Angular width of a narrow beam for X-ray linear attenuation coefficient measurements
The detection of scattered radiation can be a major source of systematic errors when measuring the X-ray linear attenuation coefficient, m. Angular distributions of scattered photons are studied for Z 1⁄4 1 to 20 at energies 6 keV to 100MeV, using tabulated atomic form factors and incoherent scattering functions. A circularly symmetric pencil beam irradiation geometry is considered, and scatter...
متن کاملRadiation attenuation properties of shields containing micro and Nano WO3 in diagnostic X-ray energy range
Background: It has recently been shown that the particle size of materials used for radiation shielding can affect the magnitude of radiation attenuation. Over the past years, application of nano-structured materials in radiation shielding has attracted attention world-wide. The purpose of this study was to investigate the shielding properties of the lead-free shields containing micro and nano-...
متن کاملInvestigation of the Mass Attenuation Coefficient for Composites Containing Nano and Micro-Particles of Copper Oxide against Diagnostic X-ray
Radiation protection and the selection of suitable materials to reduce radiation effects is one of the important branches of medical science and radiation. In this paper, the mass attenuation coefficients, half value layer thicknesses and thicknesses of 0/5 mm lead of polyvinyl chloride (PVC) composites containing Nano and micro-particles of copper oxide are calculated using experimental method...
متن کاملEvaluation of multifunctional targeted gold nanoparticles on X-ray attenuation in nasopharyngeal cancer cells by X- ray imaging
Introduction: Head-and-neck cancer is the sixth most common cancer worldwide with the number of cases consistently increasing in developing countries. Successful development of effective, safe and cost effective nanoprobes for head-and-neck cancer targeting imaging is a big challenge. This study is aimed to develop cysteamine-folate conjugated gold nanoparticles (F-Cys-AuNPs) a...
