What is sar value ?
SAR (Specific Absorption Rate) is a measure of the amount of radio frequency (RF) energy absorbed by the body when using a mobile phone. It is a way to measure the rate at which energy is absorbed by the body tissue when exposed to radio frequency electromagnetic fields. SAR is typically measured in watts per kilogram (W/kg).
Mobile phone manufacturers are required to test their products and report the SAR value to regulatory authorities in different countries. The SAR value for a mobile phone is usually listed in its user manual or on the manufacturer's website.
The SAR value represents the maximum amount of RF energy that a person can absorb from a mobile phone under laboratory conditions. However, the actual SAR value during normal use can vary depending on factors such as distance from the phone, network signal strength, and usage patterns.
In general, mobile phones with lower SAR values are considered safer, as they emit less RF energy and therefore reduce the potential risk of exposure to harmful radiation. However, it is important to note that there is no conclusive scientific evidence that links mobile phone use to adverse health effects.
The mobile normal sar value ?
Different countries have different regulations and guidelines for SAR values in mobile phones, and these values can vary depending on factors such as frequency band and measurement method. However, in most countries, the maximum SAR value allowed for mobile phones is typically 1.6 W/kg averaged over 1 gram of tissue. This is the SAR limit set by the Federal Communications Commission (FCC) in the United States, and is also used as a reference by many other countries.
It is worth noting that some mobile phone manufacturers voluntarily aim for SAR values that are well below the maximum limit set by regulatory bodies. Additionally, the SAR value of a mobile phone can vary depending on various factors such as network conditions, usage patterns, and environmental conditions, and the actual SAR value during normal use may be lower than the maximum value reported by the manufacturer.
Average mobile head sar value = 1.6 W/Kg measured over 1 gm tissue.
Average mobile body sar value = 1.6 W/Kg measured over 1 gm tissue.
