Working closely with health and safety organizations, the FCC and other spectrum authorities around the world have adopted limits for exposure to radio frequency (RF) energy. For devices used closer than 20 cm to the head or body, the RF exposure limits are given in terms of the Specific Absorption Rate (SAR), which is a measure of radio frequency energy absorbed by the head or body. As part of the equipment authorization process, manufacturers are required to ensure that their devices comply with these limits for exposure. The FCC and Industry Canada limit for public exposure is a SAR level of 1.6 watts per kilogram (1.6 W/kg). The European Union and many other countries have a SAR limit of 2.0 W/kg.
