Shielding Property of Closed-Cell AlSi7 Foams and AlSi7 Bulk Materials against Gamma Rays

Bu çalışmanın amacı kapalı gözenekli AlSi7 köpükler ile AlSi7 bulk malzemelerin gama ışınlarına karşı zırhlama özelliklerinin deneysel olarak karşılaştırılmasıdır. Bu malzemeler toz metalurjisi yöntemi ile üretilmiştir. Gama ışınları zayıflatma ölçümleri 88, 511, 662, 1173, 1275 ve 1332.5 keV foton enerjilerinde gerçekleştirilmiştir. Elde edilen sonuçlar AlSi7 bulk malzemelerin kapalı gözenekli AlSi7 köpüklere kıyasla daha iyi gama ışını zayıflatma yeterliliğine sahip olduğunu göstermektedir. Bunun nedeni ise bulk malzemelerin köpüklere kıyasla daha yüksek yoğunluğa sahip olmalarıdır.

Kapalı Gözenekli AlSi7 Köpükler ve AlSi7 Bulk Malzemelerin Gama Işınlarına Karşı Zırhlama Özelliği

The aim of this paper is experimental comparison of shielding properties against gamma rays among closed-cell AlSi7 foams and bulk materials. These materials were produced by powder metallurgy method. Gamma rays attenuation measurements were performed at photon energies of 88, 511, 662, 1173, 1275 and 1332.5 keV. The obtained results revealed that AlSi7 bulk materials offer better gamma rays attenuation capabilities due to their high density compared to closed-cell AlSi7 foams.
