Hello, I am concerned at some of the studies which investigate cancer and DNA Damage to brain cells and such. http://www.sciencedaily.com/releases/2004/02/040219075606.htm Now I understand that there is a big hype around the radiation of cellphones potentially causing cancer. It's electromagnetic energy of sorts. The above article claims that Electro-Magnetic energy in the 60 hertz range can cause cell damage to the brain. Is this not the same thing as cancer? Irreversible cell damage which eventually spreads? How can one differentiate between the damage done from Cell Phone Radiation and Electro-Magnetic AC energy? Additionally, It worries me to think that my audio headphones could be doing any sort of damage as well. Does DC power emit an entirely different energy field in terms of what the 60 Hertz AC study was founded on? Any additional reading material would be of great interest. Thank you.
