Lightweight Foam Metal Blocks Radiation, X-Rays

Jul-24-15 A foam metal able to block X-rays, gamma rays as well as withstand high impact collisions could offer a new source of radiation shielding.

In development at North Carolina State, the foam metal was originally created for use in transport applications. However, team leader Afsaneh Rabiei wanted to investigate further uses for the foam, and to that end designed a metal foam composite called “high-Z steel-steel,” which was made by incorporating hollow spheres of tungsten into a large amount of stainless steel. The new metal foam is able to block high and low gamma rays and neutron radiation, and came second only to lead in blocking X-rays.
