Understanding the Effect of Introducing Micro- and Nanoparticle Bismuth Oxide (Bi2O3) on the Gamma Ray Shielding Performance of Novel Concrete

“…By multiplying the mass attenuation coefficient in the density ρ (g/cm 3 ), we obtain an essential parameter called the linear attenuation coefficient or LAC (cm −1 ), which measures the probability of photon interaction inside the material per unit path length. The half-value layer (HVL) and the tenth-value layer (TVL) values are important attenuating factors and are defined as the thickness needed to reduce the intensity of incident photon to half-and tenth-initial values, respectively, and can be calculated using the following relations [33].…”

Evaluation of the effects of bismuth oxide (Bi2O3) micro and nanoparticles on the mechanical, microstructural and γ-ray/neutron shielding properties of Portland cement pastes

“…Materials with high atomic number (High-Z) can be used to manufacture conventional blocks and multi-leaf collimators (MLCs) to form better beams and to reduce the absorbed dose in normal tissue. To date, lead (Pb) is the most commonly used material, due to its high atomic number (Z), low cost and abundance [4][5][6]. Interest in lead-free radiation shields has increased in recent years, since a great deal of concern has been voiced regarding the potential toxicity of lead and its compounds, both to humans and the environment as well as high costs for dismantling and disposal [7].…”

Ni Tabanlı Bazı Süperalaşımların Foton Etkileşim Özelliklerinin İncelenmesi

“…Canlıları iyonlaştırıcı radyasyonun zararlarından korumak için geleneksel zırh malzemesi olarak bilinen kurşun bloklar ve ağır agregalarla üretilen betonlar uzun yıllardır kullanılmaktadır [1,2]. Kurşunun toksik etkileri ve kurşun, beton blokların kullanımı açısından bazı dezavantajları sebebiyle araştırmacılar yeni zırh malzemelerine yönelmişlerdir [3,4].…”
