➤ What is SAR value?                                                                                                         

Specific Absorption Rate

                        


Specific Absorption Rate(SAR) is the rate at which tissue of the human body absorbs radiation or energy radiated by mobile phones or other devices, having a unit watt per kilogram(w/kg). All mobile phone has an antenna which receives and sends signals. As we know all the signals are electromagnetic waves i.e. it is a form of energy. When a mobile phone sends or receives a signal there is a loss of signal (energy) due to some hindrance such as the environment in this exchange and this energy spreads nearby in the environment. It is impossible to send or receive 100% of the signal. When the mobile phone antenna works at its full capacity such as you are talking to someone and Wifi, Hotspot, Bluetooth and internet data is on than the amount of radiation is increased, which means when you doing a lite work, radiation will be low and during heavy work, radiation will be high.

how to check sar value


➤How to check the SAR value of your phone:-   To check the SAR value just do the following steps 
  1. Open the dial pad of the mobile phone
  2. dial *#07#
  3. scroll down and  click on IN and check the maximum and minimum SAR value 



There are 4 other ways to check SAR value:-
1. In the mobile phone settings
2. In the user manual
3. On the website that collects SAR values of different phones
4. On the website of the mobile phone manufacturer

➤Here is the link for some mobile phone manufacturers:

Samsung, Sony, Huawei, Apple, LG, and Motorola

Every country has there specific SAR value. India and USA have the same SAR value which is 1.6 watts/kg which means 1kg of tissue will absorb 1.6 watts of energy. European Union has a different SAR value from India and USA. 

If any phone is having SAR value more than a specific value then that mobile phone manufacturer cannot sell their phone in that very country. So, it is necessary that every phone should have a SAR value less than the specific value.

Here is the SAR value of some popular smartphones.
iPhone 6:  1.59 W/kg
LG G3: 0.99 W/kg
LG G2: 1.44 W/kg
Samsung Galaxy Note 2: 0.42 W/kg
Samsung Galaxy Note 3: 1.07 W/kg
Samsung Galaxy Note 4: 1.20 W/kg
Samsung Galaxy S5: 1.28 W/kg
HTC One (M8): 1.29 W/kg

➤Is radiation harmful to health?:- Answer to this question depends on in what manner you are using your phone. If you talk for more than 2-3 hours daily then it will make the wrong impact on your health. You may suffer from brain tumours or cancer-like diseases. So use headphones when you talk to someone on the mobile phone and don't use the phone for a long time.
