Nuclear Structure and Galactic γ-Ray Activity
The observation of galactic γ lines following the decay of radioactive nuclei provides a direct link between nuclear physics experiments in earth-based laboratories and astrophysical observations with space-based observatories. Two examples are presented to illustrate this interplay: the measurement of the lifetime of (44)Ti to allow an improved determination of the (44)Ti mass of the supernova...
متن کاملStudy of gamma rays shielding parameters of some building materials used in Sudan
Background: This study investigated the γ-rays shielding properties of some building materials in Sudan has been investigated. Materials and Methods: Photons attenuation coefficients and half value layer (HVL) were experimented using Cs-137 and Co-60 sources. The measurements were performed to gauge the intensity of radiation when performed unshielded, the specific thickness of selected sample...
متن کاملA review on neutron shielding performance of nano-composite materials
Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...
متن کاملPolymethylmethacrylate/Silver Nanocomposite Prepared by γ-Ray
Polymethylmethacrylate-silver (PMMA/Ag) nanocomposite is synthesized by irradiating the solution of silver ions in methylmethacrylate monomer by γ-ray. In this method, polymerization of the methylmethacrylate monomer and the silver ion reduction occurred simultaneously. Optical properties of the PMMA/Ag solutions are investigated using UV-Vis spectroscopy. The structural characterizations of th...
متن کاملEvaluation of lead equivalence of patient and hardware materials in medical diagnostic x-ray shielding.
In the estimation of additional shielding requirements for primary beam apart from that provided by patient and hardware in the x-ray beam, there is the need to distinguish between attenuation and hardening properties of materials in comparison. In this work, numerical comparison of attenuation and hardening properties of phantom (Lucite, soft tissue, water) and hardware (aluminum and steel) ma...
