So Today we will talk about the SAR, friend you had many time heard that your phone can become a culprit for you cancer.... Lets Talk
So what is SAR value is:
SAR=Specific Absorption Rate
So as we all know that in your cell phone there is a antenna tower which used to receive and send signal from the nearest cellular tower, and all these signal are in form of electromagnetic waves, so when it is a electromagnetic wave is must have some power too, so during the proceess for reciiving and sending these signal, the power get radiated, actually these thing happen cause there are some losses occurred during these process (suppose if the process is 100 %, then 80% process would occur and there will be loss of about 20% of the process), so when the antenna is at its full power then the radiation is high (suppose you had turn on the mobile data and also calling at that time radiation is high), so the SAR value is value by which rate out body is receiving the radiation or our body tissue is absorbing the radiation.
SAR value is calculated in two parts one is head and another is body, so when we are at call out head is the nearest body part to ear so it is measured in as head SAR value and another is body where we kept our phone.
In many different countries the government had set a limit of SAR value means if the SAR value of any device is more than the limit then the phone cannot come into market.In India and USA they measure the SAR value by taking 1gm tissue as average and measure the value as 1.6 Watt/Kg means 1.6 Watt/Kg radiation can take for 1 Kg of tissue but in other Europe Union Countries the SAR Value is 2.0 Watt/Kg for 10 gm of tissue.
So when you buy a new phone it do not need to be take care of SAR value as it is down the limit that's why it had come in market as a normal user SAR value does not matter for you, try to take phone by normal SAR value rate if it is not there is no way to tension. Another thing if you are a heavy user like use phone to talk about 12-18 hours in a day, in that case i will recomend you to use a wired headphone to it cause that your phone will be far from your head and radiation rate will be also be less.
At last if you are a normal user no need to be taken care of SAR value and if you are a heavy user use a wired headphone so the radiation rate will be less.
That's all for today
Hope you guys enjoyed
