Popular smartphones should radiate greatly

A US newspaper has been researching popular smartphones on your radiation values. For iPhone and Galaxy models, the boundary values ​​were significantly exceeded. Now, the FCC is investigating.

The Chicago Tribune has investigated several smartphones from major manufacturers such as Apple's iPhones, Samsung Galaxy devices or Moto models by Motorola in terms of your radiation. The most surprising result of these tests: Popular smartphones such as the iPhone 7 or the Galaxy S9 significantly exceed the US limit value. Even according to manufacturer-criticized tests, the radiation was higher than allowed. Now the US-FCC once again has to know who Phone-Arena writes.

Exceeded SAR value of tested smartphones

How dangerous the radiation emitted by humans to smartphones is has not been conclusively clarified. It is clear that the tissue is warmed by high radiation, the danger of increased consequences. As the value for the absorption of electromagnetic fields in a material that leads to this warming, the SAR value (specific absorption rate) is retrieved. In the United States, the limit applies at a SAR value of 1.6 watts per kilogram. According to the WHO recommendation, the upper limit value lies at two watts per kilogram. This limit also applies in the EU.

The Apple iPhone 7 and the Samsung Galaxy S8 are in the tests of the Chicago Tribune with 7.15, respectively, 8.22 watts per kilogram of a variety over the limit values. Newer devices, such as the iPhone 8 (5.37 watts per kilogram) or the Galaxy S9 (3.8 watts per kilogram), clearly exceed those limits. The US newspaper had already measured the radiation from a two millimeter removal. Normally, the SAR value is determined from a removal of five millimeters from the body – also in the EU, as the Futurezone reports.

Modified tests also show higher beam values ​​as allowed

The Chicago Tribune argues that users currently carry the smartphones directly in the body, whether in the shirt or pants pocket, and not more in a belt or handbag than in the past. Apple disputed the newspaper's findings, explaining that the test sensors would have had to be switched on, which would drain that performance when the phones were held face to face or ear phones. However, even with these modified tests, the smartphones have still exceeded the SAR limit values ​​of the authorities. Here, the FCC wants to take the devices concerned even more precisely under the magnifying glass.
