The Samsung Galaxy S8 Plus has a EU Head SAR of 0.27 W/kg which is 13.50% of the EU legal limit of 2.00 W/kg!

Phone radiation limits are different depending on where you live. The FCC/IC (USA Standard) and the Council of the European Union (EU Standard) are measured over a different amount of tissue, either 1g or 10 grams, and different maximum power levels of 1.6 W/kg vs. 2.0 W/kg, so they are not directly comparable.

• The SAR limit set by the FCC/IC is 1.6W/kg, averaged over 1 gram of actual tissue.
• The SAR limit recommended by the Council of the European Union is 2.0W/kg averaging over 10 g of actual tissue. Click these links to display EU ratings for   EU Head and EU Body
