Aloe vera-mediated green synthesis of bismuth-zinc-iron nanocomposite for radiation shielding applications

Flexible, chemically bonded bismuth/tungsten‐based polyvinyl alcohol‐polyvinyl pyrrolidone composite for gamma and neutron shielding application

“…3,12 Conventionally, high Z metals like lead, barium, tungsten, bismuth, gadolinium, and their composites, and concretes are used. [12][13][14] But they are either quite heavy, toxic, rigid, lack of flexibility, and chemical stability. 3 Neutrons are electrically neutral particles and can easily travel through an electromagnetic medium or electron cloud in an atom without any interaction.…”
