Kolemanit Minerali ile Katkılanmış Lityum Borat Camların Gama-ışını Zırh Özellikleri

Bu çalışmada, (Li2B4O7) (100-x) - (Kolemanit) x cam sistemler (burada x = 10, 20, 30 ve % 40 ağırlık) erime söndürme tekniği ile üretildi. Üretilen camların, kütle soğurma katsayısı (µ? ), etkin atom numarası (Zeff), elektron yoğunluğu (Nel), yarı değer kalınlıkları (HVL) ve ortalama serbest yol (MFP) gibi radyasyon zırh parametreleri 81, 276, 302, 356 ve 383 keV gama enerjilerinde deneysel olarak Hp-Ge dedektörü ile ölçüldü. Ayrıca, camların bu radyasyon zırh parametrelerinin 1 keV-105 MeV enerji aralığında teorik hesaplamaları için WinXCom programı kullanıldı. Deneysel ve teorik sonuçların birbirleri ile iyi uyum içinde olduğu görüldü. Elde edilen sonuçlar, cam sistemindeki kolemanit mineralinin yüzdesi arttığında, µ? , Zeff ve Nel değerlerinin de arttığını ortaya koydu. Ayrıca, bunun aksine, kolemanit yüzdesinin artmasıyla HVL and MFP değerlerinin azaldığı gözlendi. Spesifik olarak, incelenen camlar arasında yüzde 40 kolemanit mineral içeriğine sahip lityum borat cam en yüksek µ? , Zeff ve Nel değerine sahip, bununla birlikte en düşük HVL ve MFP'ye sahiptir. Bu nedenle, bu çalışmada, incelenen cam sistemleri arasında %40 kolemanit minerali içeren lityum borat cam gama radyasyonu zırh özellikleri için en iyi sonucu vermiştir.

Gamma-ray Shielding Properties of Lithium Borate Glass Doped with Colemanit Mineral

In this study, (Li2B4O7)(100-x)-(Colemanite)x glass systems (where x=10, 20, 30 and 40 wt %) were fabricated viamelt quenching technique. The radiation shielding parameters of produced glasses such as mass attenuationcoefficient (µ?), effective atomic number (Zeff), electron density (Nel), half value layer (HVL) and mean free path(MFP) were measured experimentally for 81, 276, 302, 356, and 383 keV gamma ray energies with Hp-Gedetector. Also, WinXCom software was employed for theoretical calculation above radiation shielding parametersof glasses for 1 keV to 105 MeV energy region. It was seen that the experimental and theoretical results are goodagreement with each other. The obtained results revealed that when percentage of colemanite mineral has beenincreased in the glass system, µ?, Zeff and Nel values increase. Furthermore, it was observed that the values ofHVL and MFP, in contrary, decreases with increasing colemanite mineral percent. In specific, among theinvestigated glasses, lithium borate glass with 40 percentage colemanite mineral has the highest value of µ?, Zeffand Nel, however, it has the lowest HVL and MFP. Therefore, lithium borate glass with 40 percentage colemanitemineral has given the best results for gamma radiation shielding purpose among the investigated glass systems inthis work.
