Broad and Narrow Photon Transmission and Energy Absorption Parameters of SiO2-Al2O3-Na2O-NaF-YF3 Silicate Glasses
摘要
This study highlights the influence of replacing Na2O with NaF on the photon interaction parameters of 40SiO2-20Al2O3-(10 + x)Na2O-(20-x)NaF-10YF3 (for x = 0, 2, 5, 7, 10). The mass attenuation coefficients (MACs) and mass energy absorption coefficients (MEACs) of the glass ceramics were computed for gamma-rays in the 15 keV-15MeV energy range using the NIST-XCOM database. The MAC and MAEC vary within the ranges of 0.0224–10.1508 cm2/g and 0.0156–6.4896 cm2/g for Si-ANNYF1, 0.0223–9.8821 cm2/g and 0.0164–6.3694 cm2/g for Si-ANNYF2, 0.0222–9.6097 cm2/g and 0.0163–6.2508 cm2/g for Si-ANNYF3, 0.0221–9.3724 cm2/g and 0.0163–5.5476 cm2/g for Si-ANNYF4, and 0.0220–9.1310 cm2/g and 0.0162–5.4131 cm2/g for Si-ANNYF5. The analysis of other estimated parameters showed that increasing the relative weight proportion of NaF2 relative to Na2O influenced the ability of the glass ceramics to interact and absorb energy from incident gamma photons. Adding more NaF made the glass ceramics better at confining photons in both the narrow and broad beams scenarios. The Si-ANNYFx glass ceramics are recommended for gamma shielding applications in nuclear industries.
