Smartphones do emit radiation.
According to research conducted the German Federal Office for Radiation Protection (Bundesamt für Strahlenschutz), Xiaomi Mi A1 emits the highest level of radiation in a list of current smartphone models, followed by the OnePlus 5T.
The list of top 16 smartphones emitting the most radiation, compiled by Statista — based on the data provided by the German body, consisted mainly of models by Xiaomi and OnePlus. On the other hand, Samsung phones are generally found to emit the least radiation. Particularly, the Samsung Galaxy Note 8 and ZTE Axon Elite have emerged as the lowest radiation-emitting phones with a specific absorption rate (SAR) of 0.17 watts per kilogram.
The Xiaomi Mi A1 emits the most radiation with a specific absorption rate of 1.74 watts per kilogram, while the OnePlus 5T, which comes second, has an absorption rate of 1.68 watts per kilogram. The Mi Max 3 sits at the third position with the specific absorption rate of 1.58 watts per kilogram. The OnePlus 6T, which is OnePlus’ latest flagship, is also among the five phones emitting the highest level of radiation with an absorption rate of 1.55 watts per kilogram.
Xiaomi and OnePlus featured heavily in the list of phones emitting the most radiation (eight of the top 16 smartphones). Don’t forget, Apple’s iPhone 7 is also on the list with an absorption rate of 1.38 watts per kilogram, just shy of OnePlus 5’s 1.39.
Other premium models, like the Google Pixel 3 XL , Pixel 3, and the Apple iPhone 8 are all part of the high emitters list. No Samsung models are in that list though.
Meanwhile, the list of phones emitting the least radiation compiled by Statista highlight a list of Samsung models, including the Galaxy Note 8, Galaxy A8 (2018), Galaxy S8+, Galaxy S7 Edge, and Galaxy S9+.
So, what do these SAR numbers mean? Unfortunately, there is still no universal guideline that sets a “safe” level for cellphone radiation. As Martin Armstrong of Statista notes in a post, there isn’t any universal guideline for a safe level of phone radiation. However, the German certification for environmental friendliness called ‘Der Blaue Engel’ (Blue Angel) only certifies models that come with a specific absorption rate of fewer than 0.60 watts per kilogram.
Nevertheless, do practise moderation when it comes to smartphone usage. Your eyes too will thank you.
