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 für Strahlenschutz) has a comprehensive database of smartphones - new and old - and the level of radiation they emit. Following the criteria set for this chart (see footnotes), the current smartphone creating the highest level of radiation is the 5T from Chinese vendor OnePlus.
In fact, the top list is dominated by handsets made by Chinese companies, with OnePlus, Huawei and ZTE accounting for 9 of the 15 phones with the largest values. It must be said though, that premium Apple phones such as the iPhone 7 and the recently released iPhone 8 are also here to be seen.
While there is no universal guideline for a ‘safe’ level of phone radiation, the German certification for environmental friendliness ‘Der Blaue Engel’ (Blue Angel) only certifies phones which have a specific absorption rate of less than 0.60 watts per kilogram. All of the phones featured here come in at more than double this benchmark.
