What is the ICNIRP limit for the general public?

The correct limit for the general public as specified by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) pertains to the exposure to static magnetic fields. This limit is defined as 400mT (millitesla). This threshold is established to ensure that non-occupational exposure to magnetic fields does not result in adverse health effects for individuals who are not in a controlled work environment.

The rationale behind setting such limits is to protect the general public from both immediate and long-term effects of exposure to magnetic fields, especially since these fields can influence the functioning of biomedical implants and other electronic devices. In the context of magnetic resonance imaging (MRI), it is essential to adhere to these guidelines to maintain safety for patients and the general public alike.

Inprior options reflecting higher magnetic field strengths, such as 3T or 5 gauss, may relate to operational or technical specifications in MRI contexts but are not applicable as public exposure limits. Therefore, adhering to the 400mT threshold is crucial for ensuring safety standards in public health regarding magnetic field exposure.
