Researchers in Switzerland have found that a mobile-phone communications protocol exposes users to about 100 times less low-frequency electromagnetic fields than its predecessor. The result builds on previous research to show that UMTS offers less overall exposure to electromagnetic fields than GSM (Phys. Med. Biol. 588339).
Characterizing the emission of electromagnetic fields from mobile phones is seen to be an important area of research because of widespread concern that wireless devices can affect human health. Strong radio signals are known to heat tissue, while strong low-frequency fields – generated, for instance, by supply currents or audio speakers – are known to provoke neurones in the brain into firing spontaneously. For these reasons, governments issue strict safety guidelines about the maximum exposure that users should receive. […]
