A shielded room is a modern protective facility specifically designed and constructed to prevent harm to the human body from radar microwave radiation. The enclosure is assembled from high-quality, cold-rolled galvanized steel modules and is equipped with an electromagnetic leakage-proof shielded door, specialized ventilation waveguide windows, and waveguide tubes for signal transmission and fire protection. The observation window is specially made by combining imported ultra-fine silver-plated copper mesh with cesium-potassium fire-resistant glass, providing excellent visibility. The microwave radiation leakage level from the shielded room fully complies with, and even exceeds, national public exposure limits, effectively protecting personnel working or visiting nearby.
Overview of National Standards for Shielded Rooms:
Shielded rooms are constructed from magnetic materials. The parameter measuring a material's ability to conduct magnetic flux is permeability—the higher the permeability, the better the shielding effect. Commonly used high-permeability materials include cold-rolled steel sheets, and the thickness of the shielding material is decisive. The stronger the magnetic field, the greater the required thickness of the shielding material.
