What is SAR (Specific Absorption Rate)?

Do you have a description of SAR (Specific Absorption Rate)?

Electronic devices emit non-ionizing radiation which can be measured to determine a Specific Absorption Rate (SAR). SAR shows the amount of radio frequency (RF) energy that is absorbed by your body. Each smartphone has a specified SAR value. Information about its level can be found in a device user manual, in the mobile phone’s settings or in the online SAR database.

While talking on the phone, we are exposed to NIR radiation. It is generated by the transmission of signals between the mobile phone and the mobile base station. Your phone needs to use high-frequency electromagnetic fields to transmit voice and data. While talking on a mobile phone, some of the energy from these fields penetrates the head.

Specific Absorption Rate (SAR) shows how much radiation was emitted by the phone and absorbed by the tissues; it shows the degree of warming that occurred. SAR refers to the amount of radio frequency energy absorbed by the human body when using a mobile phone. It is the speed with which the radiation emitted by the smartphone is absorbed by the body. The lower the SAR value, the better.
