Access to Zone III is restricted specifically to whom?

Access to Zone III, which is the area immediately outside the magnet room in an MRI facility, is restricted to MR personnel because it is considered a controlled access area. MR personnel are specifically trained to understand the safety protocols related to the intense magnetic fields and radiofrequency energy present in this environment. They are aware of the risks associated with the presence of metal objects, the operation of MRI machinery, and the proper procedures for dealing with emergencies that may arise in this zone.

This restriction helps to ensure the safety of those who may be unaware of the hazards present in the MRI setting, such as patients, visitors, or the general public, who may not have the necessary training to navigate the risks associated with an MRI suite safely. By limiting access to only those who are qualified, the facility helps prevent accidents, ensures compliance with safety regulations, and maintains a secure environment for both staff and patients undergoing MRI procedures.
