B2O3-Bi2O3-TeO2-BaO and TeO2-Bi2O3-BaO glass systems: a comparative assessment of gamma-ray and fast and thermal neutron attenuation aspects

Lakshminarayana, G.; Dong, M. G.; Al-Buriahi, M. S.; Kumar, Ashok; Lee, Dong-Eun; Yoon, Jonghun; Park, Taejoon (SPRINGER HEIDELBERG, 2020)

For Pb-free 35B(2)O(3)35Bi(2)O(3)(30-x)TeO2(x)BaO (x=5, 10, 15, 20, and 25 mol%) and (90-x)TeO(2)10Bi(2)O(3)(x)BaO (x=10, 15, and 20 mol%) glass systems, gamma and neutron (both fast and thermal neutron) radiation shielding ...
Binary B2O3-Bi2O3 glasses: scrutinization of directly and indirectly ionizing radiations shielding abilities

Lakshminarayana, G.; Kumar, Ashok; Tekin, H. O.; Issa, Shams A. M.; Al-Buriahi, M. S.; Lee, Dong-Eun; Yoon, Jonghun; Park, Taejoon (ELSEVIER, 2020)

For five B2O3-Bi2O3 glasses, detailedly, gamma, neutron, & proton, alpha, and electron (charged particles) shielding efficacies were assessed in this work. The crucial photon attenuating (interaction probabilities) parameter ...
Comparative assessment of fast and thermal neutrons and gamma radiation protection qualities combined with mechanical factors of different borate-based glass systems

Lakshminarayana, G.; Tekin, H. O.; Dong, M. G.; Al-Buriahi, M. S.; Lee, Dong-Eun; Yoon, Jonghun; Park, Taejoon (ELSEVIER, 2022)

Adequate shielding from ionizing radiations is essential in nuclear facilities because of such radiations' adverse effects on humans in the event of unwanted or accidental exposure. In the current work, for four distinct ...
Estimation of gamma-rays, and fast and the thermal neutrons attenuation characteristics for bismuth tellurite and bismuth boro-tellurite glass systems

Lakshminarayana, G.; Kebaili, Imen; Dong, M. G.; Al-Buriahi, M. S.; Dahshan, A.; Kityk, I., V; Lee, Dong-Eun; Yoon, Jonghun; Park, Taejoon (SPRINGER, 2020)

Gamma-rays and fast and thermal neutron attenuation features of (Bi2O3)(x)-(TeO2)((100-x)) (where x = 5, 8, 10, 12, and 15 mol%) and [(TeO2)(0.7)-(B2O3)(0.3)]((1-x))-(Bi2O3)(x) (where x = 0.05, 0.10, 0,15, 0.20, 0.25, and ...
