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 radiofrequency
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.
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
handsfree 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.
