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.

Axar.az reports citing Statista that, 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 Mi A1 from Chinese vendor Xiaomi. Another Chinese phone is in second place - the OnePlus 5T. In fact, the two companies are represented heavily in this list, with 8 of the top 16 handsets being made by one of them. Premium Apple phones such as the iPhone 7 and the recently released iPhone 8 are also here to be seen, though, as are the latest Pixel handsets from Google.

Having already revealed the current phones which emit the most radiation, this chart looks at the opposite end of the scale. While conclusive longitudinal research on the effects of cell phone radiation is still hard to come by, for those looking to minimize the risks, this list may be useful.

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 when held to the ear during a call. Following the criteria set for this chart (see footnotes), the smartphone creating the lowest level of radiation is the Samsung Galaxy Note8 - with a specific absorption rate of 0.17 watts per kilogram. In fact, Samsung handsets feature prominently, with half of the top ten coming from the South Korean company. This contrasts starkly with their major rival Apple. Two iPhones occupy a place in the list of phones which emit the most radiation, compared to none from Samsung.
