Three smartphone manufacturers have changed the transmission power of their devices to limit the exposure of users to electromagnetic waves, after a formal notice from the National Frequency Agency (ANFR), it announced on Monday July 11. “The companies Samsung, Hisense and Gigaset have taken the decision to reduce the power of their terminals via a software update”ANFR said in a statement.
The agency responsible for controlling the use of the electromagnetic spectrum, used in particular for wireless telecommunications, had checked the Galaxy Note 10 Plus (Samsung), Infinity H30 (Hisense) and GS290 (Gigaset) phones and identified values exceeding the limits imposed by European regulations.
Exposure to weak waves: an unproven dangerousness
These frame the specific absorption rates (SAR), a concept that quantifies the energy transported by electromagnetic waves and absorbed by the human body. Measurements are taken in several typical situations, phone in hand, close to the body or the head. The update applied by the manufacturers “makes localized SARs compliant with regulatory limits of 4 W/kg (watts per kilogram) and 2 W/kg. »
Samsung Galaxy Note 10 Plus and Hisense Infinity H30 devices thus drop from 4.3 W/kg before their update for localized measurement “member” at 2 W/kg, while the Gigaset GX290 sees its SAR localized ” trunk “ decrease from 2.9 to 0.8 W/kg.
According to the World Health Organization (WHO), “There is currently no indication that exposure to low-intensity electromagnetic fields is dangerous to human health” And this “despite much research”.
