“…Due to the diversity of physical properties of the 3d transition elements, many applications of these elements and their compounds indicate the need to get information about various physical parameters [19]. Many studies have been done about coefficients, 𝑍 𝑒𝑓𝑓 of the 3d transition metal elements, their compounds and alloys at several photon energies before [19][20][21][22][23]. But these works are limited only by some parameters in several energies.…”

“…In this work, it is aimed to calculate radiation attenuation parameters of some compounds of the 3d transition elements (CoO, CoF2, CoF3, Cr2O3, CrF2, CrF3, FeO, Fe2O3, MnO2, TiO2, V2O3, VF3, V2O5, VF4 and ZnO) in the photon energy range of 0.01-15 MeV theoretically by using Phy-X/PSD software which can calculate quickly and accurately all specified shielding parameters for different materials in the continuous energy range and selected energies [10]. At 19.63 and 22.10 keV energies, calculated MAC and 𝑍 𝑒𝑓𝑓 values of the compounds were also compared with the experimental MAC and 𝑍 𝑒𝑓𝑓 results given by Yılmaz et al, [23].…”

In the present study, it was aimed to calculate the radiation-matter interaction parameters of some compounds of 3d transition elements. The radiation attenuation parameters, which are important to have knowledge about the radiation shielding potentials, were calculated by using Phy-X/PSD code in the energy range of 0.01-15 MeV. The calculated mass attenuation coefficient and effective atomic number results were compared with the experimental data which were measured at 19.63 and 22.10 keV previously and, a good agreement was achieved. In order to evaluate the shielding properties of the compounds, we also compared the mass attenuation coefficients of the compounds with ordinary concrete, steel-scrap, ilmenite-limonite and basalt-magnetite, which are widely used as radiation protective materials. According to the obtained results, it is concluded that the studied compounds have radiation shielding potentials.

Due to their excellent features and applications, hydrogels become so popular and are used for fabricating contact lenses, cancer treatment, hygiene products, tissue engineering, drug and delivery systems. Simultaneously use of hydrogels with radiotherapy is known to be effective in protecting the healthy cells from high radiation. From this point on, it is necessary to know radiation attenuation properties of compounds used in production of hydrogel. In the present study, half value layer (HVL), effective atomic number (Zeff), effective electron density (Nel) and energy absorption and exposure buildup factors (EABF and EBF) of eight hydrogel samples (hyaluronic acid, chitosan, fibrin, dextran sulfate, pectin, alginic acid, chondroitin sulfate and carrageenan) have been investigated. From the obtained results, it might be concluded that these parameters depend on the elemental composition of the samples. It is seen that dextran sulfate has most superior radiation absorption capacity while fibrin has the lowest when compared to other samples.Abstract: Mükemmel özellikleri ve uygulamaları nedeniyle, hidrojeller son derece popülerdir ve kontakt lenslerin üretimi, kanser tedavisi, hijyen ürünleri, doku mühendisliği ve ilaç verme sistemleri için kullanılır. Hidrojellerin radyoterapi ile eş zamanlı kullanımının, sağlıklı hücrelerin yüksek radyasyondan korunmasında etkili olduğu bilinmektedir. Bu noktadan hareketle, hidrojel üretiminde kullanılan bileşikerin radyasyon azaltma özelliklerini bilmek gereklidir. Bu çalışmada, sekiz hidrojel örneğinin (aljinik asit, hiyalüronik asit, kitosan, fibrin, carrageenan, pektin, kondroitin sülfat ve dekstran sülfat ) yarı değer kalınlığı (HVL), etkin atom numarası (Zeff), etkin elektron yoğunluğu (Nel) ve enerji absorpsiyon ve maruz kalma kuvvetlendirme faktörleri (EABF ve EBF) incelendi. Elde edilen sonuçlara göre, bu parametreler, numunelerin elementel kompozisyonuna bağlı olup, diğer örnekler ile kıyaslandığında dekstran sülfatın daha üstün radyasyon soğurma kapasitesine sahipken fibrinin en az olduğu görülebilir.

In the present study, the optical characterization of borate glasses with composition 35Li 2 O − 10ZnO − 55B 2 O 3 − xMnO 2 : x = 0, 0.5, 1.0, 1.5, and 2.0 wt% has been investigated. The absorption spectra measurements within the wavelength domain 200-1000 nm have been carried out. The optical energy gap of the investigated samples using the absorption spectrum fitting (ASF) model has been calculated. The molar refraction, molar polarizability, reflection loss, optical transmission for the samples were estimated. The metallization criterion, dielectric constant, refractive index, and energy band metallization criterion for the studied glasses were estimated. Magnetic property measurements for all glass samples were carried out at 300 K. Additionally, the prospects of gamma-ray interactions with the investigated glasses have been achieved through studying the total mass attenuation, coherent, Compton, photoelectric, and pair production interactions at photon energy in the range of 0.356-1.330 MeV. Results reveal that the optical and magnetic properties of the investigated glasses change with changing the MnO 2 concentration. Studied glasses can be used as a candidate for optical fiber and optical devices application. In the other hand, at lower gamma photon energy range, the photoelectric absorption dominates with the glasses, while as the energy increases, the probability of Compton scattering and pair production become the most dominate interactions.
