For most people nowadays, their smartphone is within arm's reach 24 hours a day. It's in their pocket while they're at work, it's in their hand on the train ride home and it's on their bedside table as they go to sleep. With this level of proximity and usage, many can't quite shake the niggling feeling that they might be risking damage to themselves in the long run. While conclusive longitudinal research on the effects of cell phone radiation is still hard to come by, for those looking to hedge their bets, this infographic shows the phones that emit the most radiation when held to the ear while calling.
The German Federal Office for Radiation Protection (Bundesamt fur Strahlenschutz) has a comprehensive database of smart phones - new and old - and the level of radiation they emit. Following the criteria set for this chart (see footnotes), the current smart phone creating the highest level of radiation is the Mi A1 from Chinese vendor Xiaomi.
