Abstract
This investigation focuses on the gamma ray attenuation parameters of natural animal bone, iron, cobalt, copper and zinc doped Nano hydroxyapatite artificial bone powders and pure hydroxyapatite. The present specimens were excited by means of gamma ray photons with 59.5 keV energy radiated from a 241-Amercium annular radioactive source with 50 mCi activity by means of narrow beam transmission geometry. The transmitted gamma-rays were counted with using Ultra Low Energy Germanium (Ultra-LEGe) detector with a resolution 150 eV at 5.95 keV. The gamma-ray attenuation characteristics such as mass attenuation coefficient (MAC) (µ/ρ), linear attenuation coefficient (LAC) (µ), half value layer (HVL), tenth value layer (TVL) and mean free path (MFP), which has a significant role in the attenuation studies, are also calculated. The values obtained were checked with the predicted values from the XCOM NIST. The results show that the attenuation data of the metal-doped hydroxyapatite synthetic bone dust is very close to the value of the natural animal bone.

Abstract
Bu araştırma, doğal hayvan kemiği, demir (Fe), kobalt (Co), bakır (Cu) ve çinko (Zn) katkılı Nano hidroksiapatit yapay kemik tozları ve saf hidroksiapatitin gama ışını soğurma parametrelerine odaklanmaktadır. Mevcut örnekler, dar bir ışın iletim geometrisi kullanarak 50 mCi aktivitesine sahip 241-Amercium radyoaktif halka şeklindeki bir kaynaktan yayılan 59.5 keV enerjili gama ışını fotonları vasıtasıyla uyarıldı. Numuneden geçen gama ışınları deneysel olarak 5.95 keV'da 150 eV çözünürlüğe sahip Ultra Düşük Enerji Germanyum (Ultra-LEGe) detektörü kullanılarak sayıldı. Kütle soğurma katsayısı (µ / ρ), doğrusal soğurma katsayısı (µ), yarı değer katmanı (HVL), onuncu değer katmanı (TVL) ve soğurma çalışmalarında önemli bir role sahip olan ortalama serbest yol (MFP) gibi gama ışını soğurma özellikleri hesaplandı. Elde edilen değerler, XCOM NIST'ten tahmin edilen değerlerle kontrol edildi. Sonuçlar, metal katkılı hidroksiapatit sentetik kemik tozunun gama ışını soğurma verilerinin, doğal hayvan kemiğinin değerine çok yakın olduğunu göstermektedir.
