Although the existing scientific data do not justify FDA 
regulatory actions, FDA has urged the wireless phone 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 RF 
exposure to the user that it 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.
FDA belongs to a 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 agencies belong to this working group:
 ●National Institute for Occupational Safety and Health ●Environmental Protection Agency
 ●Federal Communications Committee
 ●Occupational Safety and Health Administration
The National Institutes of Health participates in some 
interagency working group activities, as well.
FDA shares regulatory responsibilities about wireless phones 
with the Federal Communications Commission (FCC). All phones 
that are sold in the United States must comply with FCC safety 
guidelines that limit RF exposure. FCC relies on FDA and other 
health agencies for safety questions about wireless phones.
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 wireless 
exposures that people get from these base stations are typically 
thousands of times lower than those they get from wireless 
phones. Base stations are thus not the subject of the safety 
questions discussed in this document.

What kinds of phones are the subject of this 
update?
The term “wireless phones” refers here to hand-held wireless 
phones with built-in antennas, often called “cell,” “mobile,” or 
“PCS”. These types of wireless phones can expose the user to 
measurable radio frequency energy (RF) because of the short 
distance between the phone and the user’s head. These RF 
exposures are limited by Federal Communications Commission 
safety guidelines that were developed with the advice of 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 so-called 
“cordless phones” which have a base unit connected to the 
phone wiring in a house, typically operate at far lower per 
levels, and thus produce RF exposures far below the FCC safety 
limits.
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 radio 
frequency 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 absence of RF exposure. Other studies exposed the 
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 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, glaucoma, 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 phones RF 
exposures. However, none of the studies can answer questions 
about long-term exposures, since average period of phone use 
in these studies was around three years.
What research is needed to decide whether RF 
exposure from wireless phones poses a health 
threat?
A combination 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 large 
numbers 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 ten or more years’ follow-up may be needed to 
provide answers about some health effects, such as cancer. This 
is because the interval between the time of exposure to a 
cancer-causing 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 day-to-day 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.

What is FDA doing to find out more about the 
possible health effects of wireless phone RF?
FDA is working with the U.S. 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 radio frequency 
energy (RF).
FDA has been a leading participant in the World Health 
Organization International Electromagnetic Fields (EMF) Project 
since its inception in 1996. An influential result of tis 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.
FDA and the Cellular Telecommunications & Internet Association 
(CTIA) have a formal Cooperative Research and Development 
Agreement (CRADA) to do research on wireless phone safety. 
FDA provides the scientific oversight, obtaining input from 
experts in government, industry, and academic organizations. 
CTIA-funded research is conducted through contracts to 
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.

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. FCC established these 
guidelines in consultation with FDA and other federal health and 
safety agencies. The FCC limit for exposure from wireless 
telephones is set at a Specific Absorption Rate (SAR) of 1.6 
watts 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 tissue 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.
What has FDA done to measure the radio 
frequency 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 hand sets 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 tissue-simulating model of the human head.

Standardized SAR test methodology is expected to greatly 
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 used to determine 
whether a wireless phone complies with safety guidelines.
What steps can I take to reduce my exposure to 
radio frequency 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 minimize your exposure to radio frequency 
energy (RF). Since time is a key factor in how much exposure a 
person receives, reducing the amount of time spent using a 
wireless phone will reduce RF exposure.
If you must conduct extended conversations by wireless phone 
every day, you could place more distance between your body 
and the source of the RF, since the exposure level drops off 
dramatically with distance. For example, you could use a 
headset and carry the wireless phone away from your body or 
use a wireless phone connected to a 
remote antenna.
Again, the scientific data do not
 demonstrate that wireless 
phones are harmful. But if you are concerned about RF 
exposure from these products, you can use measures like those 
described above to reduce your RF exposure from wireless 
phone use.

What about children using wireless phones?
The scientific evidence does not show a danger to users of 
wireless phones, including children and teenagers. If you want 
to take steps to lower exposure to radio frequency energy (RF), 
the measured described above would apply to children and 
teenagers using wireless phones. Reducing the time of wireless 
phone use and increasing the distance between the user and 
the RF source will reduce RF exposure.
Some groups sponsored by other national governments have 
advised that children be discouraged from using wireless 
phones at all. For example, the government in the United 
Kingdom distributed leaflets containing such a recommendation 
in December 2000. They noted that no evidence exists that 
using a wireless phone causes brain tumors or other ill effects. 
Their recommendation to limit wireless phone use by children 
was strictly precautionary; it was not based on scientific 
evidence that any health hazard exists.
What about wireless phone interference with
medical equipment?
Radio frequency energy (RF) from wireless phones can interact 
with some electronic devices. For this reason, FDA helped 
develop a detailed test method to measure electromagnetic 
interference (EMI) of implanted cardiac pacemakers and 
defibrillators from wireless telephones. This test method is now 
part of a standard sponsored by the Association for the 
Advancement of Medical instrumentation (AAMI). The final 
draft, a joint effort by FDA, medical device manufacturers, and 
many other groups, was completed on late 2000. This standard 
will allow manufacturers to ensure that cardiac pacemakers and 
defibrillators are safe from wireless phone EMI.

FDA has tested hearing aids for interference from handheld 
wireless phones and helped develop a voluntary standard 
sponsored by the Institute of Electrical and Electronic Engineers 
(IEEE). This standard specifies test methods and performance 
requirements for hearing aids and wireless phones so that no 
interference occurs when a person uses a “compatible” phone 
and a “compatible” hearing aid at the same time. This standard 
was approved by the IEEE in 2000.
FDA continues to monitor the use of wireless phones for 
possible interactions with other medical devices. Should 
harmful interference be found to occur, FDA will conduct testing 
to assess the interference and work to resolve 
the problem.

CTIA Safety Information
Exposure to radio frequency signals
Your wireless hand held portable telephone is a low power radio 
transmitter and receiver. When it is ON, it receives and also 
sends out radio frequency (RF) signals.
In August, 1996, the Federal Communications Commissions 
(FCC) adopted RF exposure guidelines with safety levels for 
hand-held wireless phones. Those guidelines are consistent 
with the safety standards previously set by both U.S. and 
international standard bodies:
 ●ANSI C95.1 (1992)
 ●NCRP Report 86 (1986)
 ●ICNIRP (1996)
Those standards were based on comprehensive and periodic 
evaluations of the relevant scientific literature. For example, 
over 120 scientists, engineers, and physicians from universities, 
government health agencies, and industry reviewed the 
available body of research to develop the ANSI Standard 
(C95.1).
The design of your phone complies with the FCC guidelines (and 
those standards).
Antenna care
Use only the specified of approved replacement antenna. 
Unauthorized antennas, modifications, or attachments could 
damage the phone and may violate FCC regulations.

Phone operation
NORMAL POSITION: Hold the phone as you would any other 
telephone with the antenna pointed up and over your shoulder.
Tips on efficient operation:
For your phone to operate most efficiently:
 ●Extend your antenna fully.
 ●Do not touch the antenna unnecessarily when the phone is 
in use. Contact with the antenna affects call quality and 
may cause the phone to operate at a higher power level 
than otherwise needed.
Driving
Check the laws and regulations on the use of wireless 
telephones in the areas where you drive. Always obey them. 
Also, if using your phone while driving, please:
 ●Give full attention to driving--driving safety is your 
first responsibility.
 ●Use hands-free operation, if available.
 ●Pull off the road and park before making or answering a 
call if driving conditions so require.
