Resin based tungsten sheet-Environment-friendly lead alternative material
Kenji OKAMURA, Yasunao KAI
Key words radiation shielding, lead alternative material, high specific gravity, flexibility, composite materials, tungsten, resin


Lead used for radiation shielding is harmful to human body so an alternative material has been required recently. Therefore, we developed a high specific gravity tungsten sheet that is made of composite materials of resin and tungsten that can replace lead. Since the resin-tungsten sheet is manufactured using an original process it is flexible and has equivalent or even higher radiation shielding ability than lead.
