(Tim) If you or especially your children regularly hold a cellphone to your ear, read this. Then, whenever possible, try to switch to the speakerphone or an earpiece.
I'm right with you in worrying, but a rocket scientist friend of mine likes to point out that there is not enough radiation coming out of a cell phone to create something like a tumor. Compare the following article.
Here are the better bits:
"Cell phones cannot cause cancer, because they do not emit enough energy to break the molecular bonds inside cells. Some forms of electromagnetic radiation, such as x-rays, gamma rays and ultraviolet (UV) radiation, are energetic enough to break the bonds in key molecules such as DNA and thereby generate mutations that lead to cancer. Electromagnetic radiation in the form of infrared light, microwaves, television and radio signals, and AC power is too weak to break those bonds, so we don’t worry about radios, televisions, microwave ovens and power outlets causing cancer.
Where do cell phones fall on this spectrum? According to physicist Bernard Leikind in a technical article in Skeptic magazine (Vol. 15, No. 4), known carcinogens such as x-rays, gamma rays and UV rays have energies greater than 480 kilojoules per mole (kJ/mole), which is enough to break chemical bonds. Green-light photons hold 240 kJ/mole of energy, which is enough to bend (but not break) the rhodopsin molecules in our retinas that trigger our photosensitive rod cells to fire. A cell phone generates radiation of less than 0.001 kJ/mole. That is 480,000 times weaker than UV rays and 240,000 times weaker than green light!
Even making the cell phone radiation more intense just means that there are more photons of that energy, not stronger photons. Cell phone photons cannot add up to become UV photons or have their effect any more than microwave or radio-wave photons can. In fact, if the bonds holding the key molecules of life together could be broken at the energy levels of cell phones, there would be no life at all because the various natural sources of energy from the environment would prevent such bonds from ever forming in the first place."
For those interested. Here is an independant website that shows the radiation levels in the different brands of cell phones: http://www.ewg.org/cellphoneradiation/Get-a-Safer-Phone?allavailable=1
Scientific American pulls a major bait and switch there--by the same "logic" (no cancer without ionizing radiation), we must come to the conclusion that tobacco doesn't cause cancers of the lung, esophagus, nose, and mouth.
There are a lot of other possible causes that could be linked to cell phones--chemicals in the cases, alteration of cellular processes by localized heating, whatever. Thankfully, the statistical data don't suggest that it's a major cause of anything.
Personally, I like the bluetooth headsets where the wearer looks like he's just joined the Borg.
