What is the ICNIRP limit reserved for general public exposure in mT?

The correct choice is based on the guidelines set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) regarding magnetic field exposure. For general public exposure, the ICNIRP limits are considerably lower than those set for occupational exposure due to the higher sensitivity of the general public, including vulnerable populations like children and patients with medical implants.

The limit for general public exposure to static magnetic fields is specifically set at 400mT (millitesla). This level takes into account safety precautions to ensure that non-occupational individuals are not subjected to health risks associated with exposure to strong magnetic fields. While the other options present higher thresholds, they exceed the safety recommendations that have been determined to minimize potential effects on human health in non-occupational settings.
