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 "hand-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 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.
