Scholarcy highlights

  • Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials
  • Mass attenuation coefficient and other derived parameters such as linear attenuation coefficient, atomic, total and electronic cross section, effective atomic number, electron density, half-value layer, and tenth value layer for few thermoplastic polymers with the help of NaI detector and WinXCom program revealed good agreement between experimental, theoretical, and simulated values of all parameters confirming the competency of the tested polymers in nuclear medicine gamma shielding
  • Iso-phthalate-based unsaturated polyester resin filled with different concentrations of lead monoxide particulate polymer composites was prepared for gamma rays of energy 0.662 meV from 137Cs point source, and linear attenuation coefficient was found to increase with increased filler content in the composites
  • The radiation shielding capabilities of a material depend on its material properties along with origin, type, energy, and exposure time of radiation, secondary radiations, and thickness of the material
  • The important disadvantages which limit its field of application and usage of lead and other conventionally used shielding materials have been covered
  • Nanostructure materials have recently concerned a lot of attention to scientists because of their potential applications in the development of several new technologies
  • One of the most applications is the radiation shielding materials which diminishes the hazard humans’ dosage by interacting with gamma-ray radiations and decreasing its power
