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.

Many thanks to S21 & the participants for sharing this useful
Following suggestions as preventive measures
might help to minimize the harmful effects :-
1- All Mobile
Phones to prominently display SAR Absorption Ratio and the recommended
2- Mobile Phones to be used as a necessity
>> not as luxury.
Awareness of its harmful effects be made
compulsory in form of printed leaflets in the languages of that
3- More awareness to minimize the duration of
use at one time.
4- The Cell Phones be kept as far as
possible away from the ear.
5- Cell phones be kept as far
away from human body as possible >> specially when not in use
and during sleep.
6- Special Mobile cases be introduced
which can prevent/absorb its Electro-Magnetic Radiations from
dissipating; when not in use.
7- Special precautions for
limits of use in Kids, growing females/males; pregnant women.
8- Serious considerations for restrictions of use in
Technology be used & not misused / over-used without
Wishing everyone good

Thank you for the useful information on SAR values on your website.
You write that phones with high SAR values may operate at much
lower levels and phones with low SAR levels may operate at higher
rates. While I would not rely on a low SAR level as being safe, can I
assume that a phone with a low level is generally safer than one with
a high level?
How can I find out at what level the phone is
Are you saying that a phone with a low SAR
might constantly operate at the maximum (low) level quoted, while
phones with a high maximum level might actually operate at a very low
level most of the time so that In practice I might be better off
buying a phone with a higher SAR level? How would I find out?

The SAR values quoted by manufacturers are maximum operating values.
The actual value in use will depend on network strength and other
factors. Generally speaking, on average a phone with low SAR rating
will emit less radiation than one with a high rating. If you are
concerned about radiation, it would be advisable to choose a phone
with a low SAR rating, but just as important is choosing a network
that gives consistently good reception and using your phone in
locations with the best network strength - perhaps close to a

Great info on your site thank you. I only wish the details about
phones gave the SAR rating. Carphone Warehouse used to give them in
their brochures. I too find that using one for half a minute or so
with a SAR over 0.4 gives me a sore head on that side which can last
quite some time. And of course in a car it is much worse - even if my
husband next to me is using his Vodafone I am aware of the discomfort.
I tell all my friends and family to use SAMSUNG as they tend to be the
lowest. Can't think why Samsung don't publicise this fact!

The values for the Nokia N95 are for the RM-159 which was the original version released in the UK. Other markets may have different versions and the SAR values may be different.

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!!

I phones are particulary high in sar

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
