RF Waves and Shielding for MRI Applications - October 1, 2019

Previous posts that I have written have mostly dealt with shielding gamma and neutron radiation,however there are other forms of radiation that should be shielded in certain situation. Radio Frequency (RF) waves are a form of electromagnetic waves produced by electronic devices and networks such as cell phones or radio towers. These waves can cause interference with other sensitive electronic devices. RF and electromagnetic waves can be shielded by enclosing an area with conductive material and electronically grounding the shield. This is also commonly known as a Faraday Cage. The effectiveness of the shield will depend on the material used, thickness of the material, and what frequency the waves that need to shield are.
