Cell phones are emitting EM-RFW (Electromagnetic radiofrequency waves) which is non-ionizing radiation. It can affect the human body in a lot of ways.
The different phone company has different radiation levels. To limit these radiation levels the World Health Organisation (WHO) and the Federal Communication Commission (FCC) laid down a specific limitation for human exposure to EM-RFW (Electromagnetic radiofrequency waves) by the cell phones which is known as SAR Value(Specific Absorption Rate).
At the end of this article, I have added some FAQs related to SAR value which will really helpful for you.

What is the Specific Absorption Rate
SAR value means Specific Absorption Rate. SAR is the rate of absorption of Electromagnetic Radiofrequency waves by the body tissue. It is measured at a specific area of a specific body part that absorbed the maximum EMRF waves and then averaged over a kilogram.
The exposure guideline by FCC states SAR value should be at or below 1.6 watts/Kg averaged over 1 gram of tissue and by WHO(World Health Organisation) Sar value should be at or below 2 watts/Kg averaged over 10 gram of tissue.
When cell phone emits Radiofrequency waves some waves are absorbed by our body. This is called SAR, Remember This value does not deal with how much radiation cell phones emit it only deals with our body. So, from a single SAR value, we can not judge that your phone is completely safe.

How to check the SAR value of your phone
There are many methods to check the Specific Absorption Rate of a mobile phone, but here I will tell you the best 2 methods to check the SAR value of your mobile phone.
1. Check the Specific Absorption Rate of mobile phone by USSD Code
This is the best and quick method to check the Specific Absorption Rate of your phone, To check value follow the instruction below.
- Open the dialer pad of your phone.
- Dial *#07#
- Press the call button and follow the instruction.
If this method does not work on your mobile phone then try another method below, if the problem persists then comment below with your model number, we will tell you SAR (Specific Absorption Rate) of your phone.
2. Check SAR value of your phone by manufacturer
Some common phone company mentions there products the Specific Absorption Rate in their Website, If you know your phone’s model name then you can check SAR value by clicking on the link.

Facts about Specific absorption rate of cell phones
Cell phone radiation has limitless health effects on the human body. Some peoples claim that there are no harmful effects of cell phone radiation because they emit non-ionizing radiation (Which is different from ionizing radiation). Actually, it is a myth because previously there was no research to support the fact that cell phone radiation is harmful but now there is some research clearly shows that mobile phone radiation is harmful.
There are facts like increasing numbers of cell phones, Continuously changing cell phone technology (3G to 4G then now 5G) and increasing the time that we are spending on a cell phone (We can’t say a cell phone actually, because people have multiple cell phones now) is actually increasing risk on health. Another fact is cell phones are not only harmful to health they also triggering behavioral problems.
SAR value is just a single measurement of a very small part of the radiation that cell phone emits. We can not take any decision on the basis of SAR value (I am not saying that we don’t have to check the Specific Absorption Rate I just want to show you the broadness of radiation).

FAQ’s Related to SAR Value
1. What level of SAR is safe?
According to FCC(Federal Communication Commission), SAR should be at or below 1.6watts/kg averaged over 1gram of tissue. According to WHO(World Health Organisation), SAR should be at or below 2watts/kg averaged over 10gram of tissue.
2. What is the best SAR value?
Normal SAR is 1.6watts/kg(In 1g tissue), but below 0.4watts/kg is best SAR value.
3. How can reduce SAR?
SAR is the rate of absorption of Electromagnetic Radiofrequency waves by the body tissue. The rate of absorption is reduced when you kept your phone away from your body. You can do it by………
- Using Earphones/Headphones
- Use speakerphone in a long talk
- Limit the use of phone
- Avoid using phone when the battery is low
- Avoid using the phone when signal strength is weak
4. What is SAR full form?
SAR means the Specific absorption rate, it is the rate of absorption of Electromagnetic Radiofrequency waves by the body tissue.
5. What are head and body SAR?
SAR is measured at a specific area of the HEAD or BODY, that absorbed the maximum EMRF waves and then averaged over a kilogram.
6. What is mobile SAR?
Mobile phone emits harmful Electromagnetic Radiofrequency waves, SAR(Specific absorption rate) is the rate of absorption of Electromagnetic Radiofrequency waves by the body tissue.
FCC recommends SAR should be at or below 1.6watts/kg averaged over 1gram of tissue.
7. What should mobile phone radiation level be?
There are no specific measures to measure phone radiation. Now you may think about SAR value, SAR value is just a single measurement of a very small part of the radiation that cell phone emits.
8. What is the safest cell phone?
There are many articles and videos, who shows some cell phone brand name in the safest cell phone list. They are judging these phones according to there SAR values but SAR value is just a single measurement of a very small part of the radiation emitted by cell phones.
9. Is SAR value harmful?
SAR means Specific absorption rate, Its actually a measurement of harmful Electromagnetic Radiofrequency waves emitted by cell phones.
10. How is RF radiation measured?
SAR measured at a specific body part of the head and body that absorbed the maximum harmful EMRF waves and then averaged over a kilogram.
