Pro to the question "Is Cell Phone Radiation Safe?"
"I personally dislike cell phones, but can their use lead to cancer?
All known cancer-inducing agents—including [ionizing] radiation, certain chemicals, and a few viruses—act by breaking chemical bonds, producing mutant strands of DNA. Electromagnetic radiation [the kind produced by cell phones] is absorbed by molecules as discrete packets of energy called 'photons.' The energy of a photon is determined by the wavelength; the shorter the wavelength, the higher the energy. Not until the ultraviolet region of the electromagnetic spectrum is reached, beyond visible light, beyond infrared and far, far beyond microwaves, do photons have sufficient energy to break chemical bonds. It's a little like trying to hit an object across a river with a stone... it won't matter how many stones you throw if you can't throw that far. Microwave photons heat tissue, but they do not come close to the energy needed to break chemical bonds, no matter how intense the radiation...
Regardless of how convincing the evidence exonerating cell phones may be, there will continue to be those who will argue that the issue has not been completely settled."
