We've seen so many chapters of the "dangerous / not dangerous" chronicles with regard to cellphone radiation that we've lost count, but thanks to a Danish study recently carried out on 420,000 avid mobile users, we can finally put those worries to rest (we hope). While it's no secret that mobile phone antennas emit "electromagnetic fields that can penetrate the human brain," we've been yearning for a study such as this to quiet the tin-foil advocates (and ensure our own safety). Researchers from the Danish Institute of Cancer Epidemiology in Copenhagen looked at data on people who had been using mobile phones "from as far back as 1982" in order to draw their conclusions, and after all was said and done, they found "no evidence to suggest users had a higher risk of tumors in the brain, eye, or salivary gland, or developing leukemia." Thankfully, a similar study published earlier this year by the Institute of Cancer Research also concluded that mobile phone use "was not associated with a greater risk of brain cancer." So, there you have it folks, you can safely yap away without fear of mutating into some form of diseased being -- until the next study "proves" otherwise, of course.
