“…The derived Σ R results specify that for any glass, the proper mixture of both light (e.g., B) and heavy (e.g., Bi) elements is essential in attaining better attenuation effectiveness for fast neutrons. Additionally, glass S6 Σ R value is compared with distinct established (e.g., graphite, H 2 O, concretes) and some other freshly reported radiation shielding substances Σ R quantities [8,22,23,31,[33][34][35][36]39,45,53,55,59] and listed in Table 3. SSS30 glass 0.08931 [35] TZNG-E glass 0.1125 [36] S5 glass 0.1375 [39] E glass 0.1474 [45] S7 glass 0.1232 [53] Following Table 3 data, one can identify that, proportionately, S6 glass possesses a greater Σ R than respective graphite, H 2 O, OC, HSC, and ILC [59], G8 [8], and G0 [22] glasses, S0 glass-ceramic [23], PA-6 and PVDC polymers [33], SSS30 [35], and TZNG-E [36] glasses values, and a lower Σ R than BBLNi6 [55] glass, NS1 alloy and SMC [31], and VTBi6 [34], S5 [39], E [45], and S7 [53] glasses quantities.…”
