Much of this article fails to acknowledge the difference between radio waves, electro-magnetic waves (EM), and magnetic fields such as what you get from being near a power line. Cell phone signals are EM of far higher frequency, classified as UHF or higher (800 MHz to 3 GHz). Motion of electrons, in other words current flow, creates a magnetic field. Magnetic fields are created by power lines, and any electricity conductor that is exposed to EM waves. Yes, radio waves induce a current in any conductor. That is how an antenna works. Your body is a conductor and therefore can act as an antenna.
Any current, thus any magnetic EM created magnetic field will penetrate your body to some extent. The question is, how deep? There is an effect called Skin Effect. As the frequency goes up, current flow will more and more be on the surface of the conductor. In other words, a cellular signal does not create a magnetic field deep into your body. At the upper range of cellular, most of the current flow will be in the surface one millimetre. http://chemandy.com/calculators/skin-effect-calculator.htm The power grid works at 50-60 Hz. The low frequency was chosen in part to reduce skin effect.
The meter used in this study, an EMDEX Lite is unable to measure any frequency above 1 KHz.
Big fail! http://www.enertech.net/html/EMDEXLiteSpecs.html
So I'm calling this article, and the study prompting your article deeply flawed. Look at the comments following this study.
Animal studies? That will be interesting... I will look for that.
