Polymer composite could serve as lighter, non-toxic radiation shielding

A new study from researchers at North Carolina State University suggests that a material consisting of a polymer compound embedded with bismuth trioxide particles holds tremendous potential for replacing conventional radiation shielding materials, such as lead.  The bismuth trioxide compound is lightweight, effective at shielding against ionizing radiation such as gamma rays, and can be manufactured quickly -- making it a promising material for use in applications such as space exploration, medical imaging and radiation therapy.  Read more.....
