How to Check Radiation Level on Phone

Cell phones are the way most people are exposed to EMF radiation. The biggest emission of EMF from your phone happens when your wifi and Bluetooth are on. However, the cell phone constantly emits EMFs unless turned off completely. 

This constant exposure to electromagnetic radiation can lead to serious health issues later in life and cause headaches, sleep disturbances, etc. This happens because your body absorbs the radiation you are exposed to, and with your cell phone always near, you are constantly hit with EMFs. That’s why it’s incredibly important to know how to check radiation level on phone.

How to Check Radiation Level on Phone

The best and easiest way to check your phone’s radiation level or its SAR (Specific Absorption Rate) is by dialing *#07# on your phone’s dial pad. After you do it, you will be redirected to your phone’s settings, where you can see the RF exposure. 

Specific Absorption Rate on Your Phone 

Every smartphone emits different levels of radiation, which is why you should check what is the Specific Absorption Rate on your own phone. The SAR value represents the rate at which your body tissue absorbs the electromagnetic waves emitted by your phone. 

The FCC (Federal Communications Commission) regulates the appropriate SAR value for phones. According to these regulations, no phone can have a SAR value of more than 1.6 w/kg of body weight.

In essence, this means that phone manufacturers cannot sell a phone if a test shows that the body absorbs more radiation than 1.6 Watts per kilogram of body weight. The organization has set this rate by closely working with other health and safety agencies, such as the FDA

You can easily check the Specific Absorption Rate on your phone by following the next steps:

  1. First, you should unlock your phone and open the dial pad. 
  2. Next, type in *#07# and dial it. 
  3. After you click the call button on the dial pad, your phone will redirect you to a different part of its settings. 
  4. Here you should click on RF Exposure. 

This code should work on every phone model. The only difference is some phones will show you the SAR code directly after dialing the code. At the same time, others will redirect you first to the settings on your phone. 

Other Ways to Check the Radiation Level on a Phone

Dialing up a code on your phone is not the only way to check its radiation or SAR value. There are many other methods that you can try out alongside the code. You may want to verify that the information you have received is accurate so some of the methods you can try out are:

Visit the FCC website 

Instead of dialing the code on your phone, you can go directly to the FCC website. This will allow you to see the SAR values for different models of cell phones, not only yours. In order to see your phone’s SAR value FCC (Federal Communications Commission) website, you need the grantee code and the product code of your mobile phone. 

All devices have them, which can be found inside your phone’s case, though you might need to take out the battery pack to see them. The codes are often found on the back of cell phones or in the user manual in cases where the battery pack is not detachable. 

Visit the FCC website and follow the directions after discovering the SAR value for your phone. If it exceeds the FCC’s SAR value, you should look for another phone with lower radiation emissions. 

Check the phones official brand website

On their websites, each manufacturer provides information concerning the safety of their products. The SAR information will most likely be accessible in the customer support section or on a particular RF health subpage. 

You will need to know your phone type and serial number, typically printed on a white label inside the device. Therefore, if you are unsure what cell phone you have, you should remove the battery, and the number should be written down inside the phone. The digits will be listed in the user handbook if the battery on your cell phone is not detachable.

Read through the user guide the phone came with

User guides often include information regarding SAR values. If you lost the manual that came with your device, you may find it online and download it to your computer in PDF format.

If you are unsure where to look, enter the model number of your cell phone followed by the phrase “user manual PDF” into a search engine, and you will be able to find the information you need. 

Since every cell phone manufacturer should adhere to the global SAR measuring standard, you will likely find enough details regarding your gadget’s compliance there.

Other Ways to Check the Radiation Level on a Phone

Use Google search 

You can also use Google to find an answer. All you need to do is type in “SAR value alongside your phone model”. This method is most often used by people looking for an answer. However, there are often inaccurate answers online when looking for any information, so there is likely also for the SAR value. 

So you should ensure that the information you get is verified and reliable. However, since this is the quickest way to determine your phone’s SAR rating, most people will first Google the answer before trying out other methods. 

You can use Google to check the SAR value, but I recommend using some of the other methods I listed besides it for more accurate information. 


In conclusion, these are the best methods if you are wondering how to check radiation level on phone. You can use any one of them to get accurate information. You can even use them all to ensure each method has the same answer. 

If you discover that your phone emits too much radiation, meaning its SAR value is too high, you should look for another one. You should avoid exposing your body to too much EMF radiation.
