متن کاملProperties of a Some (Ag-Cu-Sn) Alloys for Shielding Against Gamma Rays
The study of radiation absorption in material is an important subject to protect living creatures and environment from harmful effect of radiation. The degree to which gamma radiation is attenuated is dependent upon the energy of the incident gamma radiation, the thickness of the shielding, the atomic number and density of the elements in the shielding material. In this respect, this study pres...
متن کاملAssessment of polymer composite reinforced with nanomaterial against ionizing radiation
Introduction: Unwanted exposure of ionizing radiation may result in carcinogenesis, cell mutations, and organ failure. High-atomic number elements such as lead, tungsten, bismuth have been traditionally used for radiation protection. Theoretical and practical studies have shown that a variety of shielding materials e.g. polymer composites (PCs) can be used for attenuation of th...
