ARCHITECTURAL and MEDICAL SHIELDING
Architectural Shielding
Architectural shielding is the protection of buildings from electromagnetic fields using a range of suitable materials bonded directly to the host building. Careful consideration of shielding attenuation, frequency range and cost will dictate the most effective material and method of installation.
Commonly used materials include copper and aluminium foils, steel sheet, metallised fabrics and meshes in a variety of metals.
Careful design of the RF penetrations, such as the doors, electrical cables and air-conditioning vents is essential to ensure the maximum practical RF performance can be achieved.
EEP Ltd can offer a complete service from initial RF site surveys to design, installation and final attenuation testing.

Shielded rooms for Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is a sophisticated imaging system that provides high resolution images of the body without the use of ionising radiation. When a patient is placed in an MRI scanner, a powerful magnetic field causes all the protons in the body to align in the same direction. Radio Frequency (RF) pulses are then emitted by a gradient coil which cause the protons to deflect by varying degrees. This process results in the emission of an RF signal which is picked up by a receiver coil and converted into a digital internal image of the body.
The majority of MRI scanners need to be placed inside a Radio Frequency (RF) shielded room to prevent external interference affecting the signals that produce the final images.
EEP Limited are a world leader in the design and installation of RF shielded rooms for MRI scanners.
