3.2.3 INTERNATIONAL COMMISSION ON NONIONIZING RADIATION PROTECTION
The ICNIRP’s mission is to coordinate knowledge of protection against various
nonionizing exposures in the development of internationally accepted recommendations. The ICNIRP guidelines [12–14] specify “basic restrictions” and “reference
levels.” Basic restrictions on exposure to magnetic fields are based on established
adverse health effects. For magnetic fields below 100 kHz, the physical quantity used
to specify the basic restrictions is current density induced inside the body. Reference levels are values that are provided for practical exposure assessment purposes
to determine whether the basic restrictions are likely to be exceeded. Compliance
with the reference levels is designed to ensure compliance with the relevant basic
restriction [14].
