A radiation protection device consisting of electrically conductive materials used in conjunction with other medical devices in a medical facility to form a barrier against radio-frequency (RF) emissions and interference. This kind of material protects medical devices and/or persons from incident or stray radio-frequency fields. This group of devices includes a wide variety of materials, e.g., copper (Cu) sheeting and copper mesh. Copper sheets and copper mesh are used in walls, floors, ceiling, doors and windows for magnetic resonance imaging rooms to prevent interference with the electronics used to form and receive the radio-frequency imaging pulses.
