Week of September 27, 2000
With 100 million Americans using cell phones, there's a great
deal of interest in how their use affects the human body - and
very little accurate information. In this hour, we hear from the
top federal regulator as well as a journalist reporting on cell
phone health effects. We also look at the impact on cell phones
on the human psyche, and the etiquette of mobile phone use. Guests
include: Dr. David Feigal of the U.S. Food and Drug Administration;
Dr. Louis Slesin, editor of Microwave News; Dr. Lilli Friedland,
an expert in the psychology of new technologies; reigning Mrs.
Palm Beach County Jacqueline Whitmore, who runs the Protocol
School of Palm Beach; and Dr. Charles Jennings, editor
of the scientific journal Nature Neuroscience. Commentary by John
Hockenberry.
We begin the hour with commentary by host Dr.
Fred Goodwin, who observes that, as a psychiatrist, he
thinks of the moon when considering the effect of electromagnetic
radiation on the brain. Serious scientific evidence has demonstrated
that lunar cycles cause a measurable shift in the electricity
of the brain, he says, leading him to wonder why cell phones wouldn't,
too. The field of cell phone research has produced few answers
to date, he says.
Next, some New York teen-agers talk about cell phones as a fashion
statement . and a parental leash.
Joining the program next is Dr.
David Feigal, a physician and clinical epidemiologist and
director of the U.S. Food and Drug Administration's Center for
Devices and Radiological Health. The FDA is responsible for overseeing
cell phone safety through a complicated joint arrangement with
several other federal agencies, including the Federal Communications
Commission. The FDA's formal position is that science has not
demonstrated adverse health effects from cell phone use, but that
it is not possible at present to conclude that mobile phones are
either safe, or unsafe.
Feigal says that the FDA is responsible for setting the levels
of radiation that cell phones can emit into the skull and brain.
The FDA's strategy, he says, is to monitor the research in to
cell phone safety. While officials have concluded that studies
do not currently demonstrate a health risk, they do try to let
concerned consumers know what they can do to reduce any potential
of a problem.
Feigal says the research he's reviewed regarding the biological
impact of cell phones shows only subtle effects, and that they
are hard to replicate. It's difficult to know whether there is
just a small effect or none at all, he says.
The discussion is joined by Lynne, a caller from Georgia, who
wants to know about levels of radiation from cellular transmission
towers. There's a tower right over her child's preschool, she
says, and near a kindergarten playground. Feigal says that the
radiation levels from such towers are low and quickly dissipated.
The caller also asks what we know about the impact of this type
of radiation on children. Dr. Goodwin observes that teen-agers
spend a huge amount of time on the phone, and that their brains
and nervous systems are still developing. Plus, those who begin
using cell phones as a child can expect a lifetime of exposure,
Goodwin says. Feigal says the radiation exposure from a cellular
tower would be far lower than allowing the child to use the family
cell phone. He goes on to acknowledge that there has been very
little research conducted to date on the risk to kids of the actual
phones themselves, which emit heat as well as electromagnetic
radiation.
Goodwin next asks his guest what studies he'd like to see replicated.
Feigal says he's interested in seeing more research that explores
the long-term impact on memory, since there's some anecdotal evidence
of some individual problems. There's no way of knowing right now
whether some people are just particularly sensitive, perhaps because
of a medical condition, or whether the effects are more generic.
Feigal says that some of the responsibility lies with the consumer.
He asks: Do we keep products off the market until all the answers
are in? People think if FDA has approved something, it means that
it's safe, he says, when many things, especially drugs, do carry
some degree of risk.
Feigal says that a new consumer demand that exposure levels are
kept low will put pressure on cell phone manufacturers to revamp
their designs. In response to a question, Feigal says that he
personally, would prefer a phone that allowed the antenna to extend
away from his body. Asked how consumers can compare between various
models, he acknowledges that the FDA should probably be doing
a better job providing consumer information, and also mentions
an article in WIRED magazine that did compare various brands
and models.
People worried about the risk of exposure should keep the duration
of their calls down, and consider using a hands-free earpiece/microphone
headset, he suggests. The Federal Communications Commission maintains
a website with highly technical
information on the radiation output of various models of cell
phones. And

A completely different perspective is offered next by Dr.
Louis Slesin, editor of Microwave
News, a bimonthly newsletter that covers news about electromagnetic
radiation. Slesin says there is little research going on in the
U.S. about cell phone safety, and that studies abroad suggesting
health risks are, for the most part, ignored here. He discusses
a number of studies that he says point to problems, including:
- An experiment in Australia a
few years ago, funded by the Australian telecommunications industry,
which exposed mice to simulated cell phone radiation for 18
months, with two 30-minunte sessions a day. The study found
that the exposed mice had more than a doubling of the cancer.
The cell phone industry here has performed no animal studies
to date although the FDA has requested them in writing.
- Cognitive studies in three different
labs, in The UK, Finland and Germany, which suggest that cell
phone radiation may speed up brain function, allowing test subjects
to perform certain tasks faster. Although may sound positive,
Slesin says, the question is: If cell phone radiation is having
that biological effect, what other effects is it having?
- A Swedish study, which showed
some correlation between side of the head in which brain tumors
developed and side on which the patient held a cell phone. While
the results of that study were not statistically significant,
Slesin says, it does seem to warrant further investigation.
- Various studies in Europe indicating
sleep disturbances.
The issue of biological effects
from cell phones became an issue about seven years ago, Slesin
says, when a man filed a lawsuit charging that his wife had died
of a brain tumor related to cell phone use. Shortly thereafter,
the industry committed to spending $25 million in research on
cell phone health effects. Slesin says his publication, Microwave
News, has not been able to learn how that money was spent.
Slesin suggests that it's important
for researchers to learn soon how the radiation is mechanistically
interacting with the human body. At present, we don't know, and
no one in the U.S. is doing these important studies, he says.
In 1990, one of the very first studies, government -supported,
found that tumor cells grew much more rapidly when exposed to
cell phone radiation, Slesin says, adding that he's amazed that
no one has ever attempted to replicate those results.
His advice for consumers: Don't
give cell phones to kids until we know more about the effects,
and use hands-free sets whenever possible. Keep the antenna as
far as possible from the body . Don't clip it to your belt or
put it in your pocket; set the phone itself on a desk or table,
or hold it away from the body. The radiation exposure quickly
dissipates as the antenna is moved away from the body, he says.

Turning from the effects on the
body to the effects on the psyche, Dr. Goodwin is joined by Dr.
Lilli
Friedland, a clinical psychologist and specialist
in media psychology, who has headed a New Technologies Committee
for the American Psychological Association; and Jacqueline
Whitmore, who owns and operates the Protocol School of
Palm Beach, Fla. which consults to industry and individuals on
the fine points of civility and etiquette. Mrs. Whitmore is also
the reigning Mrs. Palm Beach County.
Friedland says that she is concerned
that people are starting to substitute cell phones conversations
for real intimacy. It's hard to resolve differences, or learn
to be social, using cell phone communications or email, she suggests.
In addition, people use cell phones at inappropriate times and
in inappropriate locations, she says, observing that while we
judge ourselves by our intentions, we judge others by their behavior.
While we might think that we're just chatting on the phone for
a moment, the person we're with may well view it as a rude interruption,
the psychologist says.
Whitmore agrees and says she encounters
a growing need for education in cell phone etiquette. Some of
her commonsense rules: Don't use them in hospitals, films, weddings,
funerals or public restrooms. In a restaurant, if you're expecting
an important call, let your dinner partners know in advance. Step
away from the table to take the call, and be brief.

Protocol School of Palm Beach online, write to them at Post
Office Box 3073, Palm Beach, Florida 33480, or call 888-968-3460.
Next, commentator John
Hockenberry speculates that cell phones may actually reflect
a trend in human evolution, observing that people are still talking
into the air on the streets of New York - and that we still have
no idea to whom.
Finally, changing directions, we
hear from Dr. Charles Jennings,
editor of the scientific journal Nature
Neuroscience. He talks about new developments in the use of
PET scans to chart emotions and about new research into Alzheimer's
disease.
