SAR (specific absorption rate) is a measurement of how much electromagnetic radiation is absorbed by body tissue whilst using a mobile phone. The higher the SAR the more radiation is absorbed.
In Europe, the European Union Council has adopted the recommendations made by the International Commission on Non-Ionising Radiation Protection (ICNIRP Guidelines 1998). These recommendations set a SAR limit of 2.0 W/kg in 10g of tissue. The UK Government has endorsed this limit (following a report by the Independent Expert Group on Mobile Phones) and the five mobile phone network operators have agreed to voluntarily adopt the ICNIRP guidelines for public exposure. All mobile phones on sale in the UK comply with this limit.
In the United States, the Cellular Telecommunications and Internet Association (CTIA) requires all cell phones to comply with the Federal Communications Commission (FCC) SAR limit of 1.6 W/kg in 1g of tissue.
How to reduce your exposure to phone radiation
- Do not use your phone more than necessary and keep your calls short
- Send a text instead of making a call
- Try to avoid using your phone if the signal strength is low - find a better location to make a call
- Try to use the phone outdoors rather than inside, or move close to a window to make a call
- Keep the phone (and particularly the aerial) as far as possible from your head
- Avoid touching the aerial while the phone is turned on, and keep the phone away from areas of the body such as eyes, testicles, breasts and internal organs
- Limit usage as much as possible if pregnant
- Switch off your phone when not in use
You should be aware that if the phone is receiving a very strong signal from a base station, then power output can be reduced by up to 1000 times compared with when the phone has a poor signal.
As SAR information is not always easy to find, we have compiled a list of SAR values for most phones available in the UK. Please note that S21 accepts no responsibility for the accuracy of this data. All data has been collected from third party sources and in each case the source of the data is referenced. You are advised to verify the accuracy of this information for yourself. Under no circumstances will S21 be held liable for any loss, injury or damage associated with the use of this data.
You should note that while the SAR values of individual phones may vary, every phone available for sale in the UK complies with ICNIRP guidelines. You should also be aware that the SAR values shown are maximum values and in practice emissions from mobile phones will normally be lower than these figures. The emissions depend on factors such as distance from a transmission mast, whether the phone is used indoors or outdoors, how close the phone is held to the ear and other operating factors. It is important to realise that a phone with a high SAR rating may actually operate with much lower emissions in practice, and conversely a phone with a lower SAR rating may operate with emissions higher than a high SAR phone in practice. You should not rely on a low SAR rating to guarantee your health.

Hello I would like to know the sar value of Jiayu g4 mobile phone
Comment by John Hart from UK on 12th Sep 2013
Is it possible to find the SA rates for digital landline cordless phones, please?
Reply by S21 from UK on 13th Sep 2013
We don't publish that info here. Generally speaking, we would expect the SAR
for cordless phones to be much less than mobiles, since they are transmitting
over a short distance (100m instead of several km).
Comment by Dee from UK on 15th Aug 2013
This is really useful. Thank you to those who put it all together. I just wonder
if it would be too much trouble for the website to also list these in order
of SAR value, so that not only can we see the SAR rating of our current phone,
but can also easily ascertain which phone to go for if we want to buy a new
one with the lowest SAR possible.
Reply by S21 from UK on 17th Aug 2013
Hi Dee, thanks for your comments. Most of the phones listed here are now old,
so we're not sure how useful this would be.
Comment by akif from türkiye on 24th Jul 2013
are these sar values for head or body ?
Reply by S21 from UK on 25th Jul 2013
They are maximum values.
Comment by Dave from UK on 27th Jun 2013
I'm still using an old Sony Ericsson Z600 which is 10 years old. It has a very
low SARS rating 0.16 and I can't find a modern phone with the same. If I use
anything with a higher rating than that, I get headaches and the side of my
face,teeth and jaw goes numb. People laugh at me, but I'm not making it up.
Like a previous post said, they are keeping quiet about it.Just because you
are not sensitive to it, doesn't mean its not there!!
Comment by JYOTHI from INDIA on 26th Jun 2013
WHAT IS THE THRESHOLD VALUE ABOVE WHICH THE :SAR" VALUE IS HARMFULL OR WHICH
RANGE IS SAFE...
Reply by S21 from UK on 26th Jun 2013
No value of SAR has been shown to be harmful. All phones comply with the legal
limits that are set by authorities, as detailed in the introduction to this
Comment by Jenny from USA on 16th May 2013
SARS rating is very important to me. Just want a phone with:1.low sars rating
2. great camera 3. easy contacts(call waiting, calls missed, caller id...) I
would like to be able to listen to UTube. What's my WOW phone?
Comment by sean from uk on 1st Apr 2013
you might be interested in this film.
very relevant to sar rating
Comment by ron taylor from uk on 24th Jan 2013
I think sar ratings are very important,but it seems to be ignored,the same as
warnings about cigarettes were in the early days.We are sure to see an increase
in brain tumors in the coming years
I phones are particulary high in sar
THE POWERS THAT BE SEEM TO PREFER TO SHOVE IT UNDER THE CARPET///monetary concerns???
Comment by Susie L from UK on 8th Oct 2012
Me again as a follow-up to your reply to me below. WHERE exactly is the SARS
ranking for the 4 and 4S Three i-phone. It does not appear to be in the list
above or if it is, what is listed under?
Reply by S21 from UK on 8th Oct 2012
Hi Susie, listed alphabetically under Apple.
Comment by Susie from UK on 28th Sep 2012
I have an i-phone 3S - my contract is due to expire soon. Am considering upgrading
to a 4 or 5S, (like I usually do). On your list above of SAR rankings, it appears
to only go up to 'S' alphabetically! So I am not really sure what my Three (3)
i-phone is! I have recently had cancer so although I realise having an i-phone
with a low SAR is no guarantee, I thought I might as well go for a low one -
it might just help me psychologically!
Reply by S21 from UK on 1st Oct 2012
Hi Susie, we've updated the table for the iPhone 4S and 5. They have relatively
high SAR values, but obviously still within legal limits.
Comment by Daniel from UK on 10th May 2012
Does anyone actually care?
The procedures of reducing SARs seems pedantic.
Turn of phone when not in use - devotes the punt of a mobile phone
Try too use the phone out doors - lol

Guys...Im 15 years old and I've bought samsung galaxy ace(0,625 sar).Isnt that
Reply by S21 from UK on 21st Apr 2012
Stelios, you can see from the figures above that 0.625 is lower than most phones
and well below the EU limit of 2.0.
