What Is Specific Absorption Rate (SAR)?
SAR is the unit of measurement used in radio-wave exposure guidelines. Tests for SAR are conducted using standardised methods, with the phone transmitting at its highest certified power-level, in all employed frequency bands. While SAR levels may vary between LG phones, they are all designed to meet the relevant guidelines for exposure to radio waves. The SAR limit recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) is an average of 2 W/kg over 10 grams of tissue. The SAR limit recommended in countries governed by the Institute of Electrical and Electronics Engineers (IEEE) is an average of 1.6 W/kg over 1 gram of tissue.
