Envirotect Limited are proud to announce our latest product release of RF Shielding and Magnetic Interference Shielding for MRI Scanners (Magnetic Resonance Imaging) to complement an already successful range of Radiation Shielding products. RF Shielding is required to block out specific radio waves from outside the scanner room because these will distort the images created by the MRI Scanner. This is achieved by forming an electrically sealed 6 sided box, i.e. floor, ceiling, walls, control window, entrance door as well as service penetrations. This differs from radiation shielding where the lead shielding is to prevent the radiation leaking from the scanner room and exposing staff, patients and the public to its harmful effects. The RF Shielding system provides RF attenuation levels > 100dB up to MRI frequencies of 400MHz. Generally MRI systems range from 0.2 Tesla to 3.0 Tesla, however there are research magnets that have much higher field strengths.
