[2] By 2006 there were 223 million mobile phone users. [3] Mobile phones transmit and receive Radio Frequency (RF) signals in order to communicate. The RF signals from mobile phones fall within the microwave part of the electromagnetic spectrum.[4] This radiation is also referred to as microwave radiation or electromagnetic radiation. In short: Mobile phones use microwave radiation to communicate. Consequently, our landscapes and cities are covered by ‘base stations’ that relay the microwave signals used for communication. Both the base stations and the mobile phones emit microwave radiation. In the last twenty years, the US has adopted mobile phones as a integral part of everyday life; 223 million people have started using personal mobile devices that emit microwave radiation. In order to make this work, there are at least 126,000 cell phone towers that also emit microwave radiation.[5] Could this microwave radiation have a negative impact on our health?
