Seryum ve Bazı Seçilmiş Seryum Bileşiklerinde Gama Radyasyonu Yansıtma Parametreleri

Bu çalışmada albedo parametreleri, hedef numuneler üzerine düşen elektromanyetik radyasyonun yansıtma kapasitesi olarak bilinir; yüzeyin yansıtma özelliği araştırıldı. Bu amaçla deney düzeneğinde radyoaktif kaynak olarak 241Am ve kaynaktan yayılan gama ışınlarını yansıtması nedeniyle saçılan fotonları saymak için yarı iletken dedektör kullanılmıştır. Deneyden elde edilen veriler, hedef numunelerin atom numarasına bağlı olarak çizildi. Sonuç olarak, bu çalışma, seçilen örneklerin albedo faktör parametrelerinin artan ortalama atom numarası ile azaldığını göstermektedir.

Gamma Radiation Reflection Parameters of Ce and Selected Ce Compounds

In this study, the albedo parameters are known as the reflectance capacity of the electromagnetic radiation falling on the target samples; the surface's reflectivity was investigated. For this purpose, in the experimental setup, 241Am as a radioactive source and a semiconductor detector were used to count the scattered photons due to reflecting the gamma rays radiating from the source. The data obtained from the experiment were plotted depending on the atomic number of the target samples. It is understood from this study that the albedo factor parameters of the target samples selected for research decrease with increasing average atomic number.
