Okay, so a few cells were negatively effected after 24 hours of steady bombardment. Who uses a
cell phone that much? What would this affect? The hair on my ear? The real issue is that no
permanent damage to a larger organism is possible. If anything, this would raise questions about
what the effects of all the radio bombardment we are contantly being exposed to is doing to us.
This article fails to show a danger from typical cell phone usage, not when everything is reversed
in short order.

Cancer Cell Study Revives Cell Phone Safety Fears

The safety of cell phones has been brought into question once again by research that suggests
radio waves from the devices could promote the growth of tumors. Paradoxically, the study suggests
that the radiation makes tumors grow more aggressively by initially killing off cancer cells.

Cell Biologist Fiorenzo Marinelli and his team at the National Research Council in Bologna, Italy,
decided to investigate whether radio waves had any effect on leukemia cells after previous studies
indicated that the disease might be more common among mobile phone users. The life cycle of
leukemia cells is well understood, making it relatively easy to spot changes in behavior.

The team exposed leukemia cells in the lab to 900-megahertz radio waves at a power level of 1
milliwatt and then looked at the activity of a gene that triggers cell suicide. Many European
mobile networks operate at 900 megahertz, and maximum power outputs are typically 2 watts,
although they regularly use only one-tenth of this power.

After 24 hours of continuous exposure to the radio waves, the suicide genes were turned on in far
more leukemia cells than in a control population that had not been exposed. What is more, 20
percent more exposed cells had died than in the controls.

But after 48 hours exposure, the apparently lethal effect of the radiation went into reverse.
Rather than more cells dying, Marinelli found that a survival mechanism kicked in. Three genes
that trigger cells to multiply were turned on in a high proportion of the surviving cells, making
them replicate ferociously. The cancer, although briefly beaten back, had become more aggressive.

DNA damage?

Marinelli presented his results this month at the International Workshop on Biological Effects of
Electromagnetic Fields on the Greek island of Rhodes. While the results do not show a direct
health threat from mobile phones, they provide fresh evidence that radiation from such devices
could play an important role in activating genes that might help cancer cells thrive.

"We don't know what the effects would be on healthy human cells," says Marinelli, "but in leukemia
cells the response is always the same." Marinelli suspects the radiation may initially damage DNA,
and that this interferes with the cells' biochemical signals in a way that ultimately triggers a
defensive mechanism.

Many scientists believe that because radiation from cell phones does not have enough energy to
break chemical bonds, it cannot damage cells. The only way damage could occur, they say, is if the
radio waves heated tissues up.

But British research earlier in 2002, by Molecular Toxicologist David de Pomerai at the University
of Nottingham, showed that radio waves can cause biological effects that are not due to heating.
He found that nematode worms exposed to radio waves showed an increase in fertility-the opposite
effect from what would be expected from heating.

"Confused field"

Marinelli's study is intriguing, says de Pomerai. "But I'm far from convinced that these authors
are looking at any reproducible and real phenomena," he says. Other studies have shown mobile
phone radiation to have no effect on cell death, de Pomerai adds.

An inquiry in April 2000 by the British government found no evidence of any health risks from
mobile phones. But it still recommended that people take a precautionary approach until further
evidence emerged. In particular, it suggested children, whose brains are still developing, should
not use mobile phones excessively.

"It's a very confused field," admits Colin Blakemore, a physiologist at the University of Oxford
and a member of the British National Radiological Protection Board's advisory group on non-
ionizing radiation. People should place more reliance on animal studies than lab-based experiments
on cells, he says.

But de Pomerai insists that a consensus is emerging that non-ionizing radiation can indirectly
damage DNA by affecting its repair system. If the DNA repair mechanism does not work as well as it
should, mutations in cells could accumulate with disastrous consequences. "Cells with unrepaired
DNA damage are likely to be far more aggressively cancerous," he says
