These phones release the most and the least radiation

These phones release the most and the least radiation
Every now and then consumers are whipped into a frenzy over the possibility that smartphone radiation leaks pose a health threat. A report released by The German Federal Office for Radiation Protection (Bundesamt für Strahlenschutz) reveals the amount of radiation emitted by some newer and older smartphone models. The data is released in watts per kilogram with the "safer" phones reporting lower scores.

The handset that emits the highest level of radiation, according to this data, is the Xiaomi Mi A1 (see image at the top of this article), which releases 1.75 watts of radiation per kilogram. The OnePlus 5T is second with a 1.68 watts per kilogram score. Some popular phones that you might find in the hands of U.S. consumers include the OnePlus 6T (4th place, 1.55 watts per kilogram), Pixel 3 XL (7th place, 1.39 watts per kilogram), Pixel 3 (12th place, 1.33 watts per kilogram) and the Apple iPhone 8 (14th place, 1.32 watts per kilogram).

Keep in mind that there is no specific number that would make a phone dangerous to use. German environmental group 'Der Blaue Engel' (Blue Angel) certifies smartphones with a watt per kilogram reading of .60 and lower, which means that all of the aforementioned handsets release more than twice the radiation that the organization is okay with.

What about those handsets that release low amounts of radiation? The Samsung Galaxy Note 8 and the ZTE Axon Elite are tied at the top, both releasing .17 watts per kilogram. The LG G7 ThinQ is tied with the Samsung Galaxy A8 for third (.24 watts per kilogram). Speaking of Samsung, half of the phones on this list are manufactured by the company. That includes devices like the Galaxy S8+ (.26), Galaxy S9+ (.29) and the Samsung Galaxy S8 (.32).

Oh no... here goes another one of those weird "science" claims that the public believes, just like how microwave ovens give you cancer if you stand too close. The "radiation" used by cell phones falls under microwaves in the electromagnetic radiation spectrum. These waves are not nearly powerful enough to pose any health risk. As for microwave ovens, you won't get cancer standing next to them. Hell, you won't even get cancer standing IN one, you'll just heat up like crazy. Microwaves don't break molecules apart, they simply cause them to spin Don't skip science class, kiddos.

kind of glad radiation emits alot on iphones, less sheeps in the next generation.

It's okay that iPhones have some of the highest radiations. After all their users frequently get 'brainwashed' by Apple which should clean out some of the radiations.

Wait... Didn't we see a similar article a few weeks ago from a different source that had iPhones mostly in the top 10 of highest radiation levels?

Wow what a surprise, Chinese phones have the worst scores..

I am assuming the higher the amount the stronger the signal and reception for cell signal and wifi signal/reception

Not really, check out signal strength test and 4G speedtest around the internet. Galaxy S and Note line always one of the best.. But look at their radiation level.

Wow, I'm surprised LG made it so high on the good list. I wonder if the V35/40 emits similar amount to the G7 considering they're practically identical internally..

True not a single LG, Motorola, Nokia, Samsung or Blackberry says alot.

I don't know where did they take all this data from, but from a quick search around the internet, i can see very different numbers as compared to the table above. Moreover, there is an inherent flaw in how SAR value has been reported in here. SAR value is measured for both head and body. While they have ranked devices based just on Head SAR values while omitting Body. For example Note 8 has 0.34 watt/kg at head and 1.01 watt/kg at body(for some regions). While in other regions same Note 8 has 0.173 watt/kg for head and 1.3 watt/kg for Body. Similarly OnePlus 5T has 1.4 watt/kg for head and 0.51 watt/kg for body in India, US and Canada. Much lesser than this report. From what i have seen SAR values are higher in European region. And there is no hard and fast rule. If SAR value is high for head, it will be low for body Or Vice Versa. It all depends on where the main antennas are placed inside the phone, top or bottom.

Some would argue that sensitive brain tissue is a more important factor when measuring RF, thus weighing head measurements more heavily. The above results are head measurements and variations in results among countries/testing organizations mostly results from different measurement standards (reception signal strength, temperature, distance etc). Lastly, a high value for the head does automatically mean a low value for body or vice versa. There are phones where this is the case, but there are also phones where both are low (Note 3) or both high (iPhone 8 for example).

How do you have a higher watt/kg at body than head? The phone is emitting a more or less constant level, and the body has more mass than just the head.

I'd guess the head absorbs radiation differently than the body. How you hold the phone(angle) against the head can also affect the absorption rate.

2g/3g/4g antennas are located inside a device either at top or at bottom. So when one is on a call, if a phone has antennas at top, it's radiation at head will be higher while considerably lower for rest of the body down. But if a phone has antennas at the bottom, it's radiation will be higher towards body and lesser towards head.

Wow Samsung, Cudos! That’s extraordinary compared to iPhone which I’m a fan of.

Right, they should use this in their marketing.

The limit for devices in US/Canada is 1.6. I'm not sure how the Oneplus 5T passed or else the testing methods differ. Or maybe I'm reading into this articles info wrong...

Different test = different result.. And the limit in German (or EU) is 2.0. So it's still okay.

1. When it comes to a pass/fail for whether a device can be sold in any jurisdiction I'm sure the manufacturers don't have a - oh well, different test = different result attitude. 2. I'm well aware that the allowed limit is higher in Europe. Whether or not it is, as you say "still okay"...Well... For me, I'm with Vokilam in post #2 - cudos to Samsung!
