Abstract

In this manuscript is calculated the experimental and theoretical mass attenuation coefficient some K and Ca compounds by using transmission method. Also the total electronic cross section, atomic cross section, effective atomic number, effective electron density and Kerma parameters were obtanied using the calculated mass attenuation coefficient data. These radiaton attenuation parameters were obtained using the values calculated attenuation with the narrow beam experimental geometry. In this study, measurements were made using a high resolution Si (Li) detector at 59,543 keV from the Am-241 source. The theoretical mass attenuation coefficient were calculated from the WinXCOM data programme. The current study involves the gamma attenuation properties of selected compounds. The gamma attenuation parameters are studied in detail for all selected compounds.

Abstract

Bu yazıda deneysel ve teorik olarak bazı K ve Ca bileşiklerinin kütle soğurma katsayısı geçirgenlik yöntemi kullanılarak hesaplanmıştır. Ayrıca kütle soğurma katsayısı kullanılarak toplam elektronik tesir kesit, toplam atomik kesit, etkin atom numarası, etkin elektron yoğunluğu ve Kerma belirlendi. Bu soğurma parametreleri direkt geçirgenlik deney geometrisi kullanarak elde edildi. Bazı K ve Ca bileşiklerinin kütle soğurma katsayıları, Am-241 kaynağından 59.543 keV'de yüksek çözünürlüklü bir Si (Li) detektörü kullanılarak dar bir ışın iyi geometrisinde ölçüldü. Teorik kütle soğurma katsayısı değerleri, karışım kuralına dayalı XCOM programı ile belirlendi. K ve Ca bileşiklerinin kütle soğurma katsayısı, Zeff and Neff sonuçları gama koruyucu malzeme olarak nasıl davrandığı incelenmiştir.
