Çalışmanın amacı: Bu çalışma, emprenye edilmiş karaçam (Pinus nigra Arnold subsp. pallasiana) odununun radyasyon zırhlama özelliklerini lineer zayıflatma katsayısı, kütle zayıflatma katsayısı, yarı değer ve onuncu değer katman kalınlığını 5 keV'den 1000 keV'ye kadar farklı gama enerjilerinde ölçerek araştırmaktadır.
Materyal ve yöntem: Emprenye edilmiş ahşap malzemenin doğrusal zayıflatma katsayısı (1/cm), kütle zayıflatma katsayısı (cm2/g), yarı değer ve onuncu değer katman kalınlığı değerleri WinXCOM tabanlı Phy-X/PSD yazılımı kullanılarak 5 ile 1000 keV enerji aralığında hesaplanarak beton ile karşılaştırılmıştır.
Temel sonuçlar: Emprenyeli ahşabın lineer zayıflatma katsayısı ile kütle zayıflatma katsayısının foton enerjisi arttıkça azaldığı bulunmuştur. Ancak, emprenyeli ahşabın yarı değer kalınlığı ve onuncu değer kalınlığı foton enerjisi arttıkça artmıştır. Sonuç olarak, ahşabın radyasyon kalkanı özelliklerinin borik asit emprenyesi ile arttığı tespit edilmiştir.
Araştırma vurguları: Emprenyeli odunun radyasyonu zırhlama özellikleri, yüksek yoğunluğu ve bor elementi içeren kimyasal bileşimi nedeniyle çam odunundan daha yüksek çıkmıştır.

Aim of study: The present work is to investigate the radiation shielding properties of impregnated black pine (Pinus nigra Arnold subsp. pallasiana) wood material by measuring linear attenuations coefficient, mass attenuations coefficient, half value and tenth value layer thickness for different gamma energies from 5 keV to 1000 keV.
Material and methods: The values of linear attenuation coefficient (1/cm), mass attenuation coefficient (cm2/g), half value and tenth value layer thickness of impregnated wood material were calculated in energy range between 5 to 1000 keV using the WinXCOM based Phy-X/PSD software and compared with concrete.
Main results: It has been found that the linear attenuation coefficient and the mass attenuation coefficient of impregnated wood decrease as photon energy increases. But, half value layer and tenth value layer of impregnated wood increased as photon energy increased. As a result, it was found that the radiation shielding properties of wood increasing with boric acid impregnation.
Highlights: The radiation shielding properties of impregnated wood are higher than pine wood because of its high density and chemical composition, which contains boron elements.
