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 harm-
ful?
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:

The Basics
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.1
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
Appendix C
Consumer Update 83
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
• 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.
