Özet:

 In this study, radiation shielding properties of 8 different wood species T1T8 were investigated experimentally and theoretically using the XCOM program. The densities and elemental compositions of the samples were determined by EDAX analysis, and a NaI Tl detector was used in gamma spectroscopy experiments performed at energy levels of 662 keV, 1173 keV and 1332 keV. Strong correlations were observed between the linear attenuation coefficient LAC obtained from the experimental data and the density; this relationship was particularly evident at 662 keV R²  0.9195, slope  0.0792. The highest mass attenuation coefficient MAC values were determined as 0.085 at 662 keV in samples T3, T4 and T5. On the other hand, the lowest MAC values were observed in sample T1 between 0.0450.060. The half-value layer HVL values increased with energy; Sample T1 had the highest HVL at all energies, reaching approximately 125 mm at 1173 keV. HVL values for species such as T4 and T5 remained in the range of 1030 mm. Similarly, the tenth value layer TVL and mean free path MFP values were measured at the highest levels for T1; at 1332 keV, TVL reached approximately 420 mm and MFP reached 180 mm. These values were lower for other wood species. The theoretical MAC values obtained with the XCOM program were found to be in very good agreement with the experimental data R²  0.98. These results demonstrated that high-density wood species provide more effective attenuation against low-energy gamma photons and that the XCOM program is a reliable tool for the radiation protection analysis of wood materials.

 Bu çalışmada, 8 farklı ağaç türünün T1T8 radyasyon zayıflatma özellikleri deneysel olarak ve XCOM programı kullanılarak teorik olarak incelenmiştir. Numunelerin yoğunlukları ile elementel bileşimleri EDAX analizi ile belirlenmiş, 662 keV, 1173 keV ve 1332 keV enerji seviyelerinde gerçekleştirilen gamma spektroskopisi deneylerinde NaI Tl dedektörü kullanılmıştır. Deneysel verilerden elde edilen lineer zayıflama katsayısı LAC ile yoğunluk arasında güçlü korelasyonlar gözlenmiş, özellikle 662 keVde bu ilişki oldukça belirgindir R²0.9195, eğim  0.0792. En yüksek kütle soğurma katsayısı MAC değerleri 662 keV enerjisinde T3, T4 ve T5 numunelerinde 0.085 olarak belirlenmiştir. Buna karşılık en düşük MAC değerleri T1 numunesinde 0.0450.060 arası gözlenmiştir. Yarı değer tabakası HVL değerleri enerjiyle birlikte artış göstermiş; T1 numunesi tüm enerjilerde en yüksek HVLye sahip olup, 1173 keVde yaklaşık 125 mmye ulaşmıştır. T4 ve T5 gibi türlerde HVL değerleri 1030 mm aralığında kalmıştır. Onda bir değer tabakası TVL ve ortalama serbest yol MFP değerleri de benzer şekilde T1 için en yüksek seviyelerde ölçülmüş; 1332 keVde TVL yaklaşık 420 mm, MFP ise 180 mmye ulaşmıştır. Diğer ağaç türlerinde bu değerler daha düşük kalmıştır. XCOM programı ile elde edilen teorik MAC değerleri ile deneysel veriler arasında oldukça yüksek uyum bulunmuştur R²0.98. Bu sonuçlar, yüksek yoğunluklu ağaç türlerinin düşük enerjili gamma fotonlarına karşı daha etkin zayıflatma sağladığını ve XCOM programının ahşap malzemelerin radyasyon koruma analizinde güvenilir bir araç olduğunu ortaya koymuştur.
