Again, the scientific data do not demonstrate that wireless phones

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 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 radiofrequency energy (RF), the measures 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?

Radiofrequency 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 in 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.

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 phones.

The FDA's microwave oven standard is an emission standard (as

opposed to an exposure standard) that allows specific levels of

microwave leakage (measured at five centimeters from the oven

surface). The standard also requires ovens to have two independent

interlock systems that prevent the oven from generating microwaves

the moment that the latch is released or the door of the oven is

opened. The FDA has stated that ovens that meet its standards and are

used according to the manufacturer's recommendations are safe for

consumer and industrial use. More information is available from:

www.fda.gov/cdrh.

The EPA has, in the past, considered developing federal guidelines for

public exposure to RF radiation. However, EPA activities related to RF

safety and health are presently limited to advisory functions. For

example, the EPA now chairs an Inter-agency Radiofrequency
