P2O5 Katkılı Lityum Alüminyum Silikat (LAS) Cam Sistemlerinin Nükleer Radyasyon Zırhlamasına Etkisi

Öz

Bu çalışmada, XCOM veritabanının Windows sürümü olan WinXCom programı kullanılarak LAS (lityum-alüminyum-silikat) Li₂O-Al₂O₃-SiO₂ cam örneklerinin zırhlama parametreleri hesaplanmıştır. Kullanılan cam örneklerinde P₂O₅ konsantrasyonunun artan yüzde oranının zırhlama parametreleri üzerindeki değişim etkisi incelenmiştir. Gama ışını için malzemelerin koruyusu etkisi, malzemelerin zırhlama etkilerini anlamada kilit rol oynayan birkaç farklı zırhlama parametresi yardımıyla yorumlanabilir. µ_m=μ/ρ ile tanımlanan kütle zayıflama katsayısı, zırhlama parametrelerini hesaplamak için kullanılan en temel katsayıdır. Bu parametreler ortalama serbest yol (MFP), yarı değer katmanı (HVL), onuncu değer katmanı (TVL), etkili elektron numarası (N_e) ve eşdeğer atom numarasıdır (Z_eq). Ayrıca maruz kalma faktörü (EBF) ve GP fitleme parametreleri de Li₂O-Al₂O₃-SiO₂ cam örnekleri için logaritmik enterpolasyon yöntemi ve Z_eq değerinin kullanılması ile hesaplanmıştır. Li₂O-Al₂O₃-SiO₂ cam örnekleri için EBF değerleri, N_e ile ters bir ilişki göstermektedir. Ayrıca, P1 cam örneği için EBF değeri maksimum değeri alırken (en az N_e), P6 cam örneği için minimum EBF değeri (en yüksek N_e) hesaplanır. Seçilen camlar için farklı zırhlama parametrelerinde gözlenen değişiklik, madde ile üç etkileşim göz önünde bulundurularak yorumlanmaktadır bu etkileşimler fotoelektrik etki, Compton saçılması ve çift oluşumdur. Elde edilen sonuçlar, kütle zayıflatma katsayısı (µ_m) değerinin fotonun enerjisine, cam örneklerinin kimyasal bileşimine ve zırhlama malzemelerinin yoğunluğuna bağlı olduğunu göstermektedir. En yüksek P₂O₅ konsantrasyonuna sahip olan P6 cam numunesinin diğer Li₂O-Al₂O₃-SiO₂ cam örnekleri arasından nükleer radyasyon koruma kabiliyeti bakımından en etkili cam numunesi olduğunu açıkça görülmektedir.

Effect of P2O5 Additive on Nuclear Radiation Shielding Behaviors of Lithium Aluminum Silicate (LAS) Glass System

Abstract

In this work, shielding parameters of LAS (lithium-aluminum-silicate) Li₂O-Al₂O₃-SiO₂ glass samples have been reported with the help of the WinXCom code, a Windows version of the XCOM database. The effect of increasing P₂O₅ concentration on the shielding parameters has been examined in the used Li₂O-Al₂O₃-SiO₂ glass samples. The shielding effectuality of the materials for gamma-ray can be interpreted with the help of several different attenuation parameters which plays key role in understanding the shielding capabilities of the material. The mass attenuation coefficient, defined by µ_m=μ/ρ, is the most basic coefficient used to calculate the shielding parameters. These parameters are the mean free path (MFP), half value layer (HVL), tenth value layer (TVL), effective electron number (N_e) and equivalent atomic number (Z_eq). The exposure buildup factor (EBF) and GP fitting parameters are also calculated by the method of logarithmic interpolation using Z_eq of a Li₂O-Al₂O₃-SiO₂ glass system. The EBF values for Li₂O-Al₂O₃-SiO₂ glass samples show an inverse relation with N_e. Further, P1 (least N_e) offers maximum values of EBF and P6 (highest N_e) offers minimum EBF values. The change in different shielding parameters for the selected glasses was interpreted by considering three interactions with the substance (Photoelectric effect, Compton scattering and pair production). The obtained results show that the µ_m strongly depends on the photon energy, chemical composition and density of the shielding materials. It is clear to see that P6 glass sample having the highest P₂O₅ concentration is the most effective glass sample among the other glasses of Li₂O-Al₂O₃-SiO₂ system in nuclear radiation shielding ability.
