Abstract

The development of lightweight and high-performance materials capable of providing effective shielding against ionizing radiation is of paramount importance for nuclear technology, medical diagnostic and therapeutic systems, and industrial radiation applications. In this study, commercially available Al 2024 alloy was reinforced with Al₂O₃ ceramic particles at different weight percentages (5wt%, 10wt%, and 15wt%). The Photon Shielding and Dosimetry (PSD) software was utilized to evaluate the theoretical X and gamma-ray’s attenuation capabilities of the fabricated composites across an energy spectrum spanning from 1 keV to 15 MeV. To evaluate the shielding efficiency, core radiation parameters including the mass (MAC) and linear (LAC) attenuation coefficients, alongside the mean free path (MFP), were analyzed together with the half- and tenth-value layers (HVL and TVL). The calculation results indicated that the S4 material exhibited the best gamma shielding performance, with its LAC values changing from 7102.069 cm-1 to 0.064 cm-1 within the energy range of 1 keV to 15 MeV. On the other hand, within the 0.00804 MeV to 0.05038 MeV energy range, the S1 material demonstrated the poorest performance against characteristic X-rays, with its MFP values ranging between 0.008 cm and 0.712 cm.

Özet

İyonlaştırıcı radyasyona karşı etkili koruma sağlayabilen hafif ve yüksek performanslı malzemelerin geliştirilmesi, nükleer teknoloji, tıbbi tanı ve tedavi sistemleri ve endüstriyel radyasyon uygulamaları için büyük önem taşımaktadır. Bu çalışmada, ticari olarak temin edilebilen Al 2024 alaşımı, farklı ağırlık yüzdelerinde (%5, %10 ve %15) Al₂O₃ seramik parçacıklarıyla güçlendirilmiştir. Kompozitlerin teorik olarak X ve gama ışınlarının zayıflama kapasitelerini 1 keV ile 15 MeV arasında değişen bir enerji spektrumunda değerlendirmek için Foton Zırhlama ve Dozimetri (PSD) yazılımı kullanılmıştır. Zırhlama verimliliğini değerlendirmek için, kütle (MAC) ve doğrusal (LAC) zayıflama katsayıları ile birlikte ortalama serbest yol (MFP) dâhil olmak üzere temel radyasyon parametreleri, yarı ve onda bir değer kalınlığı (HVL ve TVL) ile birlikte analiz edilmiştir. Hesaplama sonuçlarına göre, S4 malzemesinin en iyi gama zırhlama performansını sergilediğini ve LAC değerlerinin 1 keV ile 15 MeV enerji aralığında 7102.069 cm-1 ile 0.064 cm-1 arasında değiştiğini göstermiştir. Öte yandan, 0.00804 MeV ile 0.05038 MeV enerji aralığında, S1 malzemesi karakteristik X ışınlarına karşı en zayıf performansı göstermiş olup, MFP değerleri 0.008 cm ile 0.712 cm arasında değişmektedir.
