Introduction: The use of smart phones is increasing in the world. This excessive use, especially in the last two decades, has created too much concern on the effects of emitted electromagnetic fields on human health. This study aims to compare electric field specific absorption rate of head in Nokia and Samsung smart mobile phone users

 Methods: In this descriptive-analytical study the electric fields resulting from Samsung and Nokia smart phones were measured by a portable electromagnetic meter Model HI-3603-VDT/VLF. Then, head absorption rate was calculated by ICNIRP equation. Finally, specific absorption rate for Samsung and Nokia smart phones was compared by T-Test.

Results: The mean of electric field for Samsung and Nokia smart mobile phones was 1.8 ±0.19 v/m  and 2.23±0.39 v/m and  the range of the electric field was 1.56-2.21 v/m  and 1.69-2.89 v/m, respectively. The mean of specific absorption rate in Samsung and Nokia mobile phones was 0.002 ± 0.0005 W/Kg and 0.0041±0.0013 W/Kg at the frequency of 900 MHz and 0.004±0.001 W/Kg and 0.0062±0.0002  W/Kg at the frequency of 1800 MHz, respectively. The ratio of mean electronic field to provide guidance in the Samsung mobile phone at the frequency of 900 MHz and 1800 MHz was 4.36% and 3.34%, respectively, while it was 5.62% and 4.31% in the Nokia mobile phone. The ratio of mean head specific absorption rate to provide guidance at the frequency of 900 was 0.15% and 0.25% and at the frequency of 1800 MHz was 0.23 %and 0.38% for respectively Samsung and Nokia mobile phones.

Conclusion: The rate of electric field specific absorption of Nokia smart mobile phones at the frequencies of 900 and 1800 is significantly higher than Samsung. Therefore, it can be concluded that Nokia smart mobile phone users are exposed to higher related health risks in comparison to Samsung smart mobile phone users.
