Your wallet, your keys and – your mobile phone, of course! If you’re like most people, you never leave home without this trusty trio. But our attachment to our phones has sparked concerns that exposure to the radiation they emit is a health risk.
To prevent excessive heating of body tissue, manufacturers are required to ensure that their mobile phones meet strict RF emission limits. Given as a unit called the specific absorption rate , which is a measure of the amount of RF energy absorbed by the body when using a mobile phone, the limit in the European Union is 2 watts per kilogramme.
A data bank can be accessed courtesy of the BfS that shows phones’ SAR. The Xiaomi Poco F2 Pro has a SAR of 0.79 W/kg, for instance, and the iPhone 12 a SAR of 0.98 W/kg. Even the Samsung E1080, which came out in 2009, has a SAR far below the limit: 0.64 W/kg
