Court blocks S.F. warning on cell phones

[William Seger]

12. You are correct; this is horseshit

There is exactly zero credible evidence that cell phones cause cancer, which really comes as no surprise to scientists who actually understand electromagnetic radiation and carcinogens: All known carcinogens cause genetic mutations by damaging DNA, but cellphone microwave photons have about one-millionth the energy required to do that. Known carcinogens include certain chemicals, certain viruses, and radiation with at least the energy of ultraviolet light. No matter how many photons are absorbed, cellphone photons simply do not have the energy required to cause the photoelectric effect, whereby an atom absorbs a photon and emits an electron, which is the only way that photons can break molecular bonds and damage DNA.
