For epidemiological studies on the possible association between mobile phone use and brain diseases, representative phone models had been numerically implemented based on the specific absorption rate (SAR) distributions and spatial peak 1-g SAR values from the SAR test reports of mobile phones released...
Mobile phones are low-powered radiofrequency transmitters and they operate at frequencies between 450 MHz and 6 GHz and their peak powers are from 0.1 to 2 watts. Mobile phone transmits power when it is turned on and the SAR value falls when increasing the distance to the user. For example...
Although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. This is because GSM phones are designed to operate at multiple power levels so as to use only the power required to reach the network...
SAR exposure limits differ between the countries/regions, the following table provides mobile phones’ SAR limits of various countries. Country Certification SAR Limit United States FCC 1.6 W/Kg Canada ISED 1.6 W/Kg European Union CE 2.0 W/Kg The FCC (US) has set some guidelines to restrict...

The Ministry of Information and Communication (MIC) of Vietnam issued a Draft Circular which promulgates national technical regulations on Specific Absorption Rates (SAR) for Mobile Phones on April 25, 2024. The Draft Circular will come into effect on July 1, 2025, at which point imported and...
Since most people aren’t willing to give up their mobile phone, it seems logical that knowing the SAR value of the top selling cell phones would be a good idea. That way you could take the SAR into consideration when buying your next cell phone. In order to compare brands and models,...
Human exposure to electromagnetic fields emitted by mobile phones is characterised by the Specific Absorption Rate (SAR). This value corresponds to the RF power absorbed by unitary mass of the equivalent tissue. It represents the basic restriction used to define limit of human exposure to RF ...

While there may be differences between the SAR levels of various phones, all mobile phones granted an FCC equipment authorization meet the government requirement for safe exposure. SAR information on this phone model is on file at the FCC and can be found under the Display Grant section of ...
