Most people while buying a new smartphone go by the specifications or the price of the smartphone. But there are a few other things that one should consider before buying a new smartphone such as after-sales service, resale value or the radiation level.


Having said that, the radiation level is the least known fact or piece of information people want to know before making the purchase. Radiation or SAR value of a phone is basically a radio frequency transmitting device that releases some level of radiation that has an adverse effect on health over time.So, those who want to know the radiation level of their smartphone here’s how to do it.


Any smartphone’s at or below these SAR levels is a “safe” phone, as the measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg) and you want to check the details also in telecom department portal

First things to do:

Some smartphone brands mention the SAR rating in the user manual that comes with the box of the smartphone. However, some smartphone makers simply write down the SAR value in the specification section and on their website. However, there is a simple workaround that allows the users to check the SAR value right inside their phones.

Steps to follow to check the SAR Value:

  1. Unlock your smartphone and open the ‘Dialer’
  2. Now, type the code ‘*#07#
  3. The smartphone will now automatically show the SAR rating of the smartphone

The possible connection between cellphones and cancer is controversial. Many years’ worth of studies on cellphones and cancer have yielded conflicting results. Currently, there’s no consensus about the degree of cancer risk if any posed by cellphone use.

The primary concern with cellphones and cancer seems to be the development of brain tumors associated with cellphone use. A slight increase in the rate of brain tumors since the 1970s, but cellphones weren’t in use during the 1970s.

Instead, such as increased access to medical care and improvements in diagnostic imaging.


  • Another study suggested this mobile radiation a possible increased risk of glioma a specific type of brain tumor for the heaviest cellphone users, but no increase in brain tumor risk overall.
  • The main one study has been followed more than 420,000 smartphone users over 20 year period, researchers found no evidence of a link between cellphones and brain tumors.
  • Another study found an association between cellphones and cancer of the salivary glands. However, only a small number of study participants had malignant tumors.
