What is SAR Value?

SAR (Specific Absorption Rate) is a measurement that indicates how much radiofrequency (RF) energy your body absorbs when using a mobile device such as a smartphone.

What Does SAR Measure?

SAR measures the amount of radiation that human tissue absorbs from a wireless device when it’s operating at its highest power. It’s expressed in watts per kilogram (W/kg).

How is SAR Tested?

Measured over either 1 gram or 10 grams of simulated tissue

Conducted under maximum signal conditions

Separate values are provided for head and body exposure

What is a Safe SAR Level?

US FCC Limit: 1.6 W/kg over 1g of tissue

EU Limit (ICNIRP): 2.0 W/kg over 10g of tissue

Turkey follows EU standard: 2.0 W/kg

Any device with SAR below these limits is considered safe — but the lower the SAR, the better.

Where Can You Find SAR Info?

On product packaging or user manual

On the manufacturer’s website

In the device settings menu (About section)

On official telecom regulatory databases

Should You Prefer Low SAR Devices?

Yes. When choosing between two similar devices, the one with the lower SAR offers better long-term safety with respect to radiation exposure.

Tips to Reduce Radiation Exposure

Use headphones or speaker mode for calls

Don’t sleep with the phone near your head

Avoid carrying it close to your body for long durations

Refrain from calling while charging

Weak signal = higher radiation → keep your phone away in such cases
