“…The Pb-Sn alloys of various compositions, soldering material, Bakelite, Perspex, bronze, brass and scientific samples of rare earths materials were investigated to study the effective atomic number in a scattering geometry [6]. Several investigations [7][8][9][10] had determined the parameters like mass attenuation coefficient, effective atomic number, electron density, half value layer (HVL), tenth value layer (TVL), atomic and electronic cross-sections, and mass energy absorption coefficients.…”

Mass attenuation coefficient is a fundamental parameter of radiation interaction, from which the other radiological parameters like half Value Layer [HVL], tenth Value Layer [TVL], total atomic and electronic cross-sections, mass energy absorption coefficient, KERMA, CT number and effective atomic number are deduced. These parameters are extensively required in a number of fields such as diagnostic radiology, gamma ray spectroscopy, fluorescence analysis and reactor shielding. In the present work, mass attenuation coefficients are determined experimentally for some organic compounds at 122 keV incident photons using narrow-beam transmission geometry to establish a relation between effective atomic number (Z eff) and other deduced parameters. The experimental data for all these parameters are compared with the values deduced from WinXcom software package and are found to agree within experimental estimated errors. This study gives some insight about the photon interaction in some organic compounds whose effective atomic numbers match with some human body fluids.

Radyasyon kullanımı tıp, sanayi, tarım ve nükleer santraller alanında günden güne artarak gelişmeye devam etmektedir. Bu alanlardaki iş kollarında çalışanların ve halkın radyasyonun zararlı etkilerinden korunması, nükleer teknolojilerin gelişiminin yanı sıra oldukça önemli başka bir konudur. Bu çalışmada, kimya laboratuvarımızda sentezlenen bazı hekzaborürler (LaB6 ve CeB6) X–ışını kırınımı (XRD) ile analiz edilmiş, Debye Scherrer eşitliği ile ortalama kristal boyutları hesap edilmiş, nano boyutta oldukları görülmüş ve bu numunelerin gama ışını zırhlama özellikleri incelenmiştir. Gama ışını koruma parametreleri olarak; kütle zayıflatma katsayıları, yarı değer katmanı, onda bir değer katmanı, ortalama serbest yol, etkin atom numarası, etkin elektron yoğunluğu, toplam atomik kesit ve toplam elektronik kesit değerleri, Monte Carlo yöntemi ile belirlendi. Bu yöntemde kullanılan foton enerji aralığı, 1.0 keV - 105 MeV olup, elde edilen veriler XCom programı tarafından hesaplanan sonuçlarla karşılaştırıldı. MC ve XCom arasında hesaplanan sonuçlar, radyasyon koruyucu malzemeler olarak kurşun, vermikülit, borosilikat, beton ve granit ile karşılaştırıldığında başarılı bir tutarlılık göstermiştir. Üretilen hekzaboridlerin, literatürde daha önce araştırılan malzemelere kıyasla daha umut verici gama koruma özelliklerine sahip olduğu sonucuna varılmıştır.

“…And the studies have experimental and/or theoretical values and can show radiation shielding properties of the materials. They can also explain linear attenuation coefficient (cm -1 , µ, LAC), mass attenuation coefficient (cm 2 .gr -1 , µ m , MAC), mean free path (cm, MFP), half values of layer (cm, HVL), tenth values of layer (cm, TVL), effective atomic number (Z eff ), effective electron density (N eff ) and buildup factors for steels [3][4][5][6][7][8][9][10][11][12][13][14]. Alım et al [15] have recently determined radiation parameters of AISI-coded stainless steels (Part 1) both experimentally and theoretically at different photon energies.…”

In this study, S235JR (1.0037), 21NiCrMo2 (1.6523), C45 (1.0503), 42CrMo4 (1.7225) steels were coated with nickel, copper, silver, and tin. Then, the radiation shielding performances of the uncoated and coated steels were investigated. The steels were firstly designed by the coating processes via electrolytic plating method on behalf of Ni, Cu, Ag and Sn metals. The samples were then irradiated by radioactive sources for transmission of the gamma rays at photon energies in the range 81-383 keV photon energies to measure linear and mass attenuation coefficients (LAC-µ, MAC-µ/) of the pure and coated steels by Ni, Cu, Ag and Sn. Half and tenth value of layers (HVL and TVL) of investigated materials were then calculated at the same studied photon energies. The materials were compared with each other as well as with some shielding concretes in terms of mean free paths (MFP) wherever possible. The coated steels were found to be better shielding materials than the concretes due to lower MFP values they had, and they showed also better shielding than reference materials up to 35.31% relative difference in MFP. It was concluded that coating processes improved the shielding properties of the steels.
