Negative waves: some smartphones still have too high a SAR

The SAR or specific absorption rate indicates the radiation or radiation emitted by a mobile. Expressed in watt per kilo (W / kg), this value must not exceed 2 W / kg otherwise the phone in question would become dangerous for its user. Following a tightening of the regulations, no less than 16 smartphones have been singled out by the National Frequency Agency (ANFR).

16 phones pinned between 2016 and 2019

Compliant with the legislation a few years ago, smartphones are today pinned by the ANFR. Before 2016, manufacturers could determine the distance between the phone and the user’s body. This could then reach 25 mm. To really get closer to the real conditions of use, the measurements are, since 2016, carried out at a distance of 5 mm.

After the implementation of this new regulation, the National Frequency Agency (ANFR) “Detected 16 phones that did not comply with the new regulations” between 2017 and 2019. While some smartphones have been updated since, thereby reducing their SAR, others have simply been recalled, such as the Neffos X1.

Tests had already been carried out between 2012 and 2016 “On nearly 300 telephones positioned close to the trunk, in contact and at a distance of 5 mm”, indicates ANSES. “The results revealed that a large proportion of the phones tested had SAR values ​​greater than 2 W / kg, some exceeding 7 W / kg on contact”, adds the Agency in its report.

To reduce exposure, ANSES asks manufacturers to deploy software updates on their smartphones and, if this is not possible, to organize a recall of the models concerned. Waiting, “The Agency invites the users of these telephones, when worn close to the body, to comply with the terms of use, in particular the distance distances mentioned in the instructions for the telephones”.
