radiofrequency energy (RF). Since time is a key factor in how much

exposure a person receives, reducing the amount of time spent using

a wireless smartphone will reduce RF exposure.

If you must conduct extended conversations by wireless smartphone

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 smartphone away from your body or use a wireless

smartphone connected to a remote antenna.

Again, the scientific data do not demonstrate that wireless

smartphones are harmful. But if you are concerned about the RF

exposure from these products, you can use measures like those

described above to reduce your RF exposure from wireless

smartphone use.

What about children using wireless smartphones? The scientific

evidence does not show a danger to users of wireless smartphones,

including children and teenagers. If you want to take steps to lower

exposure to radiofrequency energy (RF), the measures described

above would apply to children and teenagers using wireless

smartphones. Reducing the time of wireless smartphone 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 smartphones 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 smartphone

causes brain tumors or other ill effects. Their recommendation to limit

wireless smartphone use by children was strictly precautionary; it

was not based on scientific evidence that any health hazard exists.

What about wireless smartphone interference with medical

equipment? Radiofrequency energy (RF) from wireless

smartphones 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 in late 2000. This standard will allow manufacturers to

ensure that cardiac pacemakers and defibrillators are safe from

wireless smartphone EMI.

FDA has tested hearing aids for interference from handheld wireless

smartphones 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 smartphones so that no interference occurs

when a person uses a “compatible” smartphone 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 smartphones 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.

Which other federal agencies have responsibilities related to

potential RF health effects? Certain agencies in the Federal

Government have been involved in monitoring, researching or

regulating issues related to human exposure to RF radiation. These

agencies include the Food and Drug Administration (FDA), the

Environmental Protection Agency (EPA), the Occupational Safety and

Health Administration (OSHA), the National Institute for Occupational

Safety and Health (NIOSH), the National Telecommunications and

Information Administration (NTIA) and the Department of Defense

(DOD).

By authority of the Radiation Control for Health and Safety Act of

1968, the Center for Devices and Radiological Health (CDRH) of the

FDA develops performance standards for the emission of radiation

from electronic products including X-ray equipment, other medical

devices, television sets, microwave ovens, laser products and

sunlamps. The CDRH established a product performance standard for

microwave ovens in 1971 limiting the amount of RF leakage from

ovens. However, the CDRH has not adopted performance standards

for other RF-emitting products. The FDA is, however, the lead federal

health agency in monitoring the latest research developments and

advising other agencies with respect to the safety of RF-emitting

products used by the public, such as cellular and PCS smartphones.
