Consumer Information on Wireless Phones
Do wireless phone accessories that claim to shield the
head from RF radiation work?
Since there are no known risks from exposure to RF emissions from wireless
phones, there is no reason to believe that accessories that claim to shield the
head from those emissions reduce risks. Some products that claim to shield
the user from RF absorption use special phone cases, while others involve
nothing more than a metallic accessory attached to the phone. Studies have
shown that these products generally do not work as advertised. Unlike
"hands-free" kits, these so-called "shields" may interfere with proper
operation of the phone. The phone may be forced to boost its power to
compensate, leading to an increase in RF absorption. In February 2002, the
Federal trade Commission (FTC) charged two companies that sold devices
that claimed to protect wireless phone users from radiation with making
false and unsubstantiated claims. According to FTC, these defendants
lacked a reasonable basis to substantiate their claim.
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 in
late 2000. This standard will allow manufacturers to ensure that cardiac
pacemakers and defibrillators are safe from wireless phone EMI. FDA has
tested wireless phones and helped develop a voluntary standard sponsored
by the Institute of Electrical and Electronic Engineers (IEEE). This standard
