8. 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.
9. 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 hearing aids for interference from 
handheld 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.
10.What are the results of the research done
already?
The research done thus far has produced conflicting 
results, and many studies have suffered from flaws 
in their research methods. Animal experiments 
investigating the effects of radio frequency energy 
(RF) exposures characteristic of wireless phones 
have yielded conflicting results that often cannot be 
repeated in other laboratories. A few animal studies, 
however, have suggested that low levels of RF could 
accelerate the development of cancer in laboratory 
animals. However, many of the studies that showed 
increased tumor development used animals that had 
been genetically engineered or treated with cancer-
causing chemicals so as to be pre-disposed to 
develop cancer in the absence of RF exposure. Other 
studies exposed the animals to RF for up to 22 hours 
per day. These conditions are not similar to the 
conditions under which people use wireless phones, 
so we don t know with certainty what the results of 
such studies mean for human health.
