Final answer:
The SAR limit for the whole body in First Level Mode is 1.6 watts per kilogram. This means that for every kilogram of body weight, the SAR value should not exceed 1.6 watts.
Step-by-step explanation:
The SAR limit for the whole body in First Level Mode refers to the maximum amount of radio frequency (RF) energy that can be absorbed by the human body when using a cell phone. In the United States, the Federal Communications Commission (FCC) requires that the SAR level for a cell phone must be no more than 1.6 watts per kilogram to be certified for sale. This means that for every kilogram of body weight, the SAR value should not exceed 1.6 watts.
For example, if a person weighs 70 kilograms, the SAR level for their whole body should be no more than 112 watts (70 kg x 1.6 watts/kg = 112 watts). This limit is set to ensure that the RF energy absorbed by the body remains below the level that could potentially cause harm.
It's important to note that different cell phone models have different SAR values, so it's recommended to choose a phone with a lower SAR level to minimize RF energy exposure. Therefore the SAR limit for the whole body in First Level Mode is 1.6 watts per kilogram. It is important to choose a cell phone with a lower SAR level to minimize RF energy exposure.
