Federal Communications Commission(FCC) has set certain threshold value on amount of SAR value. If your mobile phones exceeds that value, then it is not good for your health. It releases radiation that will have bad impact on tissue cells.

What is the Threshold SAR Value set by FCC:

It varies from region to region. European Union including UK adopts the threshold SAR values as 2.0 W/Kg for 10 grams of body tissue whereas USA and remaining countries set SAR threshold value as 1.6 W/Kg for 1 gram tissue.

EU and UK – 2.0 W/Kg

USA and Rest of the Countries – 1.6 W/Kg

All the mobile phone manufacturers in these regions should comply with these limitations on amount of radiation it emits.

Here is the list of all mobile phones and its corresponding SAR value:
