I wrote an article in 2010 about the harmful effect of radiations from mobile phones and other electronic devices, based on my research then, I pointed out that these devices emit radiations that could be harmful to users of the said devices ( prolong and careless using). In the article, I also mentioned the SAR values of both the United States and that of Europe - 2.0w/kg and 1.6w/kg respectively.
Information on Specific Absorption Rate (SAR) values To communicate with the network, mobile phones emit low levels of radio waves (also known as radiofrequency or 'RF' energy) when being used. Governments around the world have adopted comprehensive international safety guidelines, developed by independent scientific organizations, governing the exposure to RF energy. Mobile phones are designed to operate within these limits.
What is SAR?
SAR stands for Specific Absorption Rate, which is the unit of measurement for the amount of RF energy absorbed by the body when using a mobile phone. The SAR is determined at the highest certified power level in laboratory conditions. However, the actual SAR level of the phone while operating can be well below this value. This is because the phone is designed to use the minimum power required to reach the network. Therefore, the closer you are to a base station, the more likely it is that the actual SAR level will be lower.
Does a lower SAR mean that a phone is safer?
No. Variations in SAR do not mean that there are variations in safety. While there may be differences in SAR levels among phone models, all mobile phones must meet RF exposure guidelines
