Katmanlı Üretim Uygulamaları için Samaryum Oksit Katkılı Fotopolimer Kompozitlerin Radyasyon Zırhlama Özelliklerinin İncelenmesi

Öz

Bilimsel ve endüstriyel gelişmelerle birlikte iyonize radyasyonun kullanımı arttıkça, radyasyona maruz kalmayı azaltmak için en son teknolojiye sahip ve çevresel olarak koruyucu malzemelere olan ihtiyaç da artmıştır. Bu çalışmada, katmanlı imalat uygulamaları için oluşturulan samaryum oksit (Sm2O3) katkılı fotopolimer kompozitlerin gama radyasyonu zayıflatma özellikleri incelenmiştir. Bu çalışmada, ağırlıkça %0, %10, %20 ve %50 Sm2O3 içeren kompozitler teorik olarak tasarlanmıştır. Malzemelerin radyasyon etkileşim parametrelerini 81 keV ile 1408 keV arasında değişen gama enerjilerinde incelemek için GAMOS Monte Carlo simülasyon kodu kullanılmıştır. Sonuçlar, katkı maddesi konsantrasyonu arttıkça doğrusal zayıflama katsayısının (LAC) ve kütle zayıflama katsayısının (MAC) önemli ölçüde arttığını, yarı değer tabakası (HVL) kalınlığının ise azaldığını göstermiştir. Özellikle 81 keV'lik düşük enerji seviyesinde, %50 Sm2O3 içeren Sm50 numunesi, katkısız numuneye kıyasla en yüksek radyasyon zayıflatma performansını sergilemiştir. Sonuç olarak, 3D baskı teknolojisi kullanılarak üretilen samaryum katkılı kompozitler, karmaşık geometrilere sahip hafif ve kurşunsuz radyasyon zırhlama malzemeleri için yüksek potansiyel sunmaktadır.

Investigation of Radiation Shielding Properties of Samarium Oxide Doped Photopolymer Composites for Additive Manufacturing Applications

Abstract

The need for cutting-edge and environmentally shielding materials to reduce radiation exposure has grown along with the use of nuclear energy due to scientific and industrial developments. The gamma attenuation characteristics of samarium oxide (Sm2O3)-doped photopolymer composites created for additive manufacturing applications are examined in this work. This study involved the theoretical design of resin structures that contained 0%, 10%, 20%, and 50% Sm2O3 by weight. The GAMOS Monte Carlo simulation code was used to examine the materials' radiation interaction parameters at gamma energies ranging from 81 keV to 1408 keV. The results showed that as the dopant concentration increased, the linear attenuation coefficient (LAC) and mass attenuation coefficient (MAC) increased significantly, while the half-value layer (HVL) thickness decreased. Specifically, at the low energy level of 81 keV, the Sm50 sample containing 50% Sm2O3 exhibited the highest radiation attenuation performance compared to the undoped sample. Consequently, samarium-doped composites produced using 3D printing technology offer high potential for lightweight and lead-free radiation shielding equipment with complex geometries.
