APPENDIX C: CONSUMER UPDATE
Consumer Update on Mobile Phones (Published by U.S. Food and Drug Administration,
Center for Devices and Radiological Health, October
20, 1999.)
FDA has been receiving inquiries about the safety
of mobile phones, including cellular phones and
PCS phones. The following summarizes what is
known—and what remains unknown—about
whether these products can pose a hazard to
health, and what can be done to minimize any
potential risk. This information may be used to
respond to questions.
Why the concern? Mobile phones emit low levels of radiofrequency
energy (i.e., radiofrequency radiation) in the
microwave range while being used. They also
emit very low levels of radiofrequency energy
(RF), considered non-significant, when in the
stand-by mode. It is well known that high levels of
RF can produce biological damage through
heating effects (this is how your microwave oven
is able to cook food). However, it is not known
whether, to what extent, or through what
mechanism, lower levels of RF might cause
adverse health effects as well. Although some
research has been done to address these
questions, no clear picture of the biological
effects of this type of radiation has emerged to
date. Thus, the available science does not allow
us to conclude that mobile phones are absolutely
safe, or that they are unsafe. However, the
available scientific evidence does not
demonstrate any adverse health effects
associated with the use of mobile phones.
What kind of phones are in question? Questions have been raised about hand-held
mobile phones, the kind that have a built-in
antenna that is positioned close to the user’s
head during normal telephone conversation.
These types of mobile phones are of concern
because of the short distance between the
phone’s antenna — the primary source of the RF
— and the person’s head. The exposure to RF
from mobile phones in which the antenna is
located at greater distances from the user (on the
outside of a car, for example) is drastically lower
than that from hand-held phones, because a
person’s RF exposure decreases rapidly with
distance from the source. The safety of so-called
“cordless phones, which have a base unit
connected to the telephone wiring in a house and
which operate at far lower power levels and
frequencies, has not been questioned. 
How much evidence is there that hand-
held mobile phones might be harmful?
Briefly, there is not enough evidence to know for
sure, either way; however, research efforts are
on-going. The existing scientific evidence is
conflicting and many of the studies that have
been done to date have suffered from flaws in
their research methods. Animal experiments
investigating the effects of RF exposures
characteristic of mobile phones have yielded
conflicting results. A few animal studies, however,
have suggested that low levels of RF could
accelerate the development of cancer in
laboratory animals. In one study, mice genetically
altered to be predisposed to developing one type
of cancer developed more than twice as many
such cancers when they were exposed to RF
energy compared to controls. There is much
uncertainty among scientists about whether
results obtained from animal studies apply to the
use of mobile phones. First, it is uncertain how to
apply the results obtained in rats and mice to
humans. Second, many of the studies that
showed increased tumor development used
animals that had already been treated with
cancer-causing chemicals, and other studies
exposed the animals to the RF virtually
continuously — up to 22 hours per day.
For the past five years in the United States, the
mobile phone industry has supported research
into the safety of mobile phones. This research
has resulted in two findings in particular that merit
additional study:
1. In a hospital-based, case-control study, researchers
looked for an association between mobile phone use and
either glioma (a type of brain cancer) or acoustic neuroma
(a benign tumor of the nerve sheath). No statistically
significant association was found between mobile phone
use and acoustic neuroma. There was also no association
between mobile phone use and gliomas when all types of
gliomas were considered together. It should be noted that
the average length of mobile phone exposure in this study
was less than three years.
When 20 types of glioma were considered separately,
however, an association was found between mobile phone
use and one rare type of glioma, neuroepithelliomatous
tumors. It is possible with multiple comparisons of the
same sample that this association occurred by chance.
Moreover, the risk did not increase with how often the
mobile phone was used, or the length of the calls. In fact,
the risk actually decreased with cumulative hours of mobile
phone use. Most cancer causing agents increase risk with
increased exposure. An ongoing study of brain cancers by
the National Cancer Institute is expected to bear on the
accuracy and repeatability of these results.

2. Researchers conducted a large battery of laboratory tests
to assess the effect of exposure to mobile phone RF on
genetic material. These included tests for several kinds of
abnormalities, including mutations, chromosomal
aberrations, DNA strand breaks, and structural changes in
the genetic material of blood cells called lymphocytes.
None of the tests showed any effect from the RF except for
the micronucleus assay, which detects structural effects on
the genetic material. The cells in this assay showed
changes after exposure to simulated cell phone radiation,
but only after 24 hours of exposure. It is possible that
exposing the test cells to radiation for this long resulted in
heating. Since this assay is known to be sensitive to
heating, heat alone could have caused the abnormalities to
occur. The data already in the literature on the response of
the micronucleus assay to RF are conflicting. Thus, follow-
up research is necessary.
2
FDA is currently working with government,
industry, and academic groups to ensure the
proper follow-up to these industry-funded
research findings. Collaboration with the Cellular
Telecommunications Industry Association (CTIA)
in particular is expected to lead to FDA providing
research recommendations and scientific
oversight of new CTIA-funded research based on
such recommendations. 
Two other studies of interest have been reported 
recently in the literature:
1. Two groups of 18 people were exposed to simulated
mobile phone signals under laboratory conditions while
they performed cognitive function test. There were no
changes in the subjects’ ability to recall words, numbers, or
pictures, or in their spatial memory, but they were able to
make choices more quickly in one visual test when they
were exposed to simulated mobile phone signals. This was
the only change noted among more than 20 variables
compared.
3
2. In study of 209 brain tumor cases and 425 matched
controls, there was no increased risk of brain tumors
associated with mobile phone use. When tumors did exist
in certain locations, however, they were more likely to be
on the side of the head where the mobile phone was used.
Because this occurred in only a small number of cases, the
increased likelihood was too small to be statistically
significant.
4
In summary, we do not have enough information
at this point to assure the public that there are, or
are not, any low incident health problems
associated with use of mobile phones. FDA
continues to work with all parties, including other
federal agencies and industry, to assure that
research is undertaken to provide the necessary
answers to the outstanding questions about the
safety of mobile phones. 
What is known about cases of human 
cancer that have been reported in users of 
handheld mobile phones? 
Some people who have used mobile phones
have been diagnosed with brain cancer. But it is
important to understand that this type of cancer
also occurs among people who have not used
mobile phones. In fact, brain cancer occurs in the
U.S. population at a rate of about 6 new cases
per 100,000 people each year. At that rate,
assuming 80 million users of mobile phones (a
number increasing at a rate of about 1 million per
month), about 4800 cases of brain cancer would
be expected each year among those 80 million
people, whether or not they used their phones.
Thus it is not possible to tell whether any
individual’s cancer arose because of the phone,
or whether it would have happened anyway. A
key question is whether the risk of getting a
particular form of cancer is greater among people
who use mobile phones than among the rest of
the population. One way to answer that question
is to compare the usage of mobile phones among
people with brain cancer with the use of mobile
phones among appropriately matched people
without brain cancer. This is called a case-control
study. The current case-control study of brain
cancers by the National Cancer Institute, as well
as the follow-up research to be sponsored by
industry, will begin to generate this type of
information.
What is FDA’s role concerning the safety of 
mobile phones? 
Under the law, FDA does not review the safety of
radiation-emitting consumer products such as
mobile phones before marketing, as it does with
new drugs or medical devices. However, the
agency has authority to take action if mobile
phones are shown to emit radiation at a level that
is hazardous to the user. In such a case, FDA
could require the manufacturers of mobile phones
to notify users of the health hazard and to repair,
replace or recall the phones so that the hazard no
longer exists.
Although the existing scientific data do not justify
FDA regulatory actions at this time, FDA has
urged the mobile phone industry to take a number
of steps to assure public safety. The agency has
recommended that the industry:
 support needed research into possible
biological effects of RF of the type emitted by
mobile phones;
 design mobile phones in a way that minimizes
any RF exposure to the user that is not
necessary for device function; and  
						

							Appendix C: Consumer Update    99
 cooperate in providing mobile phone users
with the best possible information on what is
known about possible effects of mobile phone
use on human health.
At the same time, FDA belongs to an interagency
working group of the federal agencies that have
responsibility for different aspects of mobile
phone safety to ensure a coordinated effort at the
federal level. These agencies are:
 National Institute for Occupational Safety and
Health
 Environmental Protection Agency
 Federal Communications Commission
 Occupational Health and Safety Administration
 National Telecommunications and Information
Administration
The National Institutes of Health also participates
in this group.
In the absence of conclusive information 
about any possible risk, what can 
concerned individuals do? 
If there is a risk from these products — and at this
point we do not know that there is — it is probably
very small. But if people are concerned about
avoiding even potential risks, there are simple
steps they can take to do so. For example, time is
a key factor in how much exposure a person
receives. Those persons who spend long periods
of time on their hand-held mobile phones could
consider holding lengthy conversations on
conventional phones and reserving the hand-held
models for shorter conversations or for situations
when other types of phones are not available.
People who must conduct extended
conversations in their cars every day could switch
to a type of mobile phone that places more
distance between their bodies and the source of
the RF, since the exposure level drops off
dramatically with distance. For example, they
could switch to
 a mobile phone in which the antenna is located
outside the vehicle,
 a hand-held phone with a built-in antenna
connected to a different antenna mounted on
the outside of the car or built into a separate
package, or 
 a headset with a remote antenna to a mobile
phone carried at the waist.
Again, the scientific data do not
 demonstrate that
mobile phones are harmful. But if people are
concerned about the radiofrequency energy from
these products, taking the simple precautions
outlined above can reduce any possible risk.
