electromagnetic field (EMF), electromagnetic radiation (EMR)
All known cancer-inducing agents — including radiation, certain chemicals and a few viruses — act by breaking chemical bonds, producing mutant strands of DNA. 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. Microwave photons heat tissue, but they do not come close to the energy needed to break chemical bonds, no matter how intense the radiation. --Dr. Robert L. Park of the American Physical Society (New York Times Oct. 1, 2002)
Ionizing radiation can break the electron bonds that hold molecules like DNA together and is carcinogenic....The photon energy of cellphone EMF is more than 10 million times weaker than the lowest energy ionizing radiation.--Lorne Trottier
Unless one is willing to discard the concept of photons, Planck's law, and the interaction between photons and atoms—and thus the entire body of quantum physics—it is simply not possible for the photons associated with either a power line or a cell phone to cause cancer."-- S. T. Lakshmikumar
An electromagnetic field (also called electromagnetic radiation) is a region in space through which energy passes that has been created by electrically charged particles. EMFs are produced by such things as power lines, electric appliances, radio waves, and microwaves.
