Summary: In this study, the photon attenuation properties of glasses with different chemical compositions were experimentally tested using an HPGe detector and multiradioactive point source. The practical findings matched the theoretical results well, showing that the linear attenuation coefficient can be used to assess photon protection efficacy and other related parameters. The PCNKPb20 glass was found to be highly effective in blocking low-energy radiation.

Summary: With the increasing usage of electronic gadgets, Electromagnetic (EM) pollution has become a pressing concern. A lightweight and flexible shield is in huge demand to comply with modern electronics. In this study, designer core-shell porous nanospheres (PNSs) are synthesized, and their composites with multiwalled carbon nanotubes (MWCNTs) are developed in ethylene-vinyl acetate (EVA) with excellent EM interference (EMI) shielding ability. The as-prepared Fe3O4 PNSs are coated with Ag by electroless deposition to enhance their effectiveness.

Summary: Continuous exposure to low-level scattered radiation is a concern for staff performing cardiac angiography and intervention. A novel shielding solution (NSS) has shown greater effectiveness in reducing radiation dose compared to a traditional shielding solution (TSS). The NSS significantly decreased radiation dose to operators and scrub nurses at various body locations, while maintaining a dose of 0.0 mSv at the under-apron location.
