An air-permeable, electromagnetic radiation-shielding panel comprising metallized textile mounted in a conductive frame for providing electromagnetic radiation shielding of air flow apertures in the walls of an architecturally shielded facility. Preferred metallized textile has an air permeability at a pressure drop of 12.7 mm of water of at least 254 cm3/cm2-sec and exhibits far field shielding of electromagnetic radiation of at least 50 dB over the range of 0.1 to 10 gigahertz. The frame is adapted to be seated in an air flow aperture in a radiation shielding wall covering, comprises a conductive surface, is adapted to secure the edges of the textile and provide electrical contact between the textile and the radiation shielding wall covering. |
