing lanthanide-doped heavy metal oxide were envisioned to yield valuable results in respect to radiation shielding, and thus a detailed investigation was carried out; the obtained results were compared with traditional and new generation shields. Advanced simulation and theoretical methods have been utilized in a wide range of energy regions. Our results showed that the AL0.0 sample with the highest PbO contribution had superior shielding properties in the entire energy range. The effective removal of cross-sections for fast neutrons (ΣR) was also examined. The results indicated that AL5.0 had the greatest value. While increasing the concentration of Al2O3 in samples had a negative effect on the radiation shielding characteristics, it can be concluded that using PbO in the Eu3+ doped heavy metal oxide glasses could be a useful tool to keep gamma-ray shielding properties at a maximum level.

Study on Radiation Shielding Properties of New Barium-Doped Zinc Tellurite Glass

“…In addition, the density and radiation-shielding ability of glass can be significantly improved by doping various heavy metal elements (such as Bi, Pb, Ba, and Gd). Many research groups have reported on glass of various substrates and their nuclear protective properties in the literature [ 9 , 10 , 11 ].…”

The influence of Nd2O3 on the radiation shielding, physical, mechanical, and acoustic properties of the (75 − x)TeO2–15MgO–10Na2O–xNd2O3 glasses as a potent radiation shielding material

“…The cost, noncorrosive, eco-friendly properties, high transparency, non-toxic nature, and good mechanical features are the advantages of using glasses as shielding materials. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] Researches show that tellurite glass is extremely effective against gamma photon in comparison with the other types of glasses. [20][21][22][23] Sayyed [22] surveyed the effect of the Bi 2 O 3 on the shielding ability of the tellurite glass with the general formula of TeO 2 -B 2 O 3 -ZnO.…”
