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

Radio frequency energy (RF) from wireless phones can interact with 
some electronic devices. For this reason, FDA helped develop a
