Bu çalışmada, manyetik kalkan alaşımları olarak bilinen Ni80Fe15Mo5 ve Ni77Fe14Cu5Mo4’ün foton-madde etkileşim parametrelerini hesaplamayı amaçladık. Parametreler Phy-X / PSD yazılımı kullanılarak belirlendi. Alaşımların 15keV ve 100GeV foton enerjileri arasında radyasyon zırhlama potensiyellerinin belirlenmesi için kütle zayıflatma katsayısı, doğrusal zayıflatma katsayısı, efektif atom numarası, yarı kalınlık değeri, onda birine düşürme değeri, toplam atomik tesir kesiti ve toplam elektronik tesir kesiti gibi radyasyon zayıflatma parametreleri hesaplanmıştır. Alaşımların zırhlama potansiyelleri, daha önce bildirilmiş yaygın olarak kullanılan zırhlama malzemelerinin potansiyelleriyle karşılaştırılmıştır.

A Theoretical Study on Radiation Shielding Characteristics of Magnetic Shielding Alloys, Ni80Fe15Mo5 and Ni77Fe14Cu5Mo4, by Determining the Photon Attenuation Parameters in the Energy Range of 15keV-100GeV

In this study, we aimed to calculate photon-matter interaction parameters of Ni80Fe15Mo5 and Ni77Fe14Cu5Mo4, which are known as magnetic shielding alloys. The parameters were determined by using Phy-X/PSD software. The radiation attenuation parameters such as mass attenuation coefficient, linear attenuation coefficient, effective atomic number, half-value layer, tenth-value layer, total atomic cross section and total electronic cross section were calculated between the photon energies 15keV and 100GeV in order to determine the radiation shielding potentials of the alloys. The shielding potentials of the alloys were compared with those of widely used shielding materials reported before.
