In the current study shielding parameters, the mass and linear attenuation coefficients, and half value layer (HVL), tenth value layer (TVL) and mean free path (MFP) values were calculated theoretically used the calculation software Phy-X/PSD for superconducting lead free SnIn alloy solder system that the alloy composition were chosen from the binary phase diagram of SnIn and PbSn which has been mostly used solder alloy for in micro electric and cryogenic applications for decades. The results showed that among the studied sample increasing tin content decreases the shielding efficiency and Sn 20 In 80 system shows better shielding properties depend on the used energy. Thus, it needs to be considered the energy range to determine the thickness of the material subjected to the gamma radiation as the shielding parameters change depend on using energy

The harmful effects of radiation on human health have long been recognized. These effects include radiation burns, radiation diseases, shortening of life span, cancer and hereditary disorders. Therefore, the absorption properties and applicability of the material used in radiation shielding are very important. Hence, studies are underway on the development of different types of shielding materials. In this study, radiation absorption properties of lead (II) nitrate Pb(NO3)2 coated wall papers were investigated. The wall papers in different densities (100% precipitated calcium carbonate (PCC), 2.5 g, 5 g, and 7.5 g amounts of Pb(NO3)2) and various thicknesses (0.176-0.236 mm) were prepared and investigated. 4 MeV-energized electrons were applied to the Pb(NO3)2 coated wall papers and measurements were taken with the PTW brand electron detector. Also, theoretical calculations have been done by using WinXCom program. According to the obtained results, these wallpapers' absorption properties increased depending on thickness. Thus, it has been seen that the Pb(NO3)2 coated wallpapers can be used with other materials in radiation shielding. ÖzRadyasyonun insan sağlığı üzerindeki zararlı etkileri uzun zamandır bilinmektedir. Bu etkiler radyasyon yanıkları, radyasyon hastalıkları, yaşam süresinin kısalması, kanser ve kalıtsal bozuklukları içerir. Bu nedenle, radyasyon zırhlamada kullanılan malzemenin soğurma özellikleri ve uygulanabilirliği çok önemlidir. Bu nedenle, farklı koruyucu malzemelerin geliştirilmesi üzerine çalışmalar devam etmektedir. Bu çalışmada kurşun(II) nitrat Pb(NO3)2 kaplamalı duvar kâğıtlarının radyasyon soğurma özellikleri araştırılmıştır. Farklı yoğunluklarda (%100 çökeltilmiş kalsiyum karbonat (PCC), 2.5 g, 5 g ve 7.5 g Pb(NO3)2) ve çeşitli kalınlıklarda (0.176-0.236 mm) duvar kağıtları hazırlandı ve araştırıldı. Pb(NO3)2 kaplanmış kağıtlara 4 MeV-enerjili elektron uygulandı ve PTW marka elektron detektörü ile ölçümler alındı. Ayrıca, WinXCom programı kullanılarak teorik hesaplamalar yapıldı. Elde edilen sonuçlara göre, bu duvar kâğıtlarının soğurma özellikleri kalınlığa bağlı olarak artmıştır. Böylece, Pb(NO3)2 kaplı duvar kağıtlarının diğer malzemelerle birlikte radyasyon zırhlamada kullanılabileceği görülmüştür.Anahtar kelimeler: Radyasyon, zırhlama, duvar kâğıdı, kurşun (II) nitrat. * Sorumlu yazar:

This article presents data collected by measurements of lead (Pb) and iron (Fe) and their combination as heavy shielding materials. Measurements were performed using gamma photon energies of 662, 1173, and 1332keV for the Cs-137 and Co-60 sources. The theoretical data part was calculated using WinXCom, Phy-X, and Py-MLUBF software packages. Tables and graphs of the photon Mass Attenuation Coefficient (MAC), Linear Attenuation Coefficient (LAC), Half Value Layer (HVL), Tenth Value Layer (TVL) and Mean Free Path (MFP) are presented for both heavy metals and their combination to study the shielding properties experimentally and theoretically. The results will contribute to the ongoing research as a database for future use.
