they are used against the head or against the body. Either configuration should result in

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.
