What steps can I take to reduce my exposure to radio
frequency energy from my wireless phone?
If there is a risk from these products - and at this point we do not know that there is 
- it is probably very small. But if you are concerned about avoiding even potential 
risks, you can take a few simple steps to minimize your exposure to radio frequency 
energy (RF). Since time is a key factor in how much exposure a person receives, 
reducing the amount of time spent using a wireless phone will reduce RF exposure.
•
If you must conduct extended conversations by wireless phone every day, you
could place more distance between your body and the source of the RF, since the 
exposure level drops off dramatically with distance. For example, you could use a 
headset and carry the wireless phone away from your body or use a wireless 
phone connected to a remote antenna.
Again, the scientific data do not demonstrate that wireless phones are harmful. But if 
you are concerned about the RF exposure from these products, you can use 
measures like those described above to reduce your RF exposure from wireless 
phone use.
What about children using wireless phones?
The scientific evidence does not show a danger to users of wireless phones, 
including children and teenagers. If you want to take steps to lower exposure to 
radio frequency energy (RF), the measures described above would apply to children 
and teenagers using wireless phones. Reducing the time of wireless phone use and 
increasing the distance 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
