Effect of ZrO₂ Reinforcement on Photon Transmittance in Functionally Graded Composite Materials

Abstract

Lead is frequently used as a radiation shielding material; however, it is a toxic material and prolonged exposure can cause serious health problems, including neurological and psychiatric disorders. Alternative radiation shielding materials to lead are currently being widely researched. In this study, the linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), half value layer (HVL), tenth value layer (TVL), and mean free path (MFP) parameters of the Al 2024 matrix ZrO2 ceramic-reinforced functionally graded composite material (FGCM) were investigated using the Phy-x/PSD program. It was observed that photons were better absorbed in higher-density ZrO2 layers.

Fonksiyonel Derecelendirilmiş Kompozit Malzemelerde ZrO₂ Takviyesinin Foton Geçirgenliği Üzerindeki Etkisi

Öz

Kurşun, radyasyona karşı zırh malzemesi olarak sıklıkla kullanılmaktadır; ancak toksik bir malzemedir ve uzun süreli maruziyet durumunda nörolojik ve psikiyatrik bozukluklar da dâhil olmak üzere ciddi sağlık sorunlarına neden olabilir. Kurşuna alternatif radyasyon zırh malzemeleri günümüzde yaygın olarak çalışılmaktadır. Bu çalışmada, Al 2024 matrisli ZrO2 seramik takviyeli fonksiyonel derecelendirilmiş kompozit malzemenin (FDKM) doğrusal zayıflama katsayısı (LAC), kütle zayıflama katsayısı (MAC), yarı değer kalınlığı (HVL), onda bir değer kalınlığı (TVL) ve ortalama serbest yol (MFP) parametreleri Phy-x/PSD programı kullanılarak incelenmiştir. Fotonların daha yüksek yoğunluklu ZrO2 katmanlarında daha iyi emildiği gözlemlenmiştir.
