When purchasing a smartphone, we often check various features such as the camera and processor, but one crucial aspect that might escape our attention is the Specific Absorption Rate (SAR) value. SAR indicates how much radio frequency our body absorbs while using a mobile phone.
Every phone has a designated SAR value, and it is essential to check it because prolonged exposure can have an impact on our body. The SAR value for mobile phones is regulated, and in India, the Department of Telecommunications (DoT) has set a limit of 1.6 watts per kilogram (W/kg) for 1 gram of tissue.
To check the SAR value on your existing phone, you can use a specific code. Dialing *#07# will display separate readings for the head and body on your screen.
For those planning to buy a new phone, it is advisable to manually check the SAR value. Most phones provide this information on the box or in the user manual. Additionally, you can find the SAR value on the company's website. The recommendation to keep phones at a distance from the body is often based on these SAR values.
In conclusion, while focusing on camera quality and processing power is crucial when buying a smartphone, it's equally important to be aware of the device's SAR value. Checking and understanding this value ensures that we are mindful of the potential impact of radio frequency absorption on our bodies.
