Abstract: Lightweight and rigid, leaded or lead-free integral radiation shielding structural compositions comprising two or more radiation attenuating elements or compounds thereof, selected for having compatible radiation attenuating characteristics, dispersed in a thermoplastic or thermoset resin. The radiation shielding structural compositions of the present invention can be used to functionally and structurally replace lead-lined structures in medical and industrial x-ray systems. The radiation shielding structural compositions of the present invention can also be formulated to minimize the density of the resulting structure.
