1. Do wireless phones pose a
health hazard? 
The available scientific evidence
does not show that any health
problems are associated with
using wireless phones. There is
no proof, however, that wireless
phones are absolutely safe.
Wireless phones emit low levels
of radiofrequency energy (RF) in
the microwave range while being
used. They also emit very low
levels of RF when in the Home
screen. Whereas high levels of RF
can produce health effects (by
heating tissue), exposure to low
level RF that does not produce
heating effects causes no known
adverse health effects. Many
studies of low level RF exposures
have not found any biological
effects. Some studies have
suggested that some biological
effects may occur, but such
findings have not been confirmedby additional research. In some
cases, other researchers have had
difficulty in reproducing those
studies, or in determining the 
						

							Safety Guidelines
74
Safety Guidelines
reasons for inconsistent results.  
2. What is the FDA’s role
concerning the safety of
wireless phones? 
Under the law, the FDA does not
review the safety of
radiationemitting consumer
products such as wireless phones
before they can be sold, as it
does with new drugs or medical
devices. However, the agency has
authority to take action if
wireless phones are shown to
emit radiofrequency energy (RF)at a level that is hazardous to the
user. In such a case, the FDA
could require the manufacturers
of wireless 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,
the FDA has urged the wirelessphone industry to take a number
of steps, including the following: 
Support needed research into
possible biological effects of
RF of the type emitted by
wireless phones; 
Design wireless phones in a
way that minimizes any RFexposure to the user that is
not necessary for device
function; and 
Cooperate in providing users
of wireless phones with the
best possible information on
possible effects of wireless
phone use on human health. 
The FDA belongs to an
interagency working group of
the federal agencies that have
responsibility for different
aspects of RF safety to ensure
coordinated efforts at the
federal level. The following 
						

							75
Safety Guidelines
agencies belong to this
working group: 
National Institute for
Occupational Safety and
Health 
Environmental Protection
Agency 
Occupational Safety and
Health Administration
(Administración de la
seguridad y salud laborales) 
Occupational Safety and
Health Administration 
National Telecommunications
and Information
Administration 
The National Institutes of Health
participates in some interagencyworking group activities, as well. 
The FDA shares regulatory
responsibilities for wireless
phones with the FederalCommunications Commission
(FCC). All phones that are sold
in the United States must comply
with FCC safety guidelines that
limit RF exposure. The FCC relies
on the FDA and other health
agencies for safety questions
about wireless phones. 
The FCC also regulates the base
stations that the wireless phone
networks rely upon. While these
base stations operate at higher
power than do the wireless
phones themselves, the RF
exposures that people get from
these base stations are typically
thousands of times lower than
those they can get from wireless
phones. Base stations are thus
not the subject of the safety
questions discussed in this
document. 
3. What kinds of phones are
the subject of this update?
The term ‘wireless phone’ refers 
						

							Safety Guidelines
76
Safety Guidelines
here to handheld wireless phones
with builtin antennas, often
called ‘cell’, ‘mobile’, or ‘PCS’
phones. These types of wireless
phones can expose the user to
measurable radiofrequency
energy (RF) because of the short
distance between the phone and
the user’s head. These RF
exposures are limited by FCC
safety guidelines that were
developed with the advice of the
FDA and other federal health and
safety agencies. When the phone
is located at greater distances
from the user, the exposure to RF
is drastically lower because a
person’s RF exposure decreases
rapidly with increasing distance
from the source. The socalled
‘cordless phones,’ which have a
base unit connected to the
telephone wiring in a house,typically operate at far lower
power levels, and thus produce
RF exposures far below the FCC
safety limits. 4. What are the results of the
research done already?
The research done thus far has
produced conflicting results, and
many studies have suffered from
flaws in their research methods.
Animal experiments investigating
the effects of radiofrequency
energy (RF) exposures
characteristic of wireless phones
have yielded conflicting results
that often cannot be repeated in
other laboratories. A few animal
studies, however, have suggested
that low levels of RF could
accelerate the development of
cancer in laboratory animals.
However, many of the studies
that showed increased tumor
development used animals that
had been genetically engineered
or treated with cancer causing
chemicals so as to be pre
disposed to develop cancer in
the absence of RF exposure.
Other studies exposed the 
						

							77
Safety Guidelines
animals to RF for up to 22 hours
per day. These conditions are
not similar to the conditions
under which people use wireless
phones, so we don’t know with
certainty what the results of such
studies mean for human health.
Three large epidemiology studies
have been published since
December 2000. Between them,
the studies investigated any
possible association between the
use of wireless phones and
primary brain cancer, glioma,
meningioma, or acoustic
neuroma, tumors of the brain or
salivary gland, leukemia, or other
cancers. None of the studies
demonstrated the existence of
any harmful health effects from
wireless phone RF exposures.
However, none of the studies can
answer questions about longterm exposures, since the
average period of phone use in
these studies was around threeyears. 
5. What research is needed to
decide whether RF exposure
from wireless phones poses a
health risk? 
Acombination of laboratory
studies and epidemiological
studies of people actually using
wireless phones would provide
some of the data that are
needed. Lifetime animal exposure
studies could be completed in a
few years. However, very largenumbers of animals would be
needed to provide reliable proof
of a cancer promoting effect if
one exists. Epidemiological
studies can provide data that is
directly applicable to human
populations, but 10 or more
years followup may be needed
to provide answers about some
health effects, such as cancer.
This is because the interval
between the time of exposure to 
						

							Safety Guidelines
78
Safety Guidelines
a cancercausing agent and the
time tumors develop  if they do
may be many, many years. The
interpretation of epidemiological
studies is hampered by
difficulties in measuring actual RF
exposure during daytoday use
of wireless phones. Many factors
affect this measurement, such as
the angle at which the phone is
held, or which model of phone is
used. 
6. What is the FDA doing to
find out more about the
possible health effects of
wireless phone RF? 
The FDA is working with the U.S.
National Toxicology Program and
with groups of investigators
around the world to ensure that
high priority animal studies are
conducted to address important
questions about the effects of
exposure to radiofrequency
energy (RF). The FDA has been aleading participant in the World
Health Organization International
Electromagnetic Fields (EMF)
Project since its inception in
1996 . An influential result of
this work has been the
development of a detailed
agenda of research needs that
has driven the establishment of
new research programs around
the world. The project has also
helped develop a series of public
information documents on EMF
issues. The FDA and the Cellular
Telecommunications & Internet
Association (CTIA) have a formal
Cooperative Research and
Development Agreement
(CRADA) to do research on
wireless phone safety. The FDA
provides the scientific oversight,
obtaining input from experts in
government, industry, and
academic organizations. CTIA
funded research is conducted
through contracts with 
						

							79
Safety Guidelines
independent investigators. The
initial research will include both
laboratory studies and studies of
wireless phone users. The
CRADA will also include a broad
assessment of additional
research needs in the context of
the latest research developments
around the world.
7. How can I find out how much
radio frequency energy
exposure I can get by using
my wireless phone? 
All phones sold in the United
States must comply with Federal
Communications Commission
(FCC) guidelines that limit radio
frequency energy (RF)
exposures. The FCC established
these guidelines in consultation
with the FDA and the other
federal health and safety
agencies. The FCC limit for RFexposure from wireless
telephones is set at a Specific
Absorption Rate (SAR) of 1.6watts per kilogram (1.6 W/kg).
The FCC limit is consistent with
the safety standards developed
by the Institute of Electrical and
Electronic Engineering (IEEE) and
the National Council on
Radiation Protection and
Measurement. The exposure limit
takes into consideration the
body’s ability to remove heat
from the tissues that absorb
energy from the wireless phone
and is set well below levels
known to have effects.
Manufacturers of wireless phones
must report the RF exposure
level for each model of phone to
the FCC. The FCC website
(http://www.fcc.gov/oet/rfsafety
) gives directions for locating the
FCC identification number on
your phone so you can find your
phone’s RF exposure level in the
online listing. 
8. What has the FDA done to
measure the radio frequency 
						

							Safety Guidelines
80
Safety Guidelines
energy coming from wireless
phones? 
The Institute of Electrical and
Electronic Engineers (IEEE) is
developing a technical standard
for measuring the radio
frequency energy (RF) exposure
from wireless phones and other
wireless handsets with the
participation and leadership of
FDA scientists and engineers.
The standard, ‘Recommended
Practice for Determining the
Spatial Peak Specific Absorption
Rate (SAR) in the Human Body
Due to Wireless Communications
Devices: Experimental
Techniques,’ sets forth the first
consistent test methodology for
measuring the rate at which RF is
deposited in the heads of
wireless phone users. The test
method uses a tissuesimulating
model of the human head.
Standardized SAR test
methodology is expected togreatly improve the consistency
of measurements made at
different laboratories on the
same phone. SAR is the
measurement of the amount of
energy absorbed in tissue, either
by the whole body or a small
part of the body. It is measured
in watts/kg (or milliwatts/g) of
matter. This measurement is usedto determine whether a wireless
phone complies with safety
guidelines. 
9. What steps can I take to
reduce my exposure to
radiofrequency energy from
my wireless phone? 
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 you
are concerned about avoiding
even potential risks, you can take
a few simple steps to minimizeyour exposure to radiofrequency
energy (RF). Since time is a key
