SAR is a measure of the amount of electromagnetic radiation a device emits when in use. This is an important consideration, especially for devices that are held close to the body.

The SAR limit for hand-held mobile devices in Europe is set to 2 W/kg per 10 g of tissue. This standard is specified by the CENELEC and complies with the IEC standards, following the ICNIRP Guidelines 1998.

In the US, the SAR limit is set to 1.6 W/kg per 1 g of tissue. The FCC tests and sets the SAR limits for all mobile devices, which are controlled by the CTIA.

Here's a comparison of the SAR limits in Europe and the US:

Some devices may have higher SAR ratings than others, so it's worth checking the specifications for a particular device to get an idea of its SAR rating.
