According to FDA guidelines, the maximum exposure to magnetic fields for adults and infants over 1 month of age is:

The correct answer is based on the guidelines established by the FDA regarding the safe exposure levels to magnetic fields, particularly in the context of magnetic resonance imaging (MRI). According to these guidelines, the maximum allowable magnetic field strength for adults and infants over 1 month of age is set at 8 Tesla (T).

This limit is important for ensuring the safety and well-being of patients during MRI procedures. Exposure to magnetic fields above this threshold could potentially pose risks due to the physiological effects of strong magnetic fields on the body, including effects on the heart, nervous system, and possibly other biological systems.

Understanding the regulatory framework and adherence to safety standards is crucial for Magnetic Resonance Safety Officers since they play a key role in ensuring that MRI practices prioritize patient safety. This guideline helps to mitigate risks associated with strong magnetic fields during imaging procedures.
