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.   
Do hands-free kits for wireless phones reduce risks from exposure 
to RF emissions? 
Since there are no known risks from exposure to RF emissions from 
wireless phones, there is no reason to believe that hands-free kits reduce 
risks. Hands-free kits can be used with wireless phones for convenience 
and comfort. These systems reduce the absorption of RF energy in the 
head because the phone, which is the source of the RF emissions, will not 
be placed against the head. On the other hand, if the phone is mounted 
against the waist or other part of the body during use, then that part of 
the body will absorb more RF energy. Wireless phones marketed in the 
U.S. are required to meet safety requirements regardless of whether they 
are used against the head or against the body. Either configuration should 
result in compliance with the safety limit. 
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
