    How to find out the radiation emission level of a smartphone?

    Have a query about checking radiation level of a smartphone? Looking out for inbuilt feature or any free software which can do so? You can scroll through this page and get to know the best way to check the radiation level of a smartphone.

    I came across a news feed today about a list of smartphones which emit the maximum radiation and those which emit the least, based on a research study. Now, such studies will have sophisticated tools for such research.
    What about the general user?
    Is there any way for me to find out how much radiation is emitted from my phone?
    Is there an inbuilt feature in the phone or some free software that I can use to find out?

    Smartphones are very widely used and penetrated in our life in such a way that no one can think of without it. The use of smartphone may cause health problems. A smartphone with bad SAR is dangerous.
    SAR stands for Specific Absorption Rate. It is a measure of the amount of radio frequency energy that is being absorbed by the body when we use a mobile phone. Federal Communications Commission has indicated safe limits of radio frequency (RF) energy as 1.6 watts per kilogram (1.6 W/kg). The smartphone which are having SAR value equal are less than the limit mentioned above is considered to be safe to use.

    This Radiation level in terms of SAR of smartphone can be obtained by dialing a USSD code*#07#. if result is below 1.6 watts per kilogram (1.6 W/kg) the phone can be considered as safe. Otherwise you have to go for a new phone which will have less than the prescribed value.

    always confident

    Radio Frequency electromagnetic waves are harmful for body especially in amount above the safe limit. There are many other situations where we are exposed to these radiations albeit in controlled doses like MRI scan.

    The effect of these radiations on the body is found with the Specific Absorption Rate (SAR) which is defined as the power absorbed by the unit mass of the body tissue in presence of these types of electromagnetic fields. SAR measurements are done for the electromagnetic frequency range from 10 kHz to 10 GHz. The SAR value will change depending upon the relative position, distance and part of the body exposed to such radiations from the mobile phone.

    As per United States standards the SAR level has to be less than 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of 1 gram of tissue that is absorbing the most signal. European Union stipulates for the EU countries, the SAR limit as or below 2 watts per kilogram (W/kg) averaged over the 10 g of tissue absorbing the most signal. India follows the US standards.

    As already mentioned above in other answer, *#07# code is used to find out the SAR of a particular phone. In some models this code may not work then we have to refer to the detailed manual of the mobile.

    Knowledge is power.
