There exist a number of national and international regulations, standards and recommendations dealing with exposure to radio frequency electromagnetic fields. The limits are generally very similar and usually based on recommendations from the World Health Organization (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

The limits take into account a wide margin of safety in order to protect people from all known effects on health of both short-term and long-term exposure to electromagnetic fields. The standard measure of absorption of radio frequency fields is called the Specific Absorption Rate, or SAR.
