For the third year running, with a SAR of 0.17, the Samsung Galaxy Note 8 with dual sim is the lowest radiation smartphone available today in the U.S.

The Samsung Galaxy Note 8 has dual cameras – 12MP rear camera’s with OIS and 8MP front Camera with auto focus – offering great selfies and great quality photos. There’s also a 6.3-inch edge-to-edge screen and a built in S Pen.

For storage, expect 64 GB of internal memory with a removable Micro SD slot to expand storage up to 256GB. You also get 6GB RAM and, my favorite feature, this one is water and dust-resistant! (Though I haven’t tested it for resistance to toddlers or sand).

Why we like Samsung

Samsung is one of the most sustainable companies currently offering smartphones for use in the U.S. It has taken steps towards implementing a circular materials economy, boasting a decent takeback recycling program. The company also tends toward using eco-friendly packaging that can be upcycled, including turning TV box packaging into a cat house or end table.

That said, Samsung has also invested in cluster munitions, so it’s not all sunshine and roses at the company.

With a relatively low SAR value of 0.352 and one of the best battery lives around (12 hrs, 46 mins), the LG V60 ThinQ 5G is a great choice for an energy efficient, low radiation smartphone.

Why we like LG

LG Electronics is a South Korean company that boasts some credible eco-friendly initiatives. It’s one of our top picks for eco-friendly TVs, making award-winning TVs that are easier to recycle, for instance. LG introduced its Eco-Index in 2011 as an internal environmental assessment standard for product sustainability. The company’s goal is to increase the proportion of more sustainable and energy-efficient Green 3 Star products in its range, as detailed in LG’s sustainability report (2020-2021).

LG is also shooting for a 50% reduction in carbon emissions in the production stage by 2030 over 2017 levels. The company is also aiming for complete carbon neutrality and already claims to use 80% renewable energy in its American business operations.

As for toxicology, LG Electronics complies with international regulations on hazardous substances including RoHS and REACH, and has a supply chain green management program, the Green Program Plus, to monitor hazardous substances. The company is also phasing out phthalates, antimony trioxide and beryllium in products and is working on removing PVC and BFRs too.

Makes and Models of the Best Low Radiation Phones

The SAR (Specific Absorption Rate) is a measure of the amount of radio frequency energy absorbed by your body when you use the handset. There is wide variation between SAR scores for smartphones, and one of the best resources for finding out a SAR score for a phone you don’t have in your physical possession is the BfS listings.

Once again, for 2023, the BfS rankings show that the lowest SAR scores are associated with a range of satellite phones and smartphones only available in Europe. There are, however, quite a few Samsung phones too, along with a few LG, Motorola, Sony Mobile, Nokia, and even Google phones, all of which can be bought and used in North America.

Looking specifically at radiation measured when the phone is held to the ear (rather than the body), the following phones emit the least radiation and were available in North America at the time of writing (November 2022):

Sadly, many of the smartphones that emit the least radiation are only available in Europe or Asia, with some of the best Samsung models now discontinued in North America. Note, too, that Fairphone doesn’t currently work in North America, even if you do find one to buy here. Similarly, several of the models above only work with certain networks in the U.S. Several of the phones above are a great choice unless you want them to work with Verizon/Sprint, for example.

The Apple iPhones with the lowest radiation (SAR) score

Why should I care about my smartphone and radiation?

All cellphones emit radiation. How much varies by model and how you use the phone. Radiation from cellphones is not proven to cause cancer or any disease, but lack of proof isn’t lack of health impact.

If you’re looking for a primer on the health impact of cellphones, a good starting place for research is the CDC’s webpage on cellphone radiation FAQ. The FDA also maintains information on cellphones and health which you may find useful.

We’ll leave the health impact to the scientists. Instead, we’ll assume you’re here because you’re concerned about smartphone radiation and want to know how to tell how much radiation your phone emits and if there’s a low radiation phone that might be a better option for you.

SAR – How to Determine Cellphone Radiation

The SAR, or Specific Absorption Rate, is a measure of the amount of radio frequency energy absorbed by your body when you use the handset. Phones vary widely for SARs, but it’s very simple to find out the SAR for any given phone. That includes the smartphone you’re probably using to read this article!

To find the SAR for your iPhone or most other smartphones:

1. Open up your dial pad as though you’re about to make a call
2. Type in *#07# and click call
3. This will redirect you to a part of the settings on your phone
4. Click on RF Exposure
5. Scroll down to the link to a webpage with information for your device

You can also access this information on other phones using the same code. Some just pop up the SAR right away while others might take you to the settings on your phone. You can also find this on your iPhone through Settings, General, Legal and Regulator, RF Exposure, where you’ll find that link to the same webpage.

I was pretty shocked to see that my iPhone 7S has an RF exposure of 1.19, nearly ten times higher than the lowest emitters! And older iPhone models were tested at a greater distance from the head than newer models held to higher standards!

Samsung phones are usually low radiation

Although there’s great variation among cellphones, one thing is consistent: Samsung phones tend to have exceptionally low SARs. This is probably because in 2006 Samsung released a range of phones with a new style of antenna. Prior to 2003, the FCC in the US had a rule mandating omnidirectional antennas, i.e. those that transmitted in all directions. After 2003, Samsung (and other companies) were free to do things differently, which is why Samsung’s newer antenna radiates most of the RF away from the handset user.

That said, a 2019 investigation by the Chicago Tribune found that both the iPhone 7 and several Samsung models far exceeded the FCC’s regulations for SAR, prompting retesting by the FCC itself as well as by Samsung. In short, it’s no simple matter trying to figure out which phones have the lowest radiation.

One way to find at least some reassurance is to check the German Federal Office for Radiation Protection (Bundesamt für Strahlenschutz, BfS) which maintains a comprehensive database of smartphones and the amount of radiation they emit when held to the ear during a call. You might also want to check for the German certification for environmental friendliness ‘Der Blaue Engel’ (Blue Angel), which only certifies phones with a SAR below 0.60 watts per kilogram (far lower than the FCC’s 1.6 W/kg).

How to Minimize Radiation from Cellphones

Again, the CDC has a great webpage on this topic. The CDC clearly states, that while more research is needed, there is no scientific evidence conclusively linking cellphone radiation to diseases such as cancer.

However, if you’re concerned about radiation exposure, there are a few ways to reduce your exposure to radiation from your phone.

These include:

• Texting instead of calling
• Using your phone’s speaker function
• Wearing a phone headset or earpiece
• Using a landline!
• Using Pong’s cellphone cases that refocus RF energy away from your head without reducing signal strength.

In addition to the steps above, you can also intentionally make your next smartphone one with a low specific absorption rate (SAR) rating,

The bottom line

While the scientific evidence is unclear, some of us may want to limit exposure to radiation from all sources. Using a cellphone with a lower SAR score is one strategy for less radiation exposure in our everyday lives. If this is a topic you’re interested in and want to dig further, also be sure to have a look at our review of the safest microwaves.

It’s worth remembering, though that most smartphones only last two to three years, after which they’re usually traded in (hopefully) or shoved in that miscellany drawer of electronics (come on, we all have one!). Some companies are trying to do better, with more sustainably built smartphones coming to market that have a longer life, are designed with circular economy principles in mind, and that emit less radiation than earlier models.

If you’re less concerned about the radiation emitted by your smartphone and more concerned about overall sustainability, we’ve also got you covered for the best energy efficient and most sustainable smartphones.
