Cell Phones and People -- The Largest Human Biological Experiment Ever?

Lab rats with cellphones? Our wireless lifestyle is making us all unwitting test subjects.

We love our digital gadgets -- “magic" devices that define cool and promise to remake our lives for the better. But there is growing evidence of a dark side to the techno-magic. Your cellphone, and any other wireless device that depends on electromagnetic (EM) microwave radiation to function, may be hazardous to your health.

Most of the bad news comes from major labs and research institutions in Europe. What they're reporting is that using cellphones and Wi-Fi transmitters -- which operate using similar frequencies -- can have biological effects on the brain and body.

The scientific debate remains heated and far from resolved, as the Health section in The Times reported last week. But the research to date suggests a number of chilling possibilities as to what EM radiation may be doing to us.

For example, in 2008, neuroscientists at Swinburne University of Technology in Australia strapped Nokia phones to subjects' heads, then turned the phones on and off. On -- the brain's alpha waves spiked. Off -- the brain settled. The researchers speculated that the effect was the result of the brain “concentrating to overcome the electrical interference in brain circuits caused by the pulsed microwave radiation."

Swedish neuro-oncologist Leif Salford, chairman of the department of neurosurgery at Lund University, has found that cellphone radiation kills brain cells in rats, especially those cells associated with memory and learning. The damage occurred after an exposure of just two hours. In duplicating earlier research, Salford also found that cellphone microwaves produce holes in the barrier between the circulatory system and the brain in rats. One potential outcome, according to Salford, is dementia.

Meanwhile, Austrian researchers reported in 2004 that cellphone radiation can induce double-strand breaks in DNA, one of the undisputed causes of cancer.

So why isn't this a bigger issue in the U.S.? Partly because there are countervailing studies and other scientists telling us not to be worried, that the risks are low or that we just don't know enough to say that the risks are real.

Consider the biggest study being done on the question of whether cellphones cause cancers of the brain, mouth and ear -- the 13-country Interphone study conducted under the auspices of the International Agency for Research on Cancer in France. The study's epidemiologists have looked at cancer patients and worked backward to establish cellphone habits.

The study, alas, has been fraught with controversy. The multinational researchers -- U.S. scientists conspicuously not among them -- have fallen into warring camps, and the full study has not been released.

However, pieces of the study have been made public. One Interphone study, for example, found that after a decade of cellphone use, the chance of getting a brain tumor goes up as much as 40% for adults. Another Interphone study reported a nearly 300% increased risk of acoustic neuroma, a tumor of the acoustic nerve. But still other Interphone researchers say their data show no increase in brain tumors -- or any tumor -- caused by cellphone use.
