Galaxy SAR Value

What is SAR? SAR stands for Specific Absorption Rate which is the unit of measurement for the amount of RF energy absorbed by the body when using a mobile phone. Although the SAR is determined at the highest certified power level in laboratory conditions, the actual SAR level of the phone while operating can be well below this value. This is because the phone is designed to use the minimum power required to reach the network. Therefore, the closer you are to a base station, the more likely it is that the actual SAR level will be lower.
The Samsung Galaxy Note 9, Model SM-N960U ranks well among popular Smartphones as the lowest SAR Smartphone in 2018 with a Head SAR Level of only 0.33 W/kg (watts per kilogram averaged over one gram of tissue) at 5 MM from the head. However, there is a lot more to phone radiation safety than SAR levels alone!
