About RF exposure and Specific Absorption Rates (SAR) RF exposure and Specific Absorption Rates (SAR) SAR data information is provided for residents in countries that have adopted the SAR limits recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) or the Institute of Electrical and Electronics Engineers (IEEE). The ICNIRP specifies a SAR limit of 2 W/kg averaged over ten (10) grams of body tissue while the IEEE specifies a SAR limit of 1.6 W/kg averaged over one (1) gram of body tissue. These requirements are based on scientific guidelines that include safety margins designed to ensure the safety of all persons, regardless of age and health. The SAR values and test distances differ depending on the measuring method, the device tested (phone or tablet) and if the Wi-Fi hotspot functionality is used, but only the highest SAR values are presented. The WHO (World Health Organization) has stated that current scientific information does not indicate the need for special precautions regarding the use of tablets and phones.
