Report: Smartphones Emitted the Most and the Least Radiation

One of hottest topic in Google Trends today is smartphone radiation. The report released by Bundesamt für Strahlenschutz, which is The German Federal Office for Radiation Protection, has disclosed the amount of radiation emitted by headline smartphones nowadays. As the topic brought up so many controversies, we just cannot omit it.

What is the most important feature when choosing smartphone?

At present time, people are tend to choose any item based on how it looks and how trendy it is. And smartphones are no different. The best features for most users are amazing camera and enough memory. Some websites give the guide how to choose better smartphones, where they rank the following features:

  1. Design and build quality
  2. Screen
  3. Great camera
  4. Headphone jack
  5. Battery life
  6. Processor power
  7. Price

As you can see no one tells you whether it will be safe to use it or not. Indeed, people are aware that smartphones as any other electronic devices emit radiation, yet, they do not pay much attention to it, though they should do.

Radiation effect on body

According to the United States Environmental Protection Agency, radiation has energy to affect the atoms in living cells and thereby damage their genetic material (DNA). The cells in the body are able to repair the damage, however, if the damage is not repaired correctly, a cell may die or eventually become cancerous.

Exposure to low levels of radiation (like smartphones other electronic devices) encountered in the environment does not cause immediate health effects, but is a minor contributor to our overall cancer risk.

The phones emitted the most radiation

The data is calculated in “watts per kilogram”, and lower scores mean lower radiation emission from the smartphone. The report shows that Xiaomi Mi A1, OnePlus 5T, and Xiaomi Mi Max 3 are the leaders of the rating, meaning that they emit the most radiation.


The fourth place is taken by OnePlus 6T, which did not go far away from its forerunner in terms of radiation, 1.55 and 1.58 correspondingly. HTC U12 life shuts down the top 5 with the result of 1.48 watts per kilogram.

Google Pixel 3 XL (1.39) did not fare much better, as well as his brother Google Pixel 3 (1.33). The owners of iPhone 7 and 8 should also start worrying about their health, as the results show 1.38 and 1.32 correspondingly. The newcomers like the iPhone XR (0.99), iPhone XS (0.99), iPhone XS Max (0.99) and the iPhone X (0.92) fare much better.

The phones emitted the least radiation

Samsung smartphones are doing best in the radiation chart. Eight phones released by this company emerged in the chart of the phones emitted the least radiation. The first in the rating is Samsung Galaxy Note8 unveiled on August 23, 2017.


The LG G7 ThinQ (0.24 watts per kilogram of radiation), the HTC U11 Life (0.28) and the Motorola Moto Z (0.30) have also done well in terms of limiting radiation emissions during device usage.

The Huawei Mate 20 Pro hits the charts with 0.4 watts per kilogram. At the same time, the Honor 8 Pro registers 1.28 watts per kilogram of radiation.

It should be noticed that the German Federal Office for Radiation Protection did not test Chinese phone companies Oppo and Vivo.

It is also important to note that the German environmental agency Blue Angel certifies smartphones with a watt per kilogram reading of 0.60 and lower.
