Shielding behaviors of some polymer and plastic materials for gamma-rays

Determination of Radiation Shielding Properties of Some Polymer and Plastic Materials against Gamma-Rays

“…It shows better attenuation than concrete for low energies and this finding is also supported by the results of Mann et al [8]. For the values above 100 keV, S4 has a better shielding effectiveness for gamma-rays.…”

Preparation and characterization of tungsten/epoxy composites for γ-rays radiation shielding

“…However, high Z elements may not be able to block all types of radiations, particularly the emissions of neutrons in space or nuclear laboratories. Also, they are restricted in some applications due to the heavy weight, bulky space, and toxicity (lead) [1][2][3]. Therefore, non-toxic ''lead-free'' filler-reinforced polymer composite for its lightweight, workability, and ability to effectively attenuate radiation has aroused great public interest in many areas, especially in medical treatment, nuclear plant and mobile nuclear devices.…”

PRINCIPLES OF DEGRADATION BY Γ-Radiation

“…The thermal expansion of the solid whose atoms/molecules are held by van der Waal's forces is about two orders of magnitude greater than that of a covalently bonded solid. 25 PVC was found to have the best shielding capabilities in the energy range from 10 to 110 keV. 22 Crystalline order in PVC is destroyed by irradiation.…”
