摘要
A shielded room is constructed with walls having one shell made of electrically conductive facing sheets that prevent penetration of electromagnetic energy into the room, and two shells made of high magnetic permeability facing sheets that prevent penetration of magnetic fields into the room, one within the electrically conductive sheet and one outside the electrically conductive sheet. The edges of the conductive facing sheets are sealed to each other against leakage of electromagnetic energy with a joint compound made of a mixture of electrically conductive metallic particles in a flowable viscous base that enhances the electrical conductivity across the joint and excludes air from the sealed region. To prevent deterioration, the edges of the high magnetic permeability facing sheets are sealed to each other against leakage of magnetic fields with a joint compound made of a mixture of a high magnetic permeability material in a flowable viscous base that enhances the "magnetic conductivity" of the joint and excludes air from the sealed region.
